Configuration files are all installed into VoIPong directory: /usr/local/etc/voipong. Main configuration parameters are included in voipong.conf file. voipongnets file maps network addresses to their proper algorithms. DSOM modules for g711-ulaw and g711-alaw (modvocoder_pcmu.so, modvocoder_pcma.so) are installed to the path given with the modpath configuration file directive.
Configuration file: voipong.conf
Runtime configuration parameters vital to the smoothly operation of VoIPong server are defined in voipong.conf, formatted as a standart .ini file. There are two sections: GENERAL for general server settings, and FILTERS for setting up startup filters.
GENERAL sectionlogdir: specifies the log directory where voipong will save its logs e.g. /var/loglogfile: name of the main server log file e.g. voipong.logoutdir: path where output .WAV and/or .RAW files are to be written. e.g. /var/log/voipoutputcdrfile: name of the CDR (Common Data Record) log file e.g. cdr.lognetworksfile: path to the network/algorithm mappings file e.g. /usr/local/etc/voipong/voipongnetspidfile: path to the pidfile e.g. /var/run/voipong.pidsoxpath: path to the sox executable e.g. /usr/local/bin/soxmodpath: path to the directory where vocoder DSOM modules are installed. e.g. /usr/local/etc/voipong/modulessoxmixpath: path to the soxmix executable e.g. /usr/local/bin/soxmixmgmt_ipcpath: path to the UNIX domain socket for management console e.g. /tmp/voipongmgmt.sockdefalg: Default packet matching algorithm. This can currently only be lfp. Other algorithms are to be developed. e.g. lfprtp_idle_time: (in seconds) when this amount of time elapses and no RTP traffic is received for the call, the call is considered to be finished. e.g. 10device: network device to sniff packets from e.g. eth0promisc: set this to true 1 if you want VoIpong to set your sniffing device to promiscious mode. e.g. set this to 1 for true, 0 for false.mixwaves: set this to true 1 if you want VoIPong to mix the seperate .WAV files into a single .WAV file. e.g. set this to 1 for true, 0 for false.snaplen: maximum number of bytes to capture e.g. 1500readtmt: specifies the read-from-device timeout in milliseconds. e.g. 500FILTERS sectionstartup: Pcap filter string. This filter will be set during startup procedures. To see detailed usage of pcap filters, see pcap(3) manual page. e.g. "udp"Network - Algorithm mappings: voipongnets
Sniffing out voice is a tough task. You cannot design an algorithm and expect to catch all the VoIP calls. VoIP is relatively new and it is not a highly standardized technology. So there have to be several call catching algorithms for various setups. VoIPong provides a framework where you can set the call catching algorithm which you think will best suit your VoIP infrastructure. This results in a much more specialized and successful call sniffing.
Least False Positive (LFP) algorithm
This algorithm tries to detect calls generated via VoIP devices conforming to RTP and RTCP RFCs. This algorithm should detect and record a broad range of calls. The most obvious advantage of this algorithm is that you'll have barely no false positives. This is why this method is named as LFP. The #1 disadvantage will be that this will not be able to catch calls if there are no RTCP packets or the devices do not conform to RFCs. To use this algorithm, you will need to specify a network to use with it in your voipongnets file.
172.16.1.0/255.255.255.0 lfp10.30.0.0/255.255.252.0 lfpFixed (Fixed Port) algorithm
Some VoIP devices (e.g. Grandstream(TM) IP adapters) use a fixed port to send and receive RTP datagrams, and they do not conform to RFCs, and do not send any link control information (RTCP packets). If you have such devices in your network, you can specify their algorithm as fixed in the voipongnets file. This algorithm cannot be used with networks, it can only be used with hosts, so netmask address should always be 255.255.255.255. Please note that, after the fixed keyword, you are expected to set the fixed port number the device is using. For example, suppose that you have a device which uses port 40000 to send RTP packets, you should add this line to your voipongnets file:
172.16.1.101/255.255.255.255 fixed 40000LRA-SIP Algorithm
LRA-SIP will follow SIP signalling packets, and will spot the RTP/RTCP session from the SDP packets. This algorithm is not implemented yet, however I will be working on it for the next release (probably 2.1.?)

Since release 2.0 upwards, VoIPong provides a powerful dynamic framework for loading of 3rd party voice decoders into the running voipong executable at runtime. This is called Dynamic Shared Object Modules (DSOM) Framework. Simply put, DSOM vocoder modules are shared libraries with the .so extension. VoIPong looks for those shared libraries in the preconfigured modpath directory, loads them one by one. DSOM engine resident at VoIPong core, spots the initialization method in the shared module and invokes it allowing the module to register itself inside VoIPong runtime environment:
07/12/05 13:29:25: loadmodule: /usr/local/etc/voipong/modules/modvocoder_pcmu.so (@0x2813e370)
07/12/05 13:29:25: loadmodule: /usr/local/etc/voipong/modules/modvocoder_pcma.so (@0x28140390)
07/12/05 13:29:25: loaded 2 module(s)
For security reasons, the DSOMs are expected to be owned by the same user and group who is running the core VoIPong executable. For instance, if the user running the program has uid 1000 and gid 10; the modules should also be owned by uid 1000 and gid 10.
The naming convention is that the modules should start with the modvocoder_ keyword, and should include the name of the decoder in the module, followed by the .so extension. For example, the correct name for the g711 (u-law) module can be modvocoder_pcmu.so.
There are two pre-written voice decoder modules with VoIPong release 2.0:
modvocoder_pcmu.so: g711 (u-law) decoder (payload type 0)modvocoder_pcma.so: g711 (a-law) decoder (payload type 8)
To code and install your own vocoder module (i.e. for g726), VoIPong DSOM Decoder Writer's Guide will be available soon.

You can try VoIPong with Microsoft Netmeeting. Set up netmeeting so that it uses G711 at both ends, and make a voice call. You'll see the calls captured and wave files created after your call finishes.
If you do not have a testbed, do not want so much pain to test VoIPong, you can replay a test capture file in your machine and see if it is catched.
Replaying a previous capture fileDownload this test call capture, where me and Baris are talking about EnderUNIX team.Download and install tcpreplay tool. Tcpreplay tool reads pcap capture files, and re-injects the packets into a live network.Start VoIPong

You should have pcap library installed beforehand. Please download libpcap from tcpdump.org and install it if you don't have it in your system. Please note that most Operating Systems and Linux distributions provide this library in their default installations.
Also, for .WAV file creation, you should have sox and soxmix tools installed. If you don't have those, please download them from sox.sourceforge.net and install it in your system.
Compilation & Installation
Download the latest VoIPong tarball from EnderUNIX and uncompress it:
&prompt.root; tar zxvf voipong-version.tar.gz
There are several pre-written Makefile files in the source directory. Examine each of
them and choose the one which most suits your system. If you're running of the
the BSD type Operating Systems (i.e. FreeBSD, OpenBSD, NetBSD, Mac OSX) copy
Makefile.bsd as Makefile; if you're using a Linux distribution then, copy
Makefile.linux as Makefile. You might need to change CFLAGS and LDFLAGS variables accordingly:
&prompt.root; cp Makefile.bsd Makefile
Type make to compile voipong, voipctl and voice decoder modules:
&prompt.root; make
Type make install to copy compiled binaries, shared modules, configuration files, manual pages and related documentation into the proper locations:
&prompt.root; make install Installation via BSD ports system
BSD Operating Systems (FreeBSD, NetBSD, OpenBSD, Darwin etc.) has a ports system for easy package administration. VoIPong is a FreeBSD port, so you can install it from FreeBSD ports tree. VoIPong is located in /usr/ports/audio/voipong directory:
Change your current working directory to /usr/ports/audio/voipong and type:
&prompt.root; cd /usr/ports/audio/voipong
&prompt.root; make install clean
FreeBSD will fetch the tarball, uncompress it, compile the sources and install VoIPong for you.
Alternatively, you can install VoIPong .tbz package with pkg_add (1) command:
&prompt.root; fetch \

VoIPong is a sniffer utility which tries to detects Voice Over IP calls on a pipeline, and for those which have vocoder modules loaded, dumps actual conversation to seperate wave files. Currently it can catch calls made via a wide variety of protocols including SIP, H323, Cisco's Skinny Client Protocol. It can also catch calls made through dummy IP adapters which do not do any signalling but transport voice payload via RTP protocol.
It's been written in C language for performance reasons, proved to be running on Solaris, Linux and FreeBSD; though it's thought to compile and run on other platforms as well.
On a 45 Mbit/sec actual network traffic, it's been verified that VoIPong successfully detected all VoIP gateways and the VoIP calls. CPU utilization during the run has been found ranging between 66% - 80% on a 256MB RAM, Celeron 1700 Mhz Toshiba notebook.
With its powerful and extensible Dynamic Shared Object Modules (DSOM) subsystem, and its related API (will be documented later), new third party voice decoder modules can be coded and installed, resulting in a great flexibility. By default, VoIPong comes with two pre-written voice decoder modules for calls encoded with G711 (u-law) and G711 (a-law) . Audible output can be generated for calls encoded with any one of them.

Similar to other sniffer tools at the market, VoIPong needs to get a copy of the voice traffic you're interested in. If you're sharing a hub with one of the endpoints of the voice conversation, you will not need to do anything, since hub devices inherently copy traffic to all its ports. If you are in a switched environment, some network administration will be needed. Most modern switch devices has a handy "monitor port" which you can use for copying traffic going through one or more switch ports. So you'll need to copy one of the endpoints' traffic to that monitor port, and connect the computer on which VoIPong is running. If you're running VoIPong on a gateway machine, where this machine has already access to all the voice traffic, you will not need to do anything.
Startup Parameters
You can use -h switch to see available startup parameters:
[murat@efe ~/voipong]$ ./voipong -h
usage: voipong [options]
options:
-h this screen
-v version info
-f run in foreground (don't become a daemon)
-d debug level. Valid levels are 0 through 4. Default: 0
-c config file path
-v switch shows VoIPong version information:
[murat@efe ~/voipong]$ ./voipong -v

You can set the debug log level by -d switch. Valid levels are 0 through 4, latter being the most verbose. Default configuration file is /usr/local/etc/voipong/voipong.conf. You can use alternate configuration file by issuing -c switch and providing full path to the alternate configuration file. If you don't want VoIPong to daemonize, but instead you want it to stay at your terminal and dump log messages to the terminal, you will need to issue -f switch.
So, If you want VoIPong to stay at the terminal, and you want to see as many log messages as possible, you should fire VoIPong as such:

Running VoIPong with a non-privileged user
It is strongly advised that you avoid running VoIPong with super-user, but use a non-privileged special user created only for it. This section describes the steps you should take to accomplish this. Note that these steps should be done after you compiled and installed VoIPong successfully.
Create voipong user and group
&prompt.root; pw group add voipong
&prompt.root; pw user add voipong -g voipong -m -s /usr/local/bin/bashChange ownership of voipong, voipctl and /usr/local/etc/voipong directory to voipong user:
&prompt.root; chown voipong /usr/local/bin/voipong
&prompt.root; chown voipong /usr/local/bin/voipctl
&prompt.root; chown -R voipong /usr/local/etc/voipong
&prompt.root; chgrp -R voipong /usr/local/etc/voipongChange ownership of BPF device files (/dev/bpf*) to voipong user:
&prompt.root; chown voipong /dev/bpf*Switch user to voipong:
&prompt.root; su - voipong
To see all of the directories on your FreeBSD system, type
ls -R / | more
-- Dru genesis@istar.ca
&prompt.user;
Create runtime directories:
&prompt.user; mkdir logs
&prompt.user; mkdir output
&prompt.user; mkdir runChange log, pid and output directory paths to the new directories in voipong.conf
logdir = /home/voipong/logs/
logfile = voipong.log
outdir = /home/voipong/output/
cdrfile = /home/voipong/output/voipcdr.log
pidfile = /home/voipong/run/voipong.pid
mgmt_ipcpath = /home/voipong/run/voipongmgmt.sockYou can now run voipong
&prompt.user; id
uid=1042(voipong) gid=1042(voipong) groups=1042(voipong)

VoIPong User's Manual
VoIPong is a sniffer utility which tries to detects Voice Over IP calls on a pipeline,
and for those which have vocoder modules loaded, dumps actual conversation to seperate
wave files. Currently it can catch calls made via a wide variety of protocols including
SIP, H323, Cisco's Skinny Client
Protocol. It can also catch calls made through dummy IP adapters which do not
do any signalling but transport voice payload via RTP protocol.
It's been written in C language for performance reasons, proved to be running on Solaris, Linux and FreeBSD; though it's
thought to compile and run on other platforms as well.
On a 45 Mbit/sec actual network traffic, it's been verified that VoIPong successfully
detected all VoIP gateways and the VoIP calls. CPU utilization during the run has been
found ranging between 66% - 80% on a 256MB RAM, Celeron 1700 Mhz Toshiba notebook.
With its powerful and extensible Dynamic
Shared Object Modules (DSOM) subsystem, and its related API (will be
documented later), new third party voice decoder modules can be coded and installed,
resulting in a great flexibility. By default, VoIPong comes with two pre-written voice
decoder modules for calls encoded with G711
(u-law) and G711 (a-law)
. Audible output can be generated for calls encoded with any one of them.
You should have pcap library installed beforehand. Please
download libpcap from tcpdump.org and install it if you don't have it in your system. Please
note that most Operating Systems and Linux distributions provide this library in their
default installations.
Also, for .WAV file creation, you should have sox and soxmix tools installed. If you don't have those, please download
them from sox.sourceforge.net and
install it in your system.
Download the latest VoIPong tarball from EnderUNIX and uncompress it:
#tar zxvf voipong-version.tar.gz
There are several pre-written Makefile files in the source
directory. Examine each of them and choose the one which most suits your system. If
you're running of the the BSD type Operating Systems (i.e. FreeBSD, OpenBSD, NetBSD, Mac
OSX) copy Makefile.bsd as Makefile;
if you're using a Linux distribution then, copy Makefile.linux
as Makefile. You might need to change CFLAGS and LDFLAGS variables
accordingly:
#cp Makefile.bsd Makefile
Type make to compile voipong, voipctl and voice decoder modules:
#make
Type make install to copy compiled binaries, shared modules,
configuration files, manual pages and related documentation into the proper locations:
BSD Operating Systems (FreeBSD, NetBSD, OpenBSD, Darwin etc.) has a ports system for
easy package administration. VoIPong is a FreeBSD port, so you can install it from
FreeBSD ports tree. VoIPong is located in /usr/ports/audio/voipong directory:
Change your current working directory to /usr/ports/audio/voipong and type:
#cd /usr/ports/audio/voipong#make install clean
FreeBSD will fetch the tarball, uncompress it, compile the sources and install VoIPong
for you.
Alternatively, you can install VoIPong .tbz package with pkg_add (1) command:
Since release 2.0 upwards, VoIPong provides a powerful dynamic framework for loading
of 3rd party voice decoders into the running voipong executable at runtime. This is
called Dynamic Shared Object Modules (DSOM) Framework. Simply put, DSOM vocoder modules
are shared libraries with the .so extension. VoIPong looks for
those shared libraries in the preconfigured modpath directory,
loads them one by one. DSOM engine resident at VoIPong core, spots the initialization
method in the shared module and invokes it allowing the module to register itself inside
VoIPong runtime environment:
For security reasons, the DSOMs are expected to be owned by the same user and group
who is running the core VoIPong executable. For instance, if the user running the program
has uid 1000 and gid 10; the modules should also be owned by uid 1000 and gid 10.
The naming convention is that the modules should start with the modvocoder_ keyword, and should include the name of the decoder in
the module, followed by the .so extension. For example, the
correct name for the g711 (u-law) module can be modvocoder_pcmu.so.
There are two pre-written voice decoder modules with VoIPong release 2.0:
modvocoder_pcmu.so: g711 (u-law) decoder (payload type
0)
modvocoder_pcma.so: g711 (a-law) decoder (payload type
8)
To code and install your own vocoder module (i.e. for g726), VoIPong DSOM Decoder
Writer's Guide will be available soon.
Configuration files are all installed into VoIPong directory: /usr/local/etc/voipong. Main configuration parameters are included
in voipong.conf file. voipongnets
file maps network addresses to their proper algorithms. DSOM modules for g711-ulaw and g711-alaw (modvocoder_pcmu.so, modvocoder_pcma.so) are installed to the path given with the modpath configuration file directive.
Runtime configuration parameters vital to the smoothly operation of VoIPong server are
defined in voipong.conf, formatted as a standart .ini file. There are two sections: GENERAL for general server settings, and
FILTERS for setting up startup
filters.
logdir: specifies the log directory where voipong will save
its logs e.g. /var/log
logfile: name of the main server log file e.g. voipong.log
outdir: path where output .WAV and/or .RAW files are to be
written. e.g. /var/log/voipoutput
cdrfile: name of the CDR (Common Data Record) log file e.g.
cdr.log
networksfile: path to the network/algorithm mappings file
e.g. /usr/local/etc/voipong/voipongnets
pidfile: path to the pidfile e.g. /var/run/voipong.pid
soxpath: path to the sox executable e.g. /usr/local/bin/sox
modpath: path to the directory where vocoder DSOM modules are
installed. e.g. /usr/local/etc/voipong/modules
soxmixpath: path to the soxmix executable e.g. /usr/local/bin/soxmix
mgmt_ipcpath: path to the UNIX domain socket for management
console e.g. /tmp/voipongmgmt.sock
defalg: Default packet matching algorithm. This can currently
only be lfp. Other algorithms are to be developed. e.g. lfp
rtp_idle_time: (in seconds) when this amount of time elapses
and no RTP traffic is received for the call, the call is considered to be finished. e.g.
10
device: network device to sniff packets from e.g. eth0
promisc: set this to true 1 if you
want VoIpong to set your sniffing device to promiscious mode. e.g. set this to 1 for true, 0 for false.
mixwaves: set this to true 1 if you
want VoIPong to mix the seperate .WAV files into a single .WAV file. e.g. set this to 1 for true, 0 for false.
snaplen: maximum number of bytes to capture e.g. 1500
readtmt: specifies the read-from-device timeout in
milliseconds. e.g. 500
startup: Pcap filter string. This filter will be set during
startup procedures. To see detailed usage of pcap filters, see pcap(3) manual page. e.g.
"udp"
Sniffing out voice is a tough task. You cannot design an algorithm and expect to catch
all the VoIP calls. VoIP is relatively new and it is not a highly standardized
technology. So there have to be several call catching algorithms for various setups.
VoIPong provides a framework where you can set the call catching algorithm which you
think will best suit your VoIP infrastructure. This results in a much more specialized
and successful call sniffing.
This algorithm tries to detect calls generated via VoIP devices conforming to RTP and RTCP RFCs. This algorithm should detect and record a broad
range of calls. The most obvious advantage of this algorithm is that you'll have barely
no false positives. This is why this method is named as LFP. The #1 disadvantage will be
that this will not be able to catch calls if there are no RTCP packets or the devices do not conform to RFCs. To use
this algorithm, you will need to specify a network to use with it in your voipongnets
file.
Some VoIP devices (e.g. Grandstream(TM) IP adapters) use a fixed port to send and
receive RTP datagrams, and they do not conform to RFCs, and do not send any link control
information (RTCP packets). If you have such devices in your network, you can specify
their algorithm as fixed in the voipongnets file. This
algorithm cannot be used with networks, it can only be used with hosts, so netmask
address should always be 255.255.255.255. Please note that, after
the fixed keyword, you are expected to set the fixed port number the device is using. For
example, suppose that you have a device which uses port 40000 to
send RTP packets, you should add
this line to your voipongnets file:
LRA-SIP will follow SIP
signalling packets, and will spot the RTP/RTCP session from the SDP packets. This algorithm is not implemented yet, however I
will be working on it for the next release (probably 2.1.?)
Similar to other sniffer tools at the market, VoIPong needs to get a copy of the voice
traffic you're interested in. If you're sharing a hub with one of the endpoints of the voice conversation, you
will not need to do anything, since hub devices inherently copy traffic to all its ports.
If you are in a switched
environment, some network administration will be needed. Most modern switch devices has a
handy "monitor port" which you can
use for copying traffic going through one or more switch ports. So you'll need to copy
one of the endpoints' traffic to that monitor port, and connect the computer on which
VoIPong is running. If you're running VoIPong on a gateway machine, where this machine has already access to all
the voice traffic, you will not need to do anything.
You can use -h switch to see available startup
parameters:
[murat@efe ~/voipong]$ ./voipong -h
usage: voipong [options]
options:
-h this screen
-v version info
-f run in foreground (don't become a daemon)
-d debug level. Valid levels are 0 through 4. Default: 0
-c config file path
-v switch shows VoIPong version information:
[murat@efe ~/voipong]$ ./voipong -v

You can set the debug log level by -d switch. Valid levels are
0 through 4, latter being the most
verbose. Default configuration file is /usr/local/etc/voipong/voipong.conf. You can use alternate
configuration file by issuing -c switch and providing full path
to the alternate configuration file. If you don't want VoIPong to daemonize, but instead
you want it to stay at your terminal and dump log messages to the terminal, you will need
to issue -f switch.
So, If you want VoIPong to stay at the terminal, and you want to see as many log
messages as possible, you should fire VoIPong as such:

Omer Faruk Sen has maintains VoIPong LiveCD! based on FreeSBIE project. LiveCD is an
ISO image which can be burnt into a blank CD directly, and includes pre-installed VoIPong
release along with several boot-time scripts for configuring the OS and VoIPong.
You can try VoIPong with Microsoft Netmeeting. Set up netmeeting so that it uses G711
at both ends, and make a voice call. You'll see the calls captured and wave files created
after your call finishes.
If you do not have a testbed, do not want so much pain to test VoIPong, you can replay
a test capture file in your machine and see if it is catched.
Download and install tcpreplay tool. Tcpreplay tool reads pcap capture files, and
re-injects the packets into a live network.

VoIPong User's Manual
VoIPong is a sniffer utility which tries to detects Voice Over IP calls on a pipeline,
and for those which have vocoder modules loaded, dumps actual conversation to seperate
wave files. Currently it can catch calls made via a wide variety of protocols including
SIP, H323, Cisco's Skinny Client
Protocol. It can also catch calls made through dummy IP adapters which do not
do any signalling but transport voice payload via RTP protocol.
It's been written in C language for performance reasons, proved to be running on Solaris, Linux and FreeBSD; though it's
thought to compile and run on other platforms as well.
On a 45 Mbit/sec actual network traffic, it's been verified that VoIPong successfully
detected all VoIP gateways and the VoIP calls. CPU utilization during the run has been
found ranging between 66% - 80% on a 256MB RAM, Celeron 1700 Mhz Toshiba notebook.
With its powerful and extensible Dynamic
Shared Object Modules (DSOM) subsystem, and its related API (will be
documented later), new third party voice decoder modules can be coded and installed,
resulting in a great flexibility. By default, VoIPong comes with two pre-written voice
decoder modules for calls encoded with G711
(u-law) and G711 (a-law)
. Audible output can be generated for calls encoded with any one of them.
Chapter 2. Features
Simple, optimized, extendable, fast code
Easy debugging
Easy installation and administration
Powerful management console (voipctl) for run-time server administration
Detailed logging
CSV style CDR (Call Detail Record) logs
Dynamic framework for multiple call-catching algorithms to co-exist together
Dynamic Shared Object Modules (DSOM) for loading of third party voice codec modules at
runtime.
Users can choose the best algorithm to suit their networks.
Produces audible output (.wav) for G711 (u-law) and G711 (a-law) codecs.
Output can be merged into one single file via soxmix.
You should have pcap library installed beforehand. Please
download libpcap from tcpdump.org and install it if you don't have it in your system. Please
note that most Operating Systems and Linux distributions provide this library in their
default installations.
Also, for .WAV file creation, you should have sox and soxmix tools installed. If you don't have those, please download
them from sox.sourceforge.net and
install it in your system.
Download the latest VoIPong tarball from EnderUNIX and uncompress it:
#tar zxvf voipong-version.tar.gz
There are several pre-written Makefile files in the source
directory. Examine each of them and choose the one which most suits your system. If
you're running of the the BSD type Operating Systems (i.e. FreeBSD, OpenBSD, NetBSD, Mac
OSX) copy Makefile.bsd as Makefile;
if you're using a Linux distribution then, copy Makefile.linux
as Makefile. You might need to change CFLAGS and LDFLAGS variables
accordingly:
#cp Makefile.bsd Makefile
Type make to compile voipong, voipctl and voice decoder modules:
#make
Type make install to copy compiled binaries, shared modules,
configuration files, manual pages and related documentation into the proper locations:
BSD Operating Systems (FreeBSD, NetBSD, OpenBSD, Darwin etc.) has a ports system for
easy package administration. VoIPong is a FreeBSD port, so you can install it from
FreeBSD ports tree. VoIPong is located in /usr/ports/audio/voipong directory:
Change your current working directory to /usr/ports/audio/voipong and type:
#cd /usr/ports/audio/voipong#make install clean
FreeBSD will fetch the tarball, uncompress it, compile the sources and install VoIPong
for you.
Alternatively, you can install VoIPong .tbz package with pkg_add (1) command:
Since release 2.0 upwards, VoIPong provides a powerful dynamic framework for loading
of 3rd party voice decoders into the running voipong executable at runtime. This is
called Dynamic Shared Object Modules (DSOM) Framework. Simply put, DSOM vocoder modules
are shared libraries with the .so extension. VoIPong looks for
those shared libraries in the preconfigured modpath directory,
loads them one by one. DSOM engine resident at VoIPong core, spots the initialization
method in the shared module and invokes it allowing the module to register itself inside
VoIPong runtime environment:
For security reasons, the DSOMs are expected to be owned by the same user and group
who is running the core VoIPong executable. For instance, if the user running the program
has uid 1000 and gid 10; the modules should also be owned by uid 1000 and gid 10.
The naming convention is that the modules should start with the modvocoder_ keyword, and should include the name of the decoder in
the module, followed by the .so extension. For example, the
correct name for the g711 (u-law) module can be modvocoder_pcmu.so.
There are two pre-written voice decoder modules with VoIPong release 2.0:
modvocoder_pcmu.so: g711 (u-law) decoder (payload type
0)
modvocoder_pcma.so: g711 (a-law) decoder (payload type
8)
To code and install your own vocoder module (i.e. for g726), VoIPong DSOM Decoder
Writer's Guide will be available soon.
Chapter 5. Configuration
Configuration files are all installed into VoIPong directory: /usr/local/etc/voipong. Main configuration parameters are included
in voipong.conf file. voipongnets
file maps network addresses to their proper algorithms. DSOM modules for g711-ulaw and g711-alaw (modvocoder_pcmu.so, modvocoder_pcma.so) are installed to the path given with the modpath configuration file directive.
Runtime configuration parameters vital to the smoothly operation of VoIPong server are
defined in voipong.conf, formatted as a standart .ini file. There are two sections: GENERAL for general server settings, and
FILTERS for setting up startup
filters.
logdir: specifies the log directory where voipong will save
its logs e.g. /var/log
logfile: name of the main server log file e.g. voipong.log
outdir: path where output .WAV and/or .RAW files are to be
written. e.g. /var/log/voipoutput
cdrfile: name of the CDR (Common Data Record) log file e.g.
cdr.log
networksfile: path to the network/algorithm mappings file
e.g. /usr/local/etc/voipong/voipongnets
pidfile: path to the pidfile e.g. /var/run/voipong.pid
soxpath: path to the sox executable e.g. /usr/local/bin/sox
modpath: path to the directory where vocoder DSOM modules are
installed. e.g. /usr/local/etc/voipong/modules
soxmixpath: path to the soxmix executable e.g. /usr/local/bin/soxmix
mgmt_ipcpath: path to the UNIX domain socket for management
console e.g. /tmp/voipongmgmt.sock
defalg: Default packet matching algorithm. This can currently
only be lfp. Other algorithms are to be developed. e.g. lfp
rtp_idle_time: (in seconds) when this amount of time elapses
and no RTP traffic is received for the call, the call is considered to be finished. e.g.
10
device: network device to sniff packets from e.g. eth0
promisc: set this to true 1 if you
want VoIpong to set your sniffing device to promiscious mode. e.g. set this to 1 for true, 0 for false.
mixwaves: set this to true 1 if you
want VoIPong to mix the seperate .WAV files into a single .WAV file. e.g. set this to 1 for true, 0 for false.
snaplen: maximum number of bytes to capture e.g. 1500
readtmt: specifies the read-from-device timeout in
milliseconds. e.g. 500
startup: Pcap filter string. This filter will be set during
startup procedures. To see detailed usage of pcap filters, see pcap(3) manual page. e.g.
"udp"
Sniffing out voice is a tough task. You cannot design an algorithm and expect to catch
all the VoIP calls. VoIP is relatively new and it is not a highly standardized
technology. So there have to be several call catching algorithms for various setups.
VoIPong provides a framework where you can set the call catching algorithm which you
think will best suit your VoIP infrastructure. This results in a much more specialized
and successful call sniffing.
This algorithm tries to detect calls generated via VoIP devices conforming to RTP and RTCP RFCs. This algorithm should detect and record a broad
range of calls. The most obvious advantage of this algorithm is that you'll have barely
no false positives. This is why this method is named as LFP. The #1 disadvantage will be
that this will not be able to catch calls if there are no RTCP packets or the devices do not conform to RFCs. To use
this algorithm, you will need to specify a network to use with it in your voipongnets
file.
Some VoIP devices (e.g. Grandstream(TM) IP adapters) use a fixed port to send and
receive RTP datagrams, and they do not conform to RFCs, and do not send any link control
information (RTCP packets). If you have such devices in your network, you can specify
their algorithm as fixed in the voipongnets file. This
algorithm cannot be used with networks, it can only be used with hosts, so netmask
address should always be 255.255.255.255. Please note that, after
the fixed keyword, you are expected to set the fixed port number the device is using. For
example, suppose that you have a device which uses port 40000 to
send RTP packets, you should add
this line to your voipongnets file:
LRA-SIP will follow SIP
signalling packets, and will spot the RTP/RTCP session from the SDP packets. This algorithm is not implemented yet, however I
will be working on it for the next release (probably 2.1.?)
Chapter 6. Usage
Similar to other sniffer tools at the market, VoIPong needs to get a copy of the voice
traffic you're interested in. If you're sharing a hub with one of the endpoints of the voice conversation, you
will not need to do anything, since hub devices inherently copy traffic to all its ports.
If you are in a switched
environment, some network administration will be needed. Most modern switch devices has a
handy "monitor port" which you can
use for copying traffic going through one or more switch ports. So you'll need to copy
one of the endpoints' traffic to that monitor port, and connect the computer on which
VoIPong is running. If you're running VoIPong on a gateway machine, where this machine has already access to all
the voice traffic, you will not need to do anything.
You can use -h switch to see available startup
parameters:
[murat@efe ~/voipong]$ ./voipong -h
usage: voipong [options]
options:
-h this screen
-v version info
-f run in foreground (don't become a daemon)
-d debug level. Valid levels are 0 through 4. Default: 0
-c config file path
-v switch shows VoIPong version information:
[murat@efe ~/voipong]$ ./voipong -v

You can set the debug log level by -d switch. Valid levels are
0 through 4, latter being the most
verbose. Default configuration file is /usr/local/etc/voipong/voipong.conf. You can use alternate
configuration file by issuing -c switch and providing full path
to the alternate configuration file. If you don't want VoIPong to daemonize, but instead
you want it to stay at your terminal and dump log messages to the terminal, you will need
to issue -f switch.
So, If you want VoIPong to stay at the terminal, and you want to see as many log
messages as possible, you should fire VoIPong as such:

It is strongly advised that you avoid running VoIPong with super-user, but use a
non-privileged special user created only for it. This section describes the steps you
should take to accomplish this. Note that these steps should be done after you compiled
and installed VoIPong successfully.
Create voipong user and group
#pw group add voipong#pw user add voipong -g voipong -m -s /usr/local/bin/bash
Change ownership of voipong, voipctl
and /usr/local/etc/voipong directory to voipong user:
Omer Faruk Sen has maintains VoIPong LiveCD! based on FreeSBIE project. LiveCD is an
ISO image which can be burnt into a blank CD directly, and includes pre-installed VoIPong
release along with several boot-time scripts for configuring the OS and VoIPong.
You can try VoIPong with Microsoft Netmeeting. Set up netmeeting so that it uses G711
at both ends, and make a voice call. You'll see the calls captured and wave files created
after your call finishes.
If you do not have a testbed, do not want so much pain to test VoIPong, you can replay
a test capture file in your machine and see if it is catched.
Download and install tcpreplay tool. Tcpreplay tool reads pcap capture files, and
re-injects the packets into a live network.

VOIPONG ALGORITHMS
Following release 2.0, voipong has started to provide a framework where the
user will be able to select the algorithm that will be used for a network.
This will hopefully enable the user to select the best algorithm to suit his
VoIP infrastructure, so that many more calls can be detected.
There are two currently active algorithms:
1. LFP (Least False Positive) Algorithm:
----------------------------------------
This algorithm tries to detect calls generated via VoIP devices conforming to
RTP and RTCP RFCs. This algorithm should be able to detect and record a wide
range of calls (about 70 % - 80 %).
To use this algorithm, you'll need to specify a network to use with it in your
voipongnets configuration file.
E.g.:
172.16.1.0/255.255.255.0 lfp
2. FIXED (Fixed Port) Algorithm:
--------------------------------
Some VoIP devices (e.g. Grand Stream IP phone adapters) use a fixed port to
send and receive RTP packets, and they do not conform to RFCs. If you have
such a device, you'll need to specify it in your voipongnets file:
E.g.:
172.16.1.101/255.255.255.255 fixed 40000
The number next to "fixed" keyword specifies the fixed port number the device
uses for RTP transportation.
3. LRA-SIP (Least Run Away - SIP) Algorithm:
--------------------------------------------
This algo will follow SIP signalling packets, and will spot the RTP/RTCP session
from the SDP packets.
LRA-SIP is not implemented yet, however I'll be working on it for the
next release (probably 2.1).

EnderUNIX VoIPong 2.0 INSTALL
The program is tested on
- FreeBSD 5.4
- Solaris 8
- istanbulX GNU/Linux
[1] Prerequisites
a) You should have libpcap packet capturing library installed
b) For .WAV file creation, you should install sox program
and supply sox and soxmix path in voipong.conf configuration file.
To compile VoIPong:
There are several pre-written Makefiles in the source directory. Examine each of
them and choose the one which most suits your system. If you're running of the
the BSD type Operating Systems (i.e. FreeBSD, OpenBSD, NetBSD, Mac OSX) copy
Makefile.bsd as Makefile; if you're using a Linux distribution then, copy
Makefile.linux as Makefile. You might need to change CFLAGS and LDFLAGS variables
accordingly.
After you've chosen the Makefile and copied it, type make to compile VoIPong:
# make
To install the compiled binaries, type:
# make install
and binaries will be installed at /usr/local/bin/, the configuration
file will be installed as /usr/local/etc/voipong.conf, and the algorithm
specification file as /usr/local/etc/voipongnets.
You're done. All you need to edit the configuration file, change
soxpath and device parameters to suit your system and fire voipong
$ voipong
You can connect to mgmt interface and control your server from the
interface. Use voipctl command for this purpose:
mb@efe ~$ voipctl
Connected to /var/run/voipongmgmt.sock.
Escape character is '^]'.

EnderUNIX VoIPong
VoIP call detector and voice dumper
VoIPong is a utility which detects all Voice Over IP calls
on a pipeline, and for those which are G711 encoded, dumps actual
conversation to seperate wave files. It supports SIP, H323, Cisco's
Skinny Client Protocol, RTP and RTCP.
It's been written in C language for performance reasons, proved
to be running on Solaris, Linux and FreeBSD; though it's thought to compile
and run on other platforms as well.
It's multi-algoritm framework enables users with the ability to
suit the best packet matching algorithm for their environment.
On a 45 Mbit/sec actual network traffic, it's been verified
that VoIPong successfully detected all VoIP gateways and the VoIP calls.
CPU utilization during the run has been found ranging between 66% - 80%
on a 256MB RAM, Celeron 1700 Mhz Toshiba notebook.
With it's dynamic framework for coding 3rd party voice codecs,
the current decoding capability can be easily extended.
VoIPong has been awarded the first standing by IBM Turkiye in its Linux Awards
2004 competition.
Please see INSTALL file in this tarball, and the online User's Manual available at:
http://www.enderunix.org/voipong/manual/ to compile and install VoIPong into your
system.

VoIPong TODO
* Implement "algorithm SIP" (a.k.a. algorithm lra) ,
where VoIPong will trace SIP signalling and catch calls
out of SDP packets.
* VoIPong Distributed:
Redesign and code call recording so that it can be done in a
distributed manner
* Collect call statistics out of RTP/RTCP packets.
* Better Cisco Skinny support (i.e. extract phone numbers)
* G726 codec support
Investigate further: Ignecio's mail
* G723.1 codec support

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

"Fixed Pcap-Capture-String" Algorithm
This is useful for catching dummy IP adapters, which has neither signalling
nor RTCP, RTSP, but always use fixed port numbers. In voipongnet.conf file,
the user is expected to supply a pcap filter string:
(e.g. "port 40000 and udp").

"Least False Positive" Algorithm
This will try to catch calls that are compliant with the RTP and RTCP RFCs.
Note that this algorithm was the default call-catching algorithm prior to
version 1.2 and may not catch calls that are not RFC-compliant at all.
