data carving layer 7 RTP RTCP SIP VoIP
VoIP SIP RTP
This tutorial shows the capabilities of the plugin voipDetector. It displays troubleshooting information of SIP/RTP/RTCP and is able to carve RTP content.
Preparation
First, restore T2 into a pristine state by removing all unnecessary or older plugins from the plugin folder ~/.tranalyzer/plugins:
t2build -e -y
Are you sure you want to empty the plugin folder '/home/wurst/.tranalyzer/plugins' (y/N)? yes
Plugin folder emptied
Then compile the core (tranalyzer2) and the following plugins:
t2build tranalyzer2 basicFlow voipDetector txtSink
...
BUILD SUCCESSFUL
If you did not create a separate data and results directory yet, please do it now in another bash window, that facilitates your workflow:
mkdir ~/data ~/results
The sample PCAP used in this tutorial can be downloaded here:
Please save them in your ~/data folder.
Now you are all set for analyzing VoIP traffic!
voipDetector
This plugin was originally designed for troubleshooting of telco VoIP communication, therefore RTCP is also decoded which provides additional statistics to the basicStats plugin, such as packets lost and maximal jitter reporting.
Data carving with voipDetector
The configuration listed below, allows the user to enable the RTP content save mode, the length of SIP names in the flow structure, the path where RTP content is saved and the default name as a prefix if no file name can be found.
We also added an configurable offset in the payload of RTP, for special purpose applications.

...For now we switch on VOIP_SAVE=1 and keep VOIP_RMDIR=1 as we like t2 to delete
the files between experiments to remove clutter. RTCP decoding stays off as there is not much
to troubleshoot in our pcaps and we like to put an emphasis to the data carving capabilities
of t2.
Use t2conf, recompile and engage t2 on the MagicJack pcap with the packet mode.
t2conf voipDetector -D VOIP_SAVE=1 && t2build voipDetector

The end report tells you that RTP, SIP are detected and he found 2 voice comms being written to your /tmp/TranVoIP/ directory.
tawk -V voipStat=0x0385The voipStat column with value 0x0385 is to be interpreted as follows: bit | voipStat | Description ============================================================================= 0 | 0x0001 | RTP detected 2 | 0x0004 | SIP detected 7 | 0x0080 | RTP marker 8 | 0x0100 | RTP content write operation 9 | 0x0200 | SIP audio RTP flow announced
Note that there is no RTCP detected, as it is switched off. First look at the flow file, you see the flows labelled as SIP, or RTP, certain SIP, RTP parameters and the names of extracted content.

...In order to listen to the content you need to convert to e.g. .wav format.
Note that the encoding format G711. indicates that the raw stream is mu-law compressed.
Just use ffmpeg which does a fine job.
cd /tmp/TranVoIP
ls
nudel_2a173650_8_A_G711u.raw nudel_31be1e0e_8_B_G711u.raw

If you use a player such as vlc, then in nudelA.wav you hear the caller
and in nudelB.wav the callee.
In order to see some RTCP output, switch switch it on and recompile
t2conf voipDetector -D VOIP_RTCP=1 && t2build voipDetector
Now try this pcap sip_sjphone_conf.pcap
and execute t2 on it including packet mode.
... -------------------------------------------------------------------------------- voipDetector: Aggregated voipStat=0x0387 voipDetector: Max number of file handles: 1 voipDetector: Number of SIP packets: 60 [66.67%] voipDetector: Number of SDP packets: 21 [23.33%] voipDetector: Number of INV packets: 20 [22.22%] voipDetector: Number of BYE packets: 8 [8.89%] voipDetector: Number of unique SDP audio address, port: 12 [13.33%] voipDetector: Number of RTP packets: 16 [17.78%] voipDetector: Number of RTCP packets: 14 [15.56%] -------------------------------------------------------------------------------- ...
And the end report tells us, there is indeed RTCP and 4 voice comms with some packet loss. The extracted content is written to the /tmp/TranVoip directory, but as configured the directory is erased before writing.
tawk -V voipStat=0x0387The voipStat column with value 0x0387 is to be interpreted as follows: bit | voipStat | Description ============================================================================= 0 | 0x0001 | RTP detected 1 | 0x0002 | RTCP detected 2 | 0x0004 | SIP detected 7 | 0x0080 | RTP marker 8 | 0x0100 | RTP content write operation 9 | 0x0200 | SIP audio RTP flow announced
In the flow file you will see that there are many RTCP types being detected, and jitter info was conveyed.
