Post VoIP analysis with Xplico
Hi,
I wanna know how I can get some audio files like Xplico uses, in order to check its quality and try them with my VoIP analysis application.
And I also wanna know what Xplico´s version lets me to extract the wav audio files from the RTP packets. When I try to open them with Xplico, Flash Player opens but it doesn´t show anything.
Thanks in advance.

The rtp audio "stream" is decoded by the SIP dissector or by the RTP dissector. If RTP streams are part of SIP VoIP call then the audio contents are decoded by the SIP module otherwise by RTP module. We are development MGCP (completed), SKINNY ans H323 dissectors and all these dissectors can decode the RTP stream associated with them.
SIP and RTP dissectors (and all others) to produce mp3 file generate (at an intermediate stage) a wav file (one for caller and one for called), but this wav file is removed.
if you want to listen the wav files the steps are these:
  • from SIP or RTP dissector, change NO_DEBUG_RM from 1 to 0
  • with xplico in CLI, you can find wav files in tmp/xplico/sip or tmp/xplico/rtp dirs
  • with xplico from XI, you can find wav files in /opt/xplico/pol_*/tmp/xplico/sip or /opt/xplico/pol_*/tmp/xplico/rtp directories

Ciao.
