[Freeswitch-dev] Recoding G729 raw payload in FreeSWITCH and G729 decoding

I was just thinking about something like this the other day. My idea  
was to record calls as pcap files for debugging purposes. The ability  
to play back an RTP stream from within a pcap file could be very  
useful for reproducing customer issues. You could either record one  
RTP stream per pcap or stuff both streams into the pcap, and possibly  
even the sip signaling. I've used sipp to play back pcap files in the  
past to reproduce polycom bugs. You must give it a pcap file  
containing a single rtp stream.
