[Kamailio-Users] RtpProxy: start_recording()

[Iñaki Baz Castillo]

Hi, I'm using start_recording() function of nathelper module. I use
"-R" option in rtpproxy daemon in order not to record RTCP.
start_recording() is called in route and onreply_route.

After the call ends I see the following files in the recording directory:

Some questions:

- "1.a.rtp" is one direction and "1.o.rtp" the other, right?

- What are the last two files (0 size)?

- How to extract the audio from these files? note that the used codec
could be G729, ALAW, GSM...

Thanks a lot.
