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:
283K 2009-07-06 13:41
1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;1.a.rtp
275K 2009-07-06 13:41
1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;1.o.rtp

1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;2.a.rtp
0 2009-07-06 13:41
1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;2.o.rtp
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.

I'm looking at RTP Tools [*], but I don't expect they will be useful
for it. However, I get segmentfault when using "rtpdump" command XD

Hi, Iñaki....
In an automatic way, I'm looking also...
As an exercise, I used Wireshark.... it could identify the flows, but
that's it... I also didn't find a way to extract the audio...

Of course, I cannot use Wireshark in a production environment for
recording hundreds of calls a day XD

I think that I find a useful link:

Right now I can't test it, but seems a good path...

Really interesting, thanks a lot.
However, it requires "rtpproxy version 1.2" ¿?¿?¿
My version is the trunk version:
~# rtpproxy -v
Basic version: 20040107
Extension 20050322: Support for multiple RTP streams and MOH
Extension 20060704: Support for extra parameter in the V command
Extension 20071116: Support for RTP re-packetization
Extension 20071218: Support for forking (copying) RTP stream
Extension 20080403: Support for RTP statistics querying
Extension 20081102: Support for setting codecs in the update/lookup command
Extension 20081224: Support for session timeout notifications
And I cannot see "-P option" ¿?
Thanks.

Ok, tested.
The CVS trunk version is, of course, >= 1.2 and includes the -P option
(even if doc says nothing).
I've tryed the above solution (using rtpbreak) and works nice.

Great news...
You hit the point... RTPProxy is really a great peace of software, but
the same can't be said about it's documentation... :(
Well, at least this procedure is now tested and (why not?) could be
described in the Wiki...
