Hi
I've tried without recording but I don't see anything in the logs that indicate
that the stream is being relayed. I suppose it is relaying because if I comment out the
rtpproxy related functions (force_rtpproxy) in my configuration file I don't hear
anything, whereas if they are uncommented I can hear audio. How can I troubleshoot this?
I've done tcpdump on port 7890 on my local interface and nothing is shown in the
dump.
Thanks for any pointers that help me solve my issue
Héctor

Hi!
Never did recording, but just:
1. try without recording and make sure that the stream really is relayed
via rtpproxy (tcpdump, ngrep). Your logs only show the initialization of
nathelper module, contacting rtpproxy during startup. It does not show
any call that is relayed.
2. only if above is verified and works well, add the start_recording()
command to you configuration. I think start_recording() should be called
after force_rtpproxy.

Hi everybody
I've configured a SIP server (OpenSER 1.3.2) to work with rtpproxy and
so far everything is fine, but now I want to be able to record the audio
from a conversation. I've read that this is possible by using the
function start_recording from the module NATHelper but I'm not able to
get it working
RTPproxy 1.2.1 is running with the following options:

But when I place the call no debug info from rtpproxy is being generated
nor the RTP session is being saved to file.
Any idea what the problem can be?
Thanks in advance
