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:
root@openser:/opt/rtpproxy-1.2.1/bin#
ps uax | grep rtpproxy
rtpproxy

When I start OpenSER I see the following in

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
