[Kamailio-Users] Recording RTP session

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.
regards
