Re: [OpenSER-Users] OpenSerand RTPProxy, no RTP audio

Hi Robert, I placed a call from 2.3 to 2.5(gail) to observe the traffic. Then I place a call from 2.3 to gail(a)2.10 to observe the traffic through openser. For the network topology, it's all on the same local network. I tried the default cfg file and it works fine. I'll try adjusting nat_uac_test, as it's not recognizing I'm on the local network. All set, Thanks! -----Original Message----- From: Robert Dyck Sent: Thursday, February 14, 2008 9:49 PM To: users(a)lists.openser.org Cc: Eric Phetteplace Subject: Re: [OpenSER-Users] OpenSerand RTPProxy, no RTP audio The pro's seem to be busy so I'll give it a go. If gail == 2.5 then a call from 2.5 to gail does not make much sense but maybe it was a typo. You did not say anything about your topology. Where were expecting to find the RTP packets? uac test 19 ( really 16+2+1 ) maybe isn't really what you want. Check the nathelper documentation. Among other things it will check for a private address. If you have local to local calls, there is no NAT involved. Sending the RTP through a proxy is unnecessary. It probably would work though.
