I do have a similar setup and encounter the audio problem

My Kamailio sits behind a router listening to the public ip sip port 5060 and use internal lan ip to communicate with other service, Asterisk. Rtpproxy and WITH_NAT are set up according to instruction.

However, I notice when kamailio communicates with Asterisk (which is on the same LAN subnet), a lan IP is passed to Asterisk.My sip client on outside public network does not receive any audio stream.

Is it wrong with the Kamailio setup?

Hello,

if the users are behind nat, install rtpproxy and enable WITH_NAT in default config file. Read the comments at the top of kamailio.cfg to see how to set the control socket for rtpproxy.

Cheers,
Daniel

Hello,

I just installed Kamailio for the first time 4.2 on Debian Wheezy. Everything went alright, I created two users, both can register and make calls, but with no audio.

So the problems are:

1. No audio

2. I want to setup Kamailio as Outbound Proxy

3. I wish to have this proxy with TLS support.

Please suggest solution
