Hello all,
I am dealing with a no audio issue, phones are not even ringing. There is a private IP address in the "VIA" section of the message header of the INVITE:
Via: SIP/2.0/UDP 192.168.1.25:65291 ;rport;branch=z9hG4bKPj9e3849d1981a4094a8323dad5826ec34
and in the contact too:
Contact: sip:5002@192.168.1.25:65291;ob
In the "status 100 Attempting to connect your call" from the server, I can see the public IP of the phone under received:
Via: SIP/2.0/UDP 192.168.1.25:65291 ;rport=53990;branch=z9hG4bKPj9e3849d1981a4094a8323dad5826ec34;received=PHONE_PUBLIC_IP
And in the "status 200 ok" from the server, I have:
Via: SIP/2.0/UDP 192.168.1.25:65291 ;received=PHONE_PUBLIC_IP;rport=53990;branch=z9hG4bKPj9e3849d1981a4094a8323dad5826ec34 Record-Route: sip:SERVER_PUBLIC_IP;lr=on;ftag=9284528256a54f8b81e692133a15684c
I don't know what steps to take to resolve this issue.
The VÍA is not really a problem. Check the IP in the SDP itself. On both the INVITE and the 200 there should be IP addresses reachable by both

You need to paste the whole trace. There can be a private up VIA as long as the first VIA is an IP reachable. My point is, for audio issues, it’s not the VIA, it’s the SDP.

Hello Bonjour,
have a look e.g. to the nathelper module, the functions fix_nated_contact and fix_nated_sdp might help you here. In the default cfg you find also some more complete logic in the routes NATDETECT and NATMANAGE.
Cheers,
Henning
