If it's not DNS , it's a firewall... 

why don't you share us a nice trace of the call, the INVITE and the OK packets is what we're looking for. Ngrep/sngrep are great tools for you to achieve this.

Check your sip trace and makes sure clients connected over wireguard are not offering SDP over IP address that is not routable over wireguard or not even allowed over allowed-ips of wireguard client config.

Faced the same when clients connect over wireguard vpn long time ago and they used to send their public ip in the sdp body while i had no stun/turn/ice configured anywhere for the media to pass over public internet properly.

Subject: [SR-Users] Kamailio works but voice is not present during the calls!
 
Hi all,
i have a problem with my Kamailio SIP Server.
I set up a Kamailio SIP server in a virtual machine on a private network and i connect to this with a WireGuard VPN.
The problem is that i can connect to the SIP server throught different clients and users and i can call the other users, the devices ring and i can answer to the calls but unfortunatly there is no audio during the call :(
I can't understand why, it seems all si OK, a year ago i set up another SIP server with the same configuration and all works correctly with it.
Can anyone help me to understand why? I can copy and paste here all the config files if you need it.
Thank you so much in advance
Christian
