Sounds like a NAT issue.

Use STUN if the client supports it. If not, use SER's nat support.

Hello,

I want to authenticate the users that wants to make a PSTN call on every INVITE.

I have one user that can't make PSTN calls, because the message "407 Proxy Authentication Required" goes back to the wrong port (the IP is correct). I checked it with ngrep.

Has anyone of you an idea how could I fix that problem?

Thanks!

Sebastian
