Hi Florian @florian-h05
I have installed your webrtc-sip-gw in combination with your oh-sipclient. So far everything is working fine. I am just struggling with one thing:
I’d like to setup your intercom solution in a way that it is working internally (within your own network at home) and externally.
Unfortunately Fritz Box is not able to override “external” hostnames/domains (intercom.whatever.com) by local ip adresses. Furthermore I like to avoid adding more complexity by adding another DNS-server.
Do you have any ideas or what did you do?
Hi Oliver,
getting it working “outside” your network will be super tricky. Actually, I think the FritzBox will be the smallest challenge, the bigger challenge is the WebRTC transport that is based on UDP. While webrtc-sip-gw provides a WebSocket to communicate with the SIP server and do the signaling, the actual media transport is UDP-based and uses a wider-range of ports.
I do not recommend opening those in your firewall.
What I’ve done and what I would also recommend you is to setup WireGuard VPN (all recent FritzBoxes have a WireGuard server integrated), super easy, performant and oh-sipclient behaves as if you were at home.

Hi Florian, works very good so far. Did you have any issues with echo cancellation? I setup the intercom in full-duplex mode which provides horribly echoes. My camera (mobotix) isn’t obviously capable enough to filter out echoes.
Did you face similiar issues?
My DoorBird does a good job at echo cancellation, no issues so far.
