Important information for udp traffic

[Martinius]

Hi,

this is not really a issue, but I hope that his can save others a lot of time. If you want to use this image for the German Telekom and register/call via UDP (transport udp) use the --net=host option (or network_mode: "host" in Docker Compose) with this image! Otherwise all the AOR checks and routing will fail because Docker changes the source IP for UDP traffic to (172.x.x.x). I hope this saves someone a few weeks of their life ;) Please add it to the documentation or keep this issue open so people can find it.

Best regards
