Nobody here will be able to tell you with certitude what the problem is based on just that error.

Aside from that:

what kind of methods are we talking about here, REGISTER, INVITE?

does the request reach the proxy over TCP?

it is being relayed further over UDP?

Do the replies make it back over the same path?

Furthermore, what tcp_ setting you've got there?

Best of luck.

Thanks, that was very helpful.

But now I get an "ERROR: <core> [tcp_main.c:4070]: handle_tcpconn_ev(): connect <Client IP>:<Port> failed" displayed when trying to register.

The SIP client establishes the connection to the proxy via TCP, but does not receive an answer.

Could this indicate a faulty NAT-ALG?
