Of course your right! I misunderstood the question and talked about ser's port.
In addition, if the Via header includes the "rport" parameter, then ser will send the request to the port from which the request was sent - useful for NAT traversal.

Hi!
According to the standards, this depends on the Via header field entry, which the User Agent is inserting to the REGISTER request. Responses are routed according to the topmost Via header field (every SIP hop removes its own Via header field entry). So if the User Agent has inserted a different port to its Via header field, e.g. something like
REGISTER sip:registar.xyz.ch SIP/2.0 Via: SIP/2.0/UDP 130.59.6.181:8888 From: ...The response will be sent to port 8888
If no port is specified, the default port (5060) will be used. I assume, that in SER it is implemented according to the standards. Or am I wrong...?
cheers, Bernie

If I use the port 5060 for sending REGISTER request,
response from SER
will be on the same port or on different port no..?

Or if you use force_rport(); in the ser config (ser will add rport and behave as if rport was present in the original message).

Hrm. force_rport() eh ? Can't seem to find this in the manual.

You are right, we forgot to document it. Its main use is nat traversal (together with nathelper).
