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

The default behaviour is that ser listen and sends on the same port:
Register
your client ------------> ser (port 5060)
200 OK
your client <------------ ser (port 5060)

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