Your OptiPoint might not add the "rport" Via parameter (unfortunately, your net trace is not too relevant), probably unlike your other Snom and Xlite clients.
In this case, check if you have a "force_rport();" statement in you SER cfg. See a NAT handling SER sample script otherwise, for how to add it, if missing; or try tune the UA to add it, at least in REGISTERs.

Hi Michal,
Thx for the reply. It seems that there isn't such an option in the OptiPoint. But to be honest i am a little confused, because i am able to register my OptiPoint. So NAT seems to work with the REGISTER but doesn't with the INVITE.

Check whether there is configuration option "symetric signalling" (e.g. use the same port for sending requests and receiveng replies) in your OptiPoint UEa and check that to be used.
The asymetric signaling does not work when the UE is behind NAT, the port is not open for replies.
The same applies to RTP streams, you have to setup the RTP to be symetric.

Hi all,
i have a ser setup (CentOS 4.4/ser 0.9.6) with several ip phones (SNOM320 and Xlite30) and every thing seems to work fine. The ser server has a public ip address 89.xxx.xxx.xxx and the ua are behind a NAT device (corporate FW).
I want now to add some OptiPoint420 SIP but was unable to get them working. That means that the registration is ok and calls to the Optipoints from other ua (xlite or Snom) work but i was unable to place a call from Optipoint to other ua.
In the trace you can notice that the INVITE is sent to ser with Src Port 38625 and Dst Port 5060. But the response from ser is sent to Src Port: 5060 (5060), Dst Port: 5060 (5060). The result is of couse ICMP Destination unreachable (Port unreachable).
I have rtp proxy and ser running on the same server and my ser.cfg looks like the one from the SER GettingStarted http://siprouter.onsip.org/doc/gettingstarted/ch08s02.html). I read the doc about "handling of NAT using RTP Proxy" but was unable to change the config to get this scenario with OptiPoint working. Has anyone managed to get OptiPoint to work with ser?
thx in advance?
