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?
