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?

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 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.

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.
Hth,
Bogdan.

Hi Bogdan,
you are right. There is no rport in the VIA header field for the
INVITE from the Optipoint.
Via: SIP/2.0/UDP 192.168.204.5:5060;branch=z9hG4bK416072b30
But for other UA you can notice this VIA header (received and rport
parameter)...
Via: SIP/2.0/UDP
192.168.204.2:26010;received=89.xxx.xxx.xxx;branch=z9hG4bK-d87543-fb641a689c2c295f-1--d87543-;rport=64365.
i will try to use the "force_rport()" to fix this issue...
thx again for the hint.

Hi all,
as suggested by Bogdan, i try to fix my issue with OptiPoint, using
the "force_rport()" statement in my ser.cfg. I have tried several
changes but have still the same result.
I am able to register the OptiPoint...
optipoint------[Request REGISTER]------>SER
optipoint<----[ 100 Trying ]--------SER
optipoint<----[ 401 Unauthorized ]--------SER
optipoint------[Request REGISTER]------>SER
optipoint<----[ 100 Trying ]--------SER
optipoint<----[ 200 OK ]--------SER
but the when the OptiPoint sends an INVITE, the response from ser is sent to Src
Port: 5060 (5060), Dst Port: 5060 (5060) instead of the NATed port.
I use the nat-rtpproxy.5.0.cfg from the GettingStarted. Is there some
thing more i have to change in the ser.cfg.
suggestions are wellcome.
thx in advance!!!

Maybe you can send some SIP traces, a generic diagram doesn't tell too much
in this case.

Hi all,
as suggested by Bogdan, i try to fix my issue with OptiPoint, using
the "force_rport()" statement in my ser.cfg. I have tried several
changes but have still the same result.
I am able to register the OptiPoint...
optipoint------[Request REGISTER]------>SER
optipoint<----[ 100 Trying ]--------SER
optipoint<----[ 401 Unauthorized ]--------SER
optipoint------[Request REGISTER]------>SER
optipoint<----[ 100 Trying ]--------SER
optipoint<----[ 200 OK ]--------SER
but the when the OptiPoint sends an INVITE, the response from ser is sent
to Src
Port: 5060 (5060), Dst Port: 5060 (5060) instead of the NATed port.
I use the nat-rtpproxy.5.0.cfg from the GettingStarted. Is there some
thing more i have to change in the ser.cfg.
suggestions are wellcome.
thx in advance!!!

Hi Bogdan,
you are right. There is no rport in the VIA header field for the
INVITE from the Optipoint.
Via: SIP/2.0/UDP 192.168.204.5:5060;branch=z9hG4bK416072b30
But for other UA you can notice this VIA header (received and rport
parameter)...
Via: SIP/2.0/UDP
192.168.204.2:26010;received=89.xxx.xxx.xxx
;branch=z9hG4bK-d87543-fb641a689c2c295f-1--d87543-;rport=64365.
i will try to use the "force_rport()" to fix this issue...
thx again for the hint.
