Receive PBXNSIP call not working in Communicator

[Marcel V]

I have sucessfully implemented the OCS connection in one direction (OCS -> PBXNSIP)

 

Now i can not get the direction PBXNSIP extension towards OCS to work.

 

It each time tells me it can not find a trunk ?? The OCS Gateway trunk is configured.

 

The logging shows me this:

Hello Marcel,

 

did you following the guide in the pbxnsip-wiki? http://wiki.pbxnsip.com/index.php/Office_C...ications_Server

 

In your trace is a strange switch from tcp to udp. I can't see, whats causing this. Did you add a static registration with transport=tcp to your pbxnsip accounts?

 

btw: whats your pbxnsip version?

 

Best regards,

 

Jan

HI Jan,

 

Yes i followed the ocs stuff. It works from OCS to an PBXNSIP extensie but not the other way around.

 

Yes i add an static registration with transport=tcp to my pbxnsip account

 

The version is: 3.0.1.3023 (Win32)

 

By now we suddenly can't even call from OCS to pbxnsip (this after i added one user with the same functionality ?)

 

I have to inform you we are using TLS towards the OCS clients

 

If there is anything you like me to try of log please let me know, any help is very appreciated.

 

Thanks,

[Vodia PBX]

I have to inform you we are using TLS towards the OCS clients

 

AFAIK OCS is strict on the certificates in TLS. The PBX uses just a default certificate, and probably OCS does not like it. In order to get things working I would start with TCP first. Then if that works you can try using TLS and you might have to import a valid certificate (and the respective private key).

Ok we will try to start with TCP which is difficut for us due tohe fact we are testing with an external OCS hoster on TLS. I believe TCP is only allowed if internally used.

 

Another question:

 

When i call from OCS to an XLITE client the XLITE client rings, i pickup, XLITE tells me CALL Established but OCS tells me connecting call and that's it. No connection. Any feedback on this ?

We have changed this to TCP and this is the result:

 

We do not have OCS ringing but this is the LOG:

That might be a problem. Maybe that usse agent tries to be smart and there is a router in the path that does not support (too) smart devices. In other words, don't use STUN.

 

The TCP/TLS timeouts are probably okay, because the PBX initiates those connections and they are not kept alive with registrations.

Hi Marcel,

 

the OCS Enterprise Voice Integration has nothing to do with TLS or Certificates (regarding OCS 2007 R1, R2 is another special story).

 

In R1:

 

The connection between OCS Mediation Server and a Voip-PBX or VoIP gateway is Sip over TCP (no Certs no SSL) + Standard AudioCodecs (Mediation Server translates the MS RTA to e.g. G711)

 

Please do not change the OCS default TLS, SRTP security settings, especially for pbx integration tests. It is completly unnecessary !

 

You are using a OCS hoster. Please describe the details of the infrastructure! Where is the mediation server placed? At your location, next to pbxnsip on the same subnet???

 

For troubleshooting: please install Snooper from the OCS Resourcekit on your Mediation Server !

 

Best regards,

 

Jan
