sip connection from cs1000 to sipex or aterisk

[irvjam]

I have been trying to connect sip foundry (sipex) to our cs1k.
I am able to call out from sipex to cs1k, unable to get calls from cs1k to sipex server. I have noticed others with the same issue using asterisk.

I have the sipex server gateway pointing to our node tlan ip address (not the NRS) for outgoing calls - This is working.
I've have NRS with a static gateway endpoint to sipex with routing entries - This is not working.

I see the calling information in sipex using their internal CDR with the cs1k CPND and extension number, but the calls are failing.
It's like the call setup information is working just not able to negotiate the connection.

If you say that the call is reaching the SIPEX that means that the NRS is doing its job and sending the call to the correct endpoint.

Check codecs and payload you have enabled in the SS and the SIPEX.
