I'm running CUCM 7.1 and have a SIP Trunk to OCS 2007 R2. To PSTN, there is a h323 Gateway atteched to CUCM.
Calling from anywhere to anywhere works perfect. The problem is, when Office Communicator calls to PSTN, it shows not the DID number.
What I see on a wireshark trace on mediation server is, that the FROM filed does not contain a number. There is just the mailaddress of the user.
The same I see in RTMT, there is just the name of the user. On the gateway I see, that there is no calling party within h225 trace.
So, the question is, where can I set, that the number is sent to CUCM and to the gateway.
For better understanding:
OCS Server---------MediationServer------------CUCM7.1------------h323 Gateway-------PSTN
