Unity Connection not passing CallerID to CUCM over SIP Trunk

I'm trying to get CallerID working for Unity Connection Device Notification (and it seems everything else), however, when I run UC Remote Port Status Monitor and the Call-Out goes to CUCM for the Device Notification, no caller ID is presented to the CUCM SIP trunk.

06:06:02, New Call, CalledId=,  RedirectingId=,  Origin=16,  Reason=1024,  CallGuid=, 
CallerName=,  LastRedirectingId=,  LastRedirectingReason=1024,  PortDisplayName=LFC_CUCM-1-134,
[Origin=Unknown],[Reason=Unknown]
06:06:02,
Dialing '99254753'

06:06:32, Idle
06:06:33, Idle

Therefore, the out-going call to the PRI PSTN is:

10:59:01.005: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8  callref = 0x5B03

        Sending Complete
        Bearer Capability i = 0x8090A2
                Standard = CCITT
                Transfer Capability = Speech
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA98397
                Exclusive, Channel 23
        Calling Party Number i = 0x0081, N/A
                Plan:Unknown, Type:Unknown
        Called Party Number i = 0xC1, '9254753'
                Plan:ISDN, Type:Subscriber(local)
*Dec  6 10:59:01.513: ISDN Se0/0/0:23 Q931: RX <- CALL_PR

I've looked through my SIP trunk on the CUCM side and for Inbound Calls, Connected Line ID and Presentation Name are set to "allowed" or "default" doesn't make a difference. RTMT Port Status also shows no "caller", so I'm thinking there is some way to set or allow the calling number on the Unity Connection (8.5) side.

Oddly enough, I also noticed that in Unity Connection> Telephony Integrations > Port Group, if I change the Contact Line Name from nothing to "Unity" (or whatever), the Q931 debug outbound doesn't show ANY "Calling Party Numer - = XXXXX" and the carrier throws out the BTN as the ANI.

10:46:00.837: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8  callref = 0x5AFF

        Sending Complete
        Bearer Capability i = 0x8090A2
                Standard = CCITT
                Transfer Capability = Speech
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA98397
                Exclusive, Channel 23
        Called Party Number i = 0xC1, '9254753'
                Plan:ISDN, Type:Subscriber(local)

Any ideas on where/how CallerID comes from, on Unity Connection with a SIP integration?

THANKS!!

Mike.

Did you ever find a solution to this one?

I did not- my work around has been to put in a name for Contact Line Name under Port Group Basics Switch configuration in Unity Connection- this for some reason keeps CUCM from sending ANI TYPE/PLAN information in the Q931 message, and my carrier then sends a default ANI of the circuit's BTN. When I have time, I'll open up a TAC ticket.
