CCIS to QSIG interworking "Calling Name"

[AntBan]

Hello,
We have a CCIS network of about 10 NEC 2400IPX and 2400IMS systems. We recently acquired a Cisco Call manager to use at a remote site. We have connected the Cisco CM to our HQ 2400IPX using QSIG trunks and all features work as expected (Calling name, Calling number, connected name/number, call back etc..)

The issue is when the call hops off to a third node via the CCIS trunks. The called user does not get Calling name they only get calling number.
Example:

CCM---QSIG----IPX2400---CCIS---IMS2400 r5

When a user on the CCM calls a user on the IMS2400 platform the calling name is not presented to the called phone but we know the name is being delivered to IPX2400 from the CCM because if the call is for a IPX platform user the calling name appears on the IPX phone.

I've made sure OAI is turned on on the IMS side, and if user on IPX2400 calls user on IMS2400 the calling name does appear. It seems to be a QSIG to CCIS interworking issue. Has anyone done this type of integration and seen this? Is their a config change that can fix it?

Thank You
AntBan

The only config change I can think of is replace the Cisco and / or the person who purchased it! Why screw up a 10 system IP capable network for one remote site?

I second that Ozzie! Our company is in the same situation and looking to get rid of the Call Manager and Cisco Unity Voicemail Server.
