2400 IMX r11 Trunk to Trunk Caller-ID

[TheLaw]

I am Cisco IP Specialist who is planning an integration with a 2400 IMX r11 PBX. I am not familiar with this PBX. I am advised that there are muliple NEC systems connected via T-1 Tie Trunks in a hub or star formation (all Tie's point back to the main 2400). Currently, the design is such that caller-ID information is not passed accross the trunks.

As far as we have been told, the reason for the not passing caller-ID is that some of the remote locations are separate business units. Calls coming accross are displayed with the business units Main caller-ID number. I have also been advised that there is a "global" setting on the 2400 that turns "on" or "off" caller-ID from remote sites.

The Cisco CallManager Integration will incorporate CallCenter functionality that includes data dips into a CRM package allowing for screen pops in a helpdesk environment. The trigger is the calling number, so, we would require caller-ID information to be passed accross either a T-1 or PRI link (the two systems will be in the same closet). Is there a way to allow caller-ID to be passed from business unit "A" accross their Tie to the 2400 and then back out another Tie using 4-digit (or x-digit) dial and to our Voice Gateway?

The Cisco side will accept T-1/PRI QSIG but not CCIS. If you require any additional information, please ask. (I can't provide much from the NEC side, however)

Thanks.

Even if this was possible aren't you ignoring the customers main requirement just to try and get your box to work? If the customer wants to treat some business units as seperate entities how are you going to perform that once you have satisfied the requirements of your box?

Allow me to clarify (after re-rereading my post, it does not appear clear). The customer does not allow calls out to the PSTN to pass caller-ID of the extensions (just the main number is published). Currently, calls are not made from business unit "A" to "C" via "B". "B" Currently contains the helpdesk. This is being outsourced to "D" (if that makes sense - "B" is the main hub and "A" and "C" are peripheral. "D" is being introduced to manage the helpdesk. This is not my decision, this is how it is being done. It is my job to facilitate this.

Part of this, I have also found out, is going to be hampered by the fact the Toll Fraud mechanisms do not even allow trunk-to-trunk calling - i.e. - "A" cannot call "C" so this also has to be addressed since "D" is going to appear as another "hub" since all business units need to communicate with it. Trouble is, the only way (currently) to access the Campus Area Network)

So, in a nutshell:

1) Can I pass caller-ID of extension out 1 TIE line but publish only the main number out of another?
2) Can I initiate trunk to trunk 4-digit dialing but only to site "D"?

Thanks
