Cisco CM 8.5 integration with Nortel 61C rls 25.40 caller ID manipulation problem
I have a very specific problem with a Nortel option 61C rls 25.40 integration with a Call Manager rls 8.5 and Unity Connexion. Systems are integrated by way of PRI routes between the Nortel and the CM. I am looking for a way to manipulate the caller ID of a call originator on the Nortel PBX so that Unity and CM see only 4 digits.
The customer's setup is as follows :
All the phones are on the Nortel PBX, with voicemail split half and half between Call pilot and Unity. When calling to CM from a Nortel phone, Nortel PBX sends 7 digits as caller ID, being extension number followed by a suffix of three zeroes. We've tried to have the Nortel PBX send only 4 digits (by changing the call type in NARS) with no luck because of lack of software packages CDP and QSIG.
Now, In CM, I've built Calling transformation patterns CSS that I've applied on the Device pool, so that when a Nortel Phone calls a Softphone on CM, the display shows the correct 4 digits caller ID, but on no answer calls redirected to Unity still push the 7 digits caller ID, hence creating confusions for users that hear info on caller with 3 zeroes at the end and not permitting features as message reply or callback.
Is there a way, in CM, that I can get to manipulate the caller ID of the caller beyond the cosmetics of the Calling transformation patterns?
