CLID from CCM thru Nortel 81C to PSTN?

[Telco01]

Posted this on the Nortel forum and figured I would try here as well.

Can I get the called party to see the DID number of the Cisco phone connected to the Nortel 81C with a PRI connected to the outside world via PRI? We want to display the DID # of each Cisco phone or a pre-determined number set for the Cisco Phone profile in CCM.

Make sure that you are either masking the desired caller id on the route pattern transformation mask OR mask it individually on the phone and have the "Use Calling Party's External Phone Number Mask" checked in the desired route patterns.
Not much more on the cisco side. You have to make sure you allow that to go through on the nortel side and be masked by the system of course.

If you turn on D Channel monitoring on the Nortel, do you see the information going accross the PRI you want to see? That should at least tell you which side has the issue and where to start looking.

Had similar CallerID issues between Mitel & Cisco CUCM 8x to the PSTN. As I faintly recall the intermachine PRI trunks had to be H.323 with a gateway router in the middle for it to work. MGCP had all kinds of weird callerID problems.

Addt'l info....
This was during migration moving 1700 users incrementally from the Mitel to the Cisco. The mistake we made was in moving the PSTN trunks last, *after* the migration rather than before or at the start. Had we moved the PSTN trunks first it would have created CallerID issues on the Mitel, but the problem would solve itself as users migrated over to the new platform.
