Okay, with the exception of the OVLR in the DCH, we are both programmed the same way on the Nortel side. When we first set up our integration, Cisco CLIDs were not going out. I had to go into CM Admin > Call Routing > Route/Hunt > Route Pattern.
Then I clicked on each of the Patterns that handle outside calls.
(i.e. 9.1[2-9]XXXXXXXXX). I then went to the Calling Party Transformations Section and changed Calling Party Number Type to National and Calling Party Numbering Plan to ISDN. For patterns to stations on the Nortel, I set both Calling and Called Party Transformations Sections to Calling Party Number Type Cisco CallManager and CallingParty Numbering Plan to ISDN. And also remember to put the CLID in the External Phone Number Mask in the Line X on Device SEPXXXXXXXXX location.
Let me know if that helped you out
