| What you are looking for is in the NTP ISDN Primary Rate Interface 553-3001-369_1.00 (or more current) under Features:
Display of Access Prefix on CLID
My only problem is due to using a CLEC, all calls (local and national) come into my switch identified as E164 national, so all the local calling areas show up with 91-NPA-NXX-XXXX with this feature configured - I'm still working on a solution for that one.....
And you can enable it by TN once the RDB and CDB are set up correctly, so older digital phones don't see the codes, but the 3000s do.
Hope this helps,
