I have CME 4.2 on a 2851 with a PRI to local carrier. Have a limited amount of DID's on the PRI, so only about half of the dn's are associated to a DID. For those that are not, the caller ID passed to the carrier is that of the internal extension and the local user name for that DN, which is not acceptable since some of those numbers are that same as private sector phone numbers. Is there a way to mask a group of related DN caller Id from calls on internal numbers, so that when they go across the PRI, they get changed to a common name/number, but retain thier normal internal/name when making in house calls?
The problem with manipulating names is that requires a custom tcl/iver script incoming to each ephone-dn and that opens up a lot of issues in itself.
You can remove the name altogether with:
interface serial x/y:23
no isdn outgoing display-ie
So the best way would be to ask telco to overwrite calling name for all calls.
Thanks for the nice rating and good luck!
