On a CUCM where all numbers are globalized to E.164, I run into the issue of having third party devices (Ascom DECT phones) that do not support the plus. For most things, this is not a problem.
However, when a call comes in to a E.164 DN with calling number also in E.164, and then is forwarded to the DECT phone using CFW NoAn, the calling number is sent in E.164 format as well. Since the phone strips the plus, it cannot be dialed back (from example the missed calls list of the phone).
I'm trying to find a way to change the calling number to prefix 000 which would also work for dialing out,but only to the DECT devices. Any ideas where I could manage this?
