I have a user who wants to forward his phone to his cell phone. Normally this would be no problem.
Basically this is the scenario:
User A has an phone number of 555-555-1234
User A forwards his IP Phone to 555-555-1212.
When User B 555-555-9876 calls User A at 555-1234, the caller ID on User A's cell phone is displayed as 555-555-1234.
Is there anyway for this display the User B caller ID (555-9876) on User A's cell phone, rather than User A's number 555-1234?
I do not think it is possible when transferring off-net, as User A is the one technically placing the call. I am using the external phone mask setting on all route patterns, as well as the gateway settings "Calling Party Presentation" and "are set to "Default" and "Originator" respectively and "Redirecting Number IE Delivery - Outbound" is checked.
Current Set up:
Call Manager 6.1.2
ISDN E1 PRI on a 3800 MGCP gateway
The provider has confirmed that Caller ID is being passed
Thanks for any help!
