Inbound Caller ID Reformatting
When a user calls in the PBX, the trunk provider may send a caller ID that is inconvenient for you to redial directly.
In this case, you can reformat inbound caller ID based on a trunk. The caller ID will be reformatted before it is sent to the called party.
For more information, see Reformat Inbound Caller ID based on a Trunk.
