How to transfer a inbound call and keep origination caller ID?

[Anonymous]

We have a customer that wants to keep the originating caller ID when transferring inbound calls outside the PRI?

This is typically a function of the PBX. If you haven't programmed a caller-id override on the trunk and the carrier permits it, it should just work if the PBX preserves the original caller-id on transferred calls.
