I have a remote site that has a couple of POTS lines terminating to a FXO on the 2911. This remote site is an H.323 gateway in a CUCM 8.6 cluster. Incoming local calls for that location ring all phones at the location.
What do I need to do to enable Caller-id on these POTS lines terminating to the FXO? I am pretty sure the carrier is sending the caller ID information.
