I have a 2811 gateway with FXO ports in which I have plugged in a regular analog POTS line in one port. I am using Cisco UCM v6.1 on the backend for call processing.
Since I have call waiting service from the Telco, I would like to configure it so that caller ID shows up on the call waiting call on the incoming FXO port.
Currently, caller ID only shows up on the 1st call, but I only hear a "beep" when the 2nd call comes in--there is no caller ID.
Is there a workaround for this? It is an H.323 gateway.
Please let me know when you can.
