I have setup CME 4.1 with a cisco 7940 ip phone in dual-line mode. I am using vonage as my PSTN line which connects to my FX0 card on voice-port 0/0. When I am on the phone I hear the beeping noise from call waiting but do not see the indicator on my phone nor do I see caller-id although caller-id works when the phone is not busy. I've been reading through Cisco and google and have tried many ways for configuring the ephone-dns but none seem to work.
The phone setup is as follows: Since the 7940 is a 2 button phone I assigned the first button to my extension and the 2nd button to the main line extension. The setup I used for call waiting was:
button 1:3 2c1,2 button 1 gets ext. 1003 and button 2 gets ext. 1001 and 1003. This still did not work. Any help would be greatly appreciated.
