I have a cisco 2821 router as voice gateway with an IOS version 12.4(3f). This router has an EVM-HD-8FXS/DID module and 2 EM-HDA-6FXO cards. I have connected an analog phone on the FXS port 2/0/1.
I type the following commands:
and the dial-peer:
dial-peer voice 6888 pots
I create a route pattern on my CCM 4.1.3
Now the analog phone can communicate with the IP phone and vice versa.
My problem is that I want to restrict the calls from the analog phone, for eg I don't want analog phone to call the numbers beginning with 7. How can I configure the router for this purpose ?
Can someone help me ?
