How would I block certain number ranges (example: 900/976 numbers) on outgoing POTS dial peer using 36xx gateway. Can COR be used in routers other than AS5800? Is there any other way to do this other than using COR? There is no Call Manager involved in this scenario.
COR is supported only on the Cisco AS5800 access server.
The Class of Restrictions (COR) feature provides the ability to deny certain call attempts based on the incoming and outgoing class of restrictions provisioned on the dial peers. This functionality provides flexibility in network design, allows users to block calls (for example, to 900 numbers), and applies different restrictions to call attempts from different originators.
Please refer to the following threads on similar lines.
You can try doing this. I have not done this myself , but am planning to test it in the lab now.
Option 1 : Create a dial-peer that matches the block pattern and do not specify any sesion taget. That should generate a route unavailable state for that call.
Option 2: Create a dial-peer that matches the block pattern. Identify a dummy loopback interface on the same router for the session target. Shut down this loopback interface explicitly. This should also stop the call.
Options 3 : Create a pattern , map it with a num-exp to a not existant dial-peer . This should do our job as well.
mmm... all this is theoritically speaking. Lemme test this in tha lab and willlet you know.
