Restrictions with internal calls

[AntonyB93]

Hello all,

I'm trying to configure COR, but the main problem is that I'm unable to restrict calls between local CME phones because calls aren't going over dial-peers. I'm unable to find answer if it's possible to set COR list on DN only, not on the dial-peer? If it's possible maybe you could tell we which feature could do this?

Hello, Vivek,

Thank you, very much for that. But the problem is that this explains only how to configure COR per dial-peer (between two routers). I'm able to do that. But the problem is that I'm unable to set COR for DN's in the same CME (when call isn't going over dial-peer).

Example:
There are 2 Routers (R1 and R2).

R1 has 2 DN's configured (1000, 1001)

R2 has 2 DN's configured (2000, 2001)

With standard COR lists I'm able to restrict calls from 1000 to 2000 and 2001, because they are going over dial-peers. But I need to restrict calls to from 1000 to 1001.
