RE: COR and Dial-Peer in CallManager Express

If there is ANY possible outgoing peer that can be used within the COR that
you have established, then yes, the router will try to make the call. Think
of it like routing. If you can't use one path, you will use any other path
that you see available to you in order to get to the end destination.

So if you rework your COR a bit more and further restrict things so that no
dial-peer would be matched for that pattern, then you can work it.

I have the above config. What I want is 7003 should be restricted from
calling 91212.......; but with the above config, both 7002 and 7003 are able
to call 912125251000.
If I remove the dial-peer 91, then 7003 is not able to call 912125251000;
and 7002 is able to call which desired.
 
In the first case, it looks like when 7003 dials 912125251000, the router
sees that it cannot use the dial-peer 212 because of COR restriction and
uses dial-peer 91 to make the outbound call.
 
My question is, if a call is restricted by COR config, does it hunt for
other dial-peers to match and let the call progress? This is what seems
here!
