dial-peer or phone or not.
- If no incoming COR list:
this means that the dial-peer or the phone can call any one. Regardless of the
outgoing COR setting on the phone called
- if no outgoing COR
list: this means that anyone can call this dial-peer or phone regardless if the
phone calling has an incoming COR set or not.
- If the incoming COR
list is a superset or equal to the outgoing COR list this means that the
call will succeed.
- If the incoming COR list is not a superset or equal to the
outgoing COR list this means that the call will fail.
- When you begin configuration first you need to configure the outgoing
COR.
- To deny a call when you configure the outgoing COR make sure that it
is a superset of the incoming COR.
