Hi, we've this situation:
office A with 6 extensions with numbers: 2XX
office B with 12 extensions with numbers: 4XX
I have to prevent that office B make calls to own internal extensions (4XX). It can make only external calls or to office A extensions?
To best explain:
extensions 4XX must call only external or 2XX numbers, but not 4XX.
Is this possible?
(I know that i can solve via dial plan on the phone, but i would know if this is possible on the pbx).
Thx!
