We just installed a Branch Office connecting back to our main site. The problem I have is the main site has a receptionist already who works off DN 0, the Branch office also has a receptionist so I cannot configure her as 0. (I've configured her for the time being as 8900) What I would like to do at this point is prevent the phones off my Branch Office from internally calling 0 and reaching the other office...anyone have any idea's if I can do this?
