we have around 250 lines exchange
100 of them setup with 3 digit DNs 111
and the rest are programmed 5 digit 35555
3 digit intercoms have all the facilities as 5 digit numbers however they can not receive calls from outside the network
i want them to setup something like
if an outside caller dials a specific code and then intercom extension to receive call for example code 40 - 111 and local area numbers will dial 111 without code
secondly i want to restrict intercoms dialing outside the network so they can only dial local network and opertaor
