Hi there, I am about to start a project where I will be providing the phone lines for a new suburb and need to provide a phone system to handle the calling via voip delivered by fibre optic cable to each house. However i cannot figure out how to set 3cx to use 7 digit extensions. I need to set it so that if a user dials their neighbour 929-9082 it will call their extension, rather than go out their trunk to the pstn exchange and back in through their neighbours trunk. If they dial a 7 or more digit number that is not an internal extension, then it needs to go out their trunk to the pstn exchange to be connected. Eg. if they dial 929-9083 which is not an internal extension, it needs to go to the pstn to be connected to a recipient somewhere else. Is it possible to do this with 3CX? I really dont want to have to learn trixbox or asterisk. I have got 3cx working as an office pbx and it works really well - would be awesome if i could use it for this project also. We are assigned random 7 digit numbers from the wholesale voip provider. 3CX is hopefully going to be used to act as a mini exchange so that calls around the suburb dont need to go through the trunk lines and save bandwidth to the voip provider and then return back in another trunk again.
