Multisite Interconnect

It would be nice that there is no need that PBX extension must be different, because if you have two PBX which both have 1xx extension range, it can recognize PBX by prefix number. That why it can be solved that PBX have same extension range and that they can be connected. So if you want to call from first PBX to second you will call 2101 for local extension 101 on second PBX and if you want to call from second PBX to first PBX you will call 1101 for local 101 on first PBX
