Hi, an idea I am asked a lot is why can we only choose for xx , xxx, xxxx, xxxxx number extension formats? Maybe it's an idea to make it possible to have all formats available in one system? So we can create extensions like 44, 232 and 4567 in one phone system. For bridged systems you might still make it possible that numbers starting with 9 are the bridged numbers. So no extension might start with a certain number... Thank you.
