Hello 3CX Community, I am trying to install a 3CX combined with a Patton 4120 Gateway. The problem I have is that all incoming calls on DID numbers ending on the default central number e.g (000). I tried to type in all DID's with the prefix for it self, also no succes. But I can not set only two digits in the field, even when the 3CX and the patton send that on SIP the number in two digits. ISDN BRI. It would be a pleasure if someone could help me.
