Hello! We're using the 3CX and a Patton 4552 VoIP-ISDN-Gateway. All outgoing calls are routed through the Patton (ISDN-Lines). We are now trying to define the outgoing Caller ID (MSN, subscriber ID) anywhere but it doesn't work. We didn't find any working solution in the Pattons Web-Config or 3CX - it always uses the default subscriber ID. In the 3CX-Config we can define an "outgoing caller ID number", but without any change in the shown outbound ID. Does anybody know where the settings for defining the outgoing subscriber IDs are located? And how the have to be set in order to work? Thanks a lot.
