Hi I'm looking at migrating a client away from an existing PBX and this is at the moment the only thing I can't seem to recreate on 3CX. Basically they operate under a few different names and they have a few different telephone numbers. Inbound works fine - different queues/different names displayed and there are no issues. The problem however is that they want to be able to dial out via withheld as default, or a prefix to change the outbound number. At the moment, a workaround I have done is that there are 4 extensions on the phone, each one has a different outbound called ID set, and they simply chose which one to make the call from, but, this is less than perfect and they are not too happy with it. (Also, I can't seem to get block outbound ID working, but, I am trying to work with my sip carrier on that...) Does anyone know if it is possible to do what they want on 3CX?
