I have a phone that is in a public area which is meant to only be used for calling a few numbers as posted next to the phone. Is there a way in VitalPBX 4.5 to actually block all numbers not in a list.
You can achieve this by creating a special Class of Service with its own Outbound Routes.
However, if you don’t want to create new Outbound Routes, you can use the Dialing Restriction module.
