Hi All, I hope you can help. We have a set of three engineers who rotate their out of hours on-call duty on a weekly basis. Previously we had an Asterisk-based phone system and we simply created a ring group (mapped to a certain DDI) which dialled mobile numbers on a prioritized hunt. I can see a way to get 3CX to do similar - I can create the ring group with prioritized hunt, but I can't seem to put in external numbers to ring - only extensions, and then forward to one number. Is there a better way to do what I'm trying to achieve? All help is greatly appreciated. Thanks, Verta.
