Sorry may be wrong forum but looking for assistance with hopefully a simple task. We have a vodavi setup with 2 outside lines coming in (1 ph # - 2 lines can ring at one time, or 2 calls out at a time or 1 of each). 1 main phone station - that all incoming call ring into, rest are extensions. I need another phone to also be able to have incoming calls ring into so calls can be answered on more than one phone. We don't have anyone with any history of the system here, but seems it should be pretty straight forward. Any assistance is much appreciated.
