I have run into a Vantage 12 in the field and they want to add lines!! I have no idea how to do this!(I was told it was close to a Norstar..it isnt close!) I guess if somone can tell me if the Vantage supports more than 3 lines, how to program the thing,(I figured it supports 12 extensions, but does it have voice mail capabilities)?? Any help would be appreciated...And in return I can help with a Norstar/BCM question?
