I have a 5 Slot carrier with the 8.0 is center slot and Mail VS in Slot 2. I can reach the Mail VS by dialing 777 but I can't seem to get the right extensions into Hunt Group #7. If I program 28 & 29 incoming calls get intercepted and the "call is being transferred to receptionist" announcement. I've tried programing extensions as far down as 21 and high into 30's and still the same thing. Do I need more slot filled in the carrier move Mail VS to another slot? I have a 206EC module I could plug in if it would help. Really scratching my head on this one.
