I have 3 cordless Mitel DECT 112 phones part of a ring group, x1000. The three phones (1001, 1002, 1003) are all set to ring at the same time. Since the 112's are part of a ring group they are not able to show a message waiting indicator if a voicemail is left in the ring group. To get around it I created an overflow point to a desk phone, x1004, and set up a voicemail for that and changed the call rerouting to go to voicemail but it never triggers.
What I am trying to accomplish is to have a MWI when a call comes into x1000, either for the ring group or for the desk phone. Any help here would be appreciated.
