Have an install, that's very very simple. Basically has DID's for each extension, and a main number that is pointed to ring group 8000. Ring group 8000's strategy is ring all, 15 seconds, and then connect to a voice-mail if no one answers. All of this works just fine, except if one of the users has their status set to something other than available. If one of the users goes to away, and say that away forwards calls to their cell number, then when the main number is called, the call gets forwarded to the cell, and does not ring the rest of the phones. What would cause this?
