So I have a new employee and setup twinning as I would any other user. For some strange reason when I twin to his phone, his voicemail picks up the call immediately. When I call his cell phone (from the same Avaya system) it rings just fine. So weird as the phone should not see anything different? Using the latest IP Office Essential on 500v2. Tried changing mobile delay from a range of 0-3 with no luck. He has an Iphone if that helps? Not sure if anyone else uses Iphones.
