I'm just wondering if this is by design or not. I dialed into a VRM with an icon 600, started presenting and a few minutes later, I received a message saying "Presentation Failed to Start" and disabled the presentation button. I did this numerous times with the same result. Its a bit odd that that the presentation is sending properly but then stops which makes me wonder if this is something done by design. I haven't encountered this from an icon 800 and I leave them in calls while presenting all the time and find them left in a vmr's still presenting for long durations. I will do some further testing with some of my other 600's but I thought I would ask first.
