since a few weeks we have an issue now, that when users with Office 2013 \ Skype for Business 2015 connect to a LifeSize Cloud Meeting their own video freezes after about 10 Minutes. Audio still passes and they can still see the other participants moving, but on the other participants site the video of the Skype for Business 2015 user is frozen. After disconnecting from the meeting and re-connecting the video transmission works again for about another 10 minutes, then it will freeze again. We've tested this already on different computers in different sites and different Skype for Business users and the problem always shows up. So it's quite easy to reproduce. We've also opened a ticket at LifeSize support and the technician saw the issue himself and pulled some logfiles to analyse. So far, there seems no solution for this problem, yet. (Except updating to Office 2016\Skype For Business 2016, but that's not the solution we need) I wanted to ask if someone else is experiencing the same problems?
