They should just ditch all of their efforts to try to make Skype or Lync working and either start it over or acquire a company that can do voice/video calls and text chat reliably like WeChat for example. Skype is such a tragic product that I can hardly believe that anybody would using it in a corporate environment if it wasn't MS who were pushing for it. One interesting question that comes up in my mind: is group voice calling a really hard problem to solve? At this stage I am much more likely to use a simple phone conference than Skype because it works just so much better. Curious what others think.
