> But you do raise valid points. I work in an organisation that loves Microsoft and store-bought solutions like Skype for Business.

Is the situation any better elsewhere? On windows at work we constantly have issues with desktop sharing over skype freezing and have to fall back to WebEx and deal with it's sound not working properly, we'll often end up with a hybrid of voice calls on skype and screen sharing with webex and all the wasted time dealing with that. I had an hour long meeting on WebEx yesterday where I could barely hear anyone.

These aren't things I've tried to do on linux so I can't comment on how well supported they are, but let's not pretend they work seamlessly in the microsoft world either.
