We have a version of it installed. It doesn't work in any meaningful way.
If I work from home on a corporate device (all MS end to end) can I use Skype for business to call into the office? Nope doesn't work.
We have Mitel IP phones on desks in the business. I ask "can we replace these with Skype for Business thus having (in theory) a universal comms system with IM, Video and calls?"
'Yes' is the answer, except it's too expensive due to MS licensing.
I do wonder just WTF is the point of half the stuff MS peddles these days.
