Create a URI Scheme for Skype for Business supported by all clients
The skype: URI is a great and easy way to start an audio or video call, create a conference and sending instant messages, and can be used in Windows, IOs and Android. There is nothing a good as it for Skype for Business.
The ms-sfb:// URI scheme seems not to work on Windows 10 mobile.

Especially the ?call&video=true option!
