Microsoft made a lot of announcements at the Lync conference this week.
First up, it's adding an Android tablet Lync client to the iOS, Windows Phone and Windows clients that are already available. It's also bringing voice calls and large meetings to Lync Online.
Elsewhere it's letting businesses offer free Skype calls to customers, and letting you make HD video calls from Lync to Skype or to legacy video conferencing systems like Tandberg.
