Cannot make calls in Microsoft Lync 2010 app Device: Sony X10a
Android: 2.3.3

Can the Microsoft Lync 2010 app on the play store make calls?

I can login to my office365 lync account and send messages, but the phone icon is greyed out.

Is voice not avilable on Android, or am I doing something wrong?
Lync 2010 has support for calls:


  Lync 2010 for Android extends the power of Lync to your mobile device
  – including rich presence, instant messaging, audio conferencing, and
  calling features from a single, easy-to-use interface.


However, you will need to check with your IT Department if it has been enabled for your account.
