Some of the features of the app as described in the windows store are:
- View colleagues’ availability in real time and select the best way to communicate – initiating an instant message (IM), email, voice or video call.
- Connect to Lync Meetings with a single touch, without requiring long numeric passcodes or conference numbers.
- Forward or simultaneously ring calls to your Enterprise Voice (Lync ID) number so you’ll never miss a call.
- Lync 2013 for Windows Phone provides transport layer security (TLS) and perimeter/internal network protection without requiring a VPN, so your communications experience is safer no matter where you are or what network you use.
