What is the Lync Mobile app? 


Using Microsoft Lync / Skype for Business, you can use your computer to interact with colleagues and contacts in various ways. But what about times when you’re out of the office or your computer and phone are inaccessible due to power supply interruptions? You can install the Lync Mobile app to your mobile device (phone or tablet) then use the device as a portable version of your office phone.

This means that you can continue to make and receive voice calls, send instant messages and emails, and even participate in video calls - as long as you have a wireless or mobile data connection.

The Lync Mobile app is available for older mobile operating systems: Android 4.0 or lower, iOS 7.1.2 or lower and Windows Phone 8 or lower. For all later operating systems, use the Skype for Business mobile app.

What are the benefits?

  • Cost of calls:
    If your IP phone is offline - for example, due to power cuts - simply use the Lync app to dial another UCT staff member's extension.
    • Free calls on eduroam:
      If you're on eduroam at UCT, calls won't cost you a cent. If you're travelling and need to phone a colleague back here at UCT, those calls will also be free as long as you're using your Lync app and phoning from a local or international university that uses eduroam.
    • Charges apply:
      If you don't have access to eduroam or free WiFi, you'll need to use mobile data - incurring your service provider's data rates - not their call rates.
    • Stay in touch when travelling:
      If you're travelling (whether locally or abroad), family and colleagues can dial your UCT office number and the call will be routed to you - wherever you are in the world. You won't need to use international roaming or pay hefty bills because these calls will be charged at local rates (i.e. Cape Town to Cape Town charges).
  • Contact colleagues easily:
    Sync your UCT contacts to the Lync app, giving you quick access to all your work-related colleagues. You can then communicate with them - either individually or in a group - via voice calls, instant messaging, email or even video calls.
  • Never miss a call:
    The app shows you any calls you may have missed, and also gives you direct access to your voicemail.
