UC, Lync 2013, Manage VoIP settings in Lync 2013 for Windows Phone

On this page you will find information to help you decide which connection settings to use in Lync 2013 for Windows Phone.


The first time you sign in to the Lync app, you’ll need to decide whether you want to make Lync audio and video calls using Wi-Fi only, or use your cellular data connection when you’re not connected to Wi-Fi.

 NOTE:    To make changes to your call options, from the My Info screen, tap the More (…) icon, and then tap Settings.

Here’s what happens when you make your selections.

Require Wi-Fi for VoIP: Off

  • Lync might use your cellular data connection to make and receive audio calls when you’re not connected to a Wi-Fi network. If you are connected to Wi-Fi, Lync tries to use the Wi-Fi network for audio calls instead.
  • If you’re not connected to Wi-Fi when you make an audio or video call, Lync calls you back at the number you specify. For these calls, you’re connected to the audio portion of the Lync call only. Video isn’t available for that call. This might result in usage of your mobile voice plan minutes.
