An exciting update for the Lync for Windows Phone is now available, part of our ongoing, frequent releases for mobile clients. This time we’re reorganizing the settings dedicated to voice calls, making it super easy to know and control which network will be used for phone calls.
Before, you had only two options for voice calls, configured with the “Require Wi-Fi for VoIP” setting. Now that we’ve refined and renamed the two Wi-Fi options and added the Cellular option, you have three clearly defined options to choose from, each with its own advantages.
- VoIP always—The device will use a Wi-Fi connection, if available, to place the call. If Wi-Fi isn’t available, the device will defer to the 3G/4G data plan and the Lync voice calls will be initiated over that connection.
This option is perfect for those of you who always want to have the richest conversation possible, including escalating voice calls to full video and content sharing.
- VoIP over Wi-Fi only—Again, the device will use a Wi-Fi connection, if available, to place the call. If Wi-Fi can’t be found, this setting instructs the Lync mobile service to connect you using Call via Work—placing a call to your phone first, then to the destination number.
This option is excellent for those of you who don’t want the Lync call to be placed using mobile data, which depending on your service plan could be expensive.
- Cellular—The Lync mobile service will directly place a call to your phone number using Call via Work and then complete the call to the destination.
This option is the most reliable way to ensure that calls using Lync mobile don’t connect using your data plan and will be consistent when moving between networks. At the same time, it disables video and content for the call.
These three options are clearly described in the updated user interface, making it easy for you to choose the option that best suits your voice call needs.
You can select among the new options in Voice Settings:
Cellular, VoIP always and VoIP over Wi-Fi only.
One really cool thing about the VoIP over Wi-Fi and Cellular options is that when you select these settings on your phone, it updates your Lync desktop’s call forwarding option and configures it to simultaneously ring to your mobile phone’s PSTN number. This way you never miss a call regardless of the network you’re on.
If, once your phone and desktop forwarding options have been updated, you need to change to a previous forwarding state (like delegation or forwarding to voicemail), you need to do this manually in your call forwarding settings.
Finally, if you have multiple mobile phones signed in to Lync, changing your voice settings on one phone does not affect the voice settings on your other mobile devices.
