Skype for Business (Lync): Mobile App Connects As Audio Only

It has been reported from some Microsoft Skype for Business (S4B) users, that when joining a Pexip Cloud Virtual Meeting Room (VMR), that they connect as an audio-only participant.

The Pexip Cloud Service offers VMRs as a Cloud-based bridging resource to bring multiple video and audio participants together to collaborate.  Capable of supporting multiple video-enabled communities, a VMR can interwork call-in participants using standards-based H.323/SIP video devices, web browser based users, and Microsoft Skype for Business users.  For more information on using S4B with Pexip Cloud VMRs, please review the article Skype for Business (Lync): Using on the Pexip Service.

Microsoft Skype for Business users can choose from a variety of platforms and clients including Windows/Mac Desktops, iPhone/Android SmartPhones, and iPad/Android Tablets.  While Microsoft continues to refine the end-user experience so that the various software clients have a common look and feel, care should be taken to understand default settings which are present on the mobile device versions of S4B that may result in unexpected behavior.

As video calls are expensive in the amount of data used to support real-time video and audio traffic, S4B Mobile Apps default to audio-only calling when the connectivity is not Wireless LAN (WiFi) based.  The result of making an S4B call to a Pexip Cloud VMR, when the connectivity is 3G/LTE then, is that the call does connect but there is no video, only audio.  This had led to some confusion and the belief that there is a technical issue with the VMR.  To change this behavior, the S4B Mobile App simply needs to be configured to permit video calls while not on WiFi.

Follow these steps on the S4B Mobile App to disable the requirement for WiFi connectivity:




The steps described above should be sufficient to resolve the issue.  If the problem persists, contact Pexip Technical Support for assistance.
