How to disable CallKit integration for Skype for Business iOS

Summary

Skype for Business iOS is integrated with CallKit version 6.10 and later versions.

CallKit API with iOS 10 enables Skype for Business (SfB) calls to work the same way as the native calling experience on iOS, allowing you to seamlessly extend your personal device as a business phone.

CallKit integration lets you do the following:
  • Answer Skype for Business calls with a single swipe from the lock screen, just like on a cellular phone call.
  • Have uninterrupted business conversations with the ability to choose between Skype for Business and a cellular call.
  • Initiate Skype for Business calls directly from the native call log, where CallKit integration registers SfB calls.

Resolution

Disable CallKit integration for a tenant

A tenant administrator may set the AllowDeviceContactsSync policy to false.
Required: November 2016 Update for Skype for Business Server 2015

Set-CsMobilityPolicy -Identity site:Redmond -AllowDeviceContactsSync $False 

Disable CallKit integration for a single user

A user can disable CallKit integration on their device by tapping their avatar, selecting Settings, and then toggling Mobile Integration to off (default is on). This cannot be done if CallKit is disabled for the user's tenant.
