Disable Add Call option from CallKit

Question

Is there a way to disable Add Call option from Callkit when receiving a VoIP call?

I couldn't find any api to disable this. But WhatsApp disabled this feature.

Answer 1

You need to set both supportsGrouping, supportsUngrouping and supportsHolding properties to false in the CXCallUpdate, and set maximumCallGroups and maximumCallsPerCallGroup to 1 in your CXProviderConfiguration.

Answer 2

Set the supportsGrouping, supportsUngrouping and supportsHolding properties to false in the CXCallUpdate for the call.
