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.
回答1:
Set the supportsGrouping, supportsUngrouping and supportsHolding properties to false in the CXCallUpdate for the call.
回答2:
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.
