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.

The tags already indicate this is about iOS. There is no need to add "iOS" to the title. — Léo Natan, Oct 21 '16 at 18:20

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.

This should be the accepted answer. It should be noted, though, that this configuration also hides the "hold-and-accept" option with call-waiting. It also prevents you from supporting any other functionality (like "assisted transfer") that depends on placing a call on hold. There doesn't seem to be a permutation of `CXProvider` / `CXCallUpdate` settings that _only_ disables the "add-call" button. If someone does know a workaround I'd be most grateful :) – Reid Oct 04 '17 at 17:04

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

Actually this is not enough. You also need to set `maximumCallGroups` and `maximumCallsPerCallGroup` to 1. The answer below should be accepted. – user1256821 Nov 11 '16 at 12:56
Can I open my custom app on answering the VoIP phone call? Please know me since I don't have iOS development experience. But curious to know this. – Choxx Jan 19 '17 at 11:14
