Call blocking difficulty

Hello,

We are using OS version 10.12.6 and xcode version 9.2.For call blocking, we have tried two different method : call Directory Extension Delegate


addBlockingEntry and addIdentificationEntry, but did not get success with any of them.

By using addBlockingEntry, output:


<CXCallDirectoryExtensionContext: 0x10541e590> - UUID: 008E60D0-B1AA-48AF-9683-268585F0E3CD - _isHost: YES

_isDummyExtension:NO

inputItems:

By using addIdentificationEntry, output:

<CXCallDirectoryExtensionContext: 0x10541e590> - UUID: 008E60D0-B1AA-48AF-9683-268585F0E3CD - _isHost: YES

_isDummyExtension:NO

inputItems:

So i haven't been able to find a solution, looking for your help in the matter.

Thanks
