回答1:

you can use Cellular Call States for this purpose

CTCallStateDialing

The call state, before connection is established, when the user initiates the call.

CTCallStateIncoming

The call state, before connection is established, when a call is incoming but not yet answered by the user.

CTCallStateConnected

The call state when the call is fully established for all parties involved.

CTCallStateDisconnected

The call state upon call termination.
