Method Detail

providerDidActivateAudioSession

default void providerDidActivateAudioSession(CXProvider provider,
                                             AVAudioSession audioSession)

Called when the provider's audio session activation state changes.

providerDidDeactivateAudioSession

default void providerDidDeactivateAudioSession(CXProvider provider,
                                               AVAudioSession audioSession)

providerExecuteTransaction
```
default boolean providerExecuteTransaction(CXProvider provider,
                                           CXTransaction transaction)
```
Called whenever a new transaction should be executed. Return whether or not the transaction was handled: - NO: the transaction was not handled indicating that the perform*CallAction methods should be called sequentially for each action in the transaction - YES: the transaction was handled and the perform*CallAction methods should not be called sequentially If the method is not implemented, NO is assumed.

providerPerformAnswerCallAction

default void providerPerformAnswerCallAction(CXProvider provider,
                                             CXAnswerCallAction action)

providerPerformEndCallAction

default void providerPerformEndCallAction(CXProvider provider,
                                          CXEndCallAction action)

providerPerformPlayDTMFCallAction

default void providerPerformPlayDTMFCallAction(CXProvider provider,
                                               CXPlayDTMFCallAction action)

providerPerformSetGroupCallAction

default void providerPerformSetGroupCallAction(CXProvider provider,
                                               CXSetGroupCallAction action)

providerPerformSetHeldCallAction

default void providerPerformSetHeldCallAction(CXProvider provider,
                                              CXSetHeldCallAction action)

providerPerformSetMutedCallAction

default void providerPerformSetMutedCallAction(CXProvider provider,
                                               CXSetMutedCallAction action)

providerPerformStartCallAction

default void providerPerformStartCallAction(CXProvider provider,
                                            CXStartCallAction action)

If provider:executeTransaction:error: returned NO, each perform*CallAction method is called sequentially for each action in the transaction

providerTimedOutPerformingAction
```
default void providerTimedOutPerformingAction(CXProvider provider,
                                              CXAction action)
```
Called when an action was not performed in time and has been inherently failed. Depending on the action, this timeout may also force the call to end. An action that has already timed out should not be fulfilled or failed by the provider delegate

providerDidBegin
```
default void providerDidBegin(CXProvider provider)
```
Called when the provider has been fully created and is ready to send actions and receive updates

providerDidReset
```
void providerDidReset(CXProvider provider)
```
Called when the provider has been reset. Delegates must respond to this callback by cleaning up all internal call state (disconnecting communication channels, releasing network resources, etc.). This callback can be treated as a request to end all calls without the need to respond to any actions
