7. API Conference Call Scenario Main Application thread PK_CONF_Initialize(tApplicationConfiguration config) // Initialize system PK_CONF_Start() // Start the system PK_CONF_CreateConference//Create a conference A Call is triggered from the CO App Conf Event Thread PKX_SYSTEM_WaitOnEvent is triggered and BaseEntity::HandleQueueEvents determines a new call member needs to be created and handled Call::handleIncomingCall Call::answerCall -> Channel::handleConferenceCall->playRequestForConfNumber This will prompt the caller for the Conference member. The state machine Channel::m_channelConfState is used to track the different states to validate the call Play Conference Prompt Gather conference digits Play PIN Prompt Gather PIN digits Play Name Prompt Record Name Play Entry Tone or Greeting Once in the conference, the caller can press the digit “5” to toggle between mute/unmute. After the second participant enters the conference will start being recorded. Once the conference reaches 1 member, the recording will stop.

8. API Conference Call Scenario (...) Main Application thread PKZ_CONF_MuteMembers // Mute all members in a particular conference PKZ_CONF_UnmuteMembers // Unmute all members in a particular conference PKZ_CONF_Stop() // Stop the system PKZ_CONF_Cleanup // Cleanup the system
