With an existing conversation instance, audio can be added or removed.

Add audio to a conversation

conversation.audioService.start().then(function () {
	// Successfully added audio to the conversation
});

Remove audio from a conversation

Conversation.audioService.stop().then(function () {
	// Successfully removed audio from the conversation
});

Subscribe to changes from the audioService in a conversation

An event is fired when the client has successfully added audio to the conversation, or another participant has invited the client to add audio.

  1. Subscribe to the event.
conversation.selfParticipant.audio.state.changed(function (val) {
…
});
  1. If the val argument in the previous snippet indicates the event is an invitation to add audio, the client may reject or accept the invitation.
if (val == 'Notified') {
  if (confirm('Accept incoming audio request?')) {
      console.log('accepting the incoming audio request');
      conversation.audioService.accept();
      console.log('Accepting incoming audio request');
  } else {
      console.log('declining the incoming audio request');
      conversation.audioService.reject();
  }
}

Accept video and send video automatically

Calling videoService.accept() in response to an audio invitation does nothing. Calling videoService.accept() in response to a video invitation will accept the audio and video and start its own video as well.

  1. Subscribe to the audio state changed event.
conversation.selfParticipant.audio.state.changed(function (val) {
…
});
  1. If the val argument in the previous snippet indicates the event is an invitation to add audio, the client may accept the invitation while also sending their own video in Skype, as follows.
if (val == 'Notified') {
conversation.videoService.accept();
}

Mute a conversation

The client may temporarily mute their own audio in the conversation.

// Toggle muting the client's audio
conversation.selfParticipant.audio.isMuted.set(!audio.isMuted());

Put a conversation on hold

The client may also place itself on hold, temporarily pausing all incoming and outgoing audio.

// Toggle placing the conversation on hold
var isOnHold = conversation.selfParticipant.audio.isOnHold();
conversation.selfParticipant.audio.isOnHold.set(!isOnHold);
