 /**
  * The Conference Redirect event is fired whenever an existing conference is modified via a POST request made to the /conferences/{conferenceId} endpoint. The response may be either empty or a BXML document. Only the following verbs are valid for conferences: PlayAudio, SpeakSentence, StartRecording, StopRecording, PauseRecording, ResumeRecording. Audio verbs will be heard by all members of the conference. Recordings capture audio from all members who are not muted or on hold, as well as any audio verbs that are played into the conference.
