ChannelHangupRequest

Base type: Event

A hangup was requested on the channel.

ChannelHangupRequest 에는 몇 가지 의미가 있다.

Soft 가 true 로 설정되었을 때는, Hangup() application 이 실행되었거나, Dialplan 에서의 h extension 이 실행되었을 경우 발생한다. h extension 은 명시적으로 지정될 수 도 있고, 묵시적으로 실행이 될 수 있다. 따라서 한번 Dailplan 으로 인입된 Channel 이 종료될 때는 이 이벤트를 발생시킨다.

Soft 가 false 이거나 설정되어 있지 않는 경우는, Hangup Request 를 명시적으로 받았음을 의미한다. ```channel hangup request``` 명령어나 상대방쪽에서 BYE 메시지를 먼저 보냈을 경우가 이에 해당한다.

하지만 뭔가 규칙이 일정하지 않다. ARI 에서 ChannelHangupRequest 이벤트를 사용하고자 할 때는 주의가 필요하다.

    "soft": {

2016-05-09 15:00 +0000 [205a31f86c]  Mark Michelson <mmichelson@digium.com>

	* Expand the scope of Dial Events

	  Dial events up to this point have come in two flavors
	  * A Dial event with no status to indicate that dialing has begun
	  * A Dial event with a status to indicate that dialing has ended

	  With this change, Dial events have been expanded to also give
	  intermediate events, such as "RINGING", "PROCEEDING", and "PROGRESS".
	  This is especially useful for ARI dialing, as it gives the application
	  writer the opportunity to place a channel into an early bridge when
	  early media is detected.

	  AMI handles these in-progress dial events by sending a new event called
	  "DialState" that simply indicates that dial state has changed but has
	  not ended. ARI never distinguished between DialBegin and DialEnd, so no
	  change was made to the event itself.

	  Another change here relates to dial forwards. A forward-related event
	  was previously only sent when a channel was successfully able to forward
	  a call to a new channel. With this set of changes, if forwarding is
	  blocked, we send a Dial event with a forwarding destination but no
	  forwarding channel, since we were prevented from creating one. This is
	  again useful for ARI since application writers can now handle call
	  forward attempts from within their own application.
