8.16.3 Leaving or Ending a Conference
When going on hook, there are two different situations:
In this case, the conference will be ended for all participants if you put the handset on the hook.
If you put the handset on the hook, you will leave the conference. A goodbye signal will be produced for all other subscribers and the remaining subscribers can continue to speak to one another.
All those subscribers whom you added to this conference will leave the conference with you. The conference will continue for all other subscribers.
To leave a conference
Requirement: Another subscriber started the conference.
To end a conference
Requirement: You started the conference.
If Subscriber A of the original conference added other subscribers, e.g. B and C, to this conference, a second conference between A, B and C will continue to exist until Subscriber A, as initiator of the second conference, terminates the connection and thus ends the conference.
