Update the properties of the specified conference.
The statusCallbackUrl (specified upon creating the Conference) is invoked whenever a Conference is emptied or terminated. Participants are automatically disconnected. When updating the Conference status to terminated, no other attributes can be set (alias, playBeep) and FreeClimb returns an HTTP 204 response with no body.
Once a Conference is terminated, FreeClimb will not reuse the conferenceId.
