Operation
The disconnect command forces a call to disconnect. Any previously established call treatment ends when the disconnect command is executed and the call is removed from vector processing and from Communication Manager.
If the call is connected to a station while the announcement is playing, the announcement stops and the caller hears ringback. Also, because vector processing stops when the call connects to a station, the disconnect portion of the command is not processed.
When the disconnect command includes an announcement, Communication Manager sends answer supervision just before the announcement plays.
When the disconnect command does not include an announcement, Communication Manager sends answer supervision before disconnecting a call.
Note:
Answer supervision is not sent for ISDN trunks.
