Automatic Release
Description
Automatic Release drops the line circuit when an outside party abandons the call. For this feature to
work with Loop Start Trunks, the CO/PBX providing the outside line must provide a timed disconnect
signal. Automatic Release is normally provided on Ground Start, DID and ISDN trunks.
Conditions
•
Automatic Release on ISDN trunks is provided by the protocol.
•
When an outside line is accessed using a dedicated line key, the LED associated with the line key
goes off when Automatic Release occurs.
•
On Loop Start trunks Automatic Release is only available on incoming calls.
•
This feature functions while a call is in progress, on hold, or in a conference.
•
This feature applies to all ICM type calls in progress, holding or parked.
•
When Automatic Release occurs and the telephone is in handsfree mode,
Speaker
automatically
turns off. If using the handset, the station is set to idle when the handset goes on-hook.
