IP Office Essential Edition - Basic Edition Phone Admin: Line Settings
CO Disconnect Time
Use this feature to change the disconnect time for an outside line. When a caller on hold hangs up, the local telephone company may send a special signal to the system to free the line. Different telephone companies use different length signals. The length of the signal is called the disconnect time. If you place a call on hold and the caller hangs up, but the call does not disconnect within a minute after the caller hangs up, the disconnect time is probably set too high or set at No Detection.
If the telephone company does not send a signal, keep the disconnect time set to 500 msec, the default setting. The user must disconnect a held call manually by retrieving the call and then hanging it up.
Shorten the disconnect time only if abandoned calls on hold do not disconnect.
Lengthen the disconnect time only if calls are being disconnected prematurely.
You can program and view the disconnect time for analog lines only.
