Emergency Ringdown
If a station remains off-hook for a programmable period, it can be automatically
treated as an Emergency Call and directed to an emergency destination. The station
may have partially dialed a number or have dialed no digits at all. Each station is
programmed with its specific emergency ringdown destination.
A station number or a group pilot number can be specified as an emergency ringdown
destination. In a private network, the station or pilot number must be in the same
network node. Remote emergency destination and door phones are not permitted.
Override Calls
The available override features are:
Busy Override
Ring Over Busy Override enables you to send a muted ring tone to a busy station to
indicate a call is waiting. The Busy Override (BOV) muted ring can be programmed
for each station to be two muted rings only or continued muted rings until the call is
answered. This option applies to the station receiving the muted ring. The muted ring
can be sent to the telephone speaker or to the telephone handset/headset and speaker.
