Emergency Ringdown/Hotline Service

The Emergency Ringdown or Hotline Service feature enables standard telephones to 
automatically ring a designated extension by going off-hook. Digital telephones cannot 
perform this feature, but they can receive Emergency Ringdown or Hotline Service from 
standard telephones.

Emergency Ringdown is used in healthcare facilities, where it is used 
to assist callers who may not be able to complete a call by dialing. An 
example of an incoming Emergency Ringdown call is shown on the 
right. The calling [DN] and “Ringdown” displays whether soft keys are ON or OFF.

This same feature is also known as Hotline Service and is often used for telephones in hotel/
motel lobbies.

This feature enables you to set your telephone so that you and people near your telephone can 
hear the called party over the speaker, but the called party can not hear you. You can alternate 
between parties as long as the handset is off-hook.
