Ringdown Extension (Hotline), Internal/
External
Description
With a Ringdown Extension, a user can call another extension, outside number, or Speed Dialing
number by just lifting the handset. The call automatically goes through - there is no need for the user
to dial digits or press additional keys. Ringdown Extensions are frequently used for lobby telephones,
where the caller just lifts the handset to get the information desk or off-site Reservation Desk.
After the Ringdown Extension user lifts the handset, ringdown occurs after a programmable time.
Depending on the setting of this time, the extension user may be able to place other calls before the
ringdown goes through.
This feature can also be used as an off-hook alarm application. For example, if a patient in a care
facility fails to return the handset to the cradle, it routes to a care givers station after a programmed
time.
This feature is sometimes known as a Hotline.
Conditions
• Ringdown extension has no effect on an extension current (active) call.
• The Ringdown Extension user can lift the handset or press
Speaker key to initiate ringdown.
• If the Ringdown/Hotline destination is a speed dial bin, the appropriate service code must precede
the bin number.
• Ringdown Extension can use Speed Dial - System/Group/Station numbers (and follow their trunk
routing) as the destination number.
• Ringdown Extension follows Call Forwarding. For example, the ringdown destination can forward
their calls. When the Ringdown Extension user lifts the handset, ringdown automatically calls the
extension to which calls are forwarded.
• If the Ringdown Extension user hears busy tone when they lift the handset, they can Camp-On to
the destination, leave a Callback or activate Off-Hook Signaling.
• The ringdown destination user can activate Do Not Disturb. When the Ringdown Extension user lifts
the handset, they hear DND. If enabled, the Ringdown Extension user can override the destination
DND.
• If the destination extension has Handsfree Answerback enabled, the call voice announces. If the
destination extension has Forced Intercom Ringing enabled, the call rings.
• A Virtual Extension can be a ringdown destination. This would allow a front door key to be
programmed on every extension.
• Delayed Ringdown can occur by setting the Hotline Start Timer. However, Ringdown does not occur
if the Hotline Start Timer is set longer than the Extension Dial Tone Timer.
• The @ code is used to make an outbound call automatically forward to a DISA Trunk or to VM Auto
Attendant. This code can be used only on ISDN outbound calls. Internal calls and analog outbound
calls are not supported.
