Ringdown Extension, Internal/External
With a Ringdown Extension, a user can call another extension, outside number, or
Speed Dialing number by 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 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 interval. Depending on the setting of this interval, the extension user
may be able to place other calls before the ringdown goes through.

extension does not have a line key, the trunk rings the line appearance key. If an
extension has a key for a trunk that is not in its ring group, the trunk follows Access
Map programming.
