Ringdown Extension, Internal / External
• Description
With a Ringdown Extension, a user can call another extension, outside number, or
Abbreviated Dialling 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 phones, 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 interval. Depending on the setting of this interval, the extension user
may be able to place other calls before the ringdown goes through.
The system allows each extension in the system to have a Ringdown Extension. All
extensions can share the same Dialling number, if desired.
Conditions
A. Ringdown extension has no effect on an extension’s current (active) call.
B. The Ringdown Extension user must lift the handset for ringdown to work.
Default Setting
Disabled.
