Key Ring
Description
A Key Ring line rings an extension according to the settings in system programming. Multiple extensions
can be enabled to ring immediately or after a programmed delay for each incoming line call. In addition,
under certain conditions other types of outside calls divert to Key Ring if unanswered. The following condi-
tions also initiate Key Ring:
❥ Direct Inward Line
An unanswered DIL diverts to Key Ring if unanswered at the extension to which it is terminated. See
Direct Inward Line (page 42) for more.
❥ Hold
Calls left on Hold too long recall the extensions that initially placed them on Hold. If still unanswered,
they divert to Key Ring.
❥ Park
Calls parked in orbit recall the extension that initially parked them. If unanswered, the call diverts to
Key Ring.
❥ Transfer
An unanswered Transfer recalls the extension that initially transferred it. If still unanswered, the line
diverts to Key Ring.
Operation
Key Ring is automatic for those extensions programmed to receive it.
So they are not forgotten, unanswered calls automatically ring co-worker’s extensions.
