A Key Ring line rings an extension according to the settings in 2132-[01-64]: Line Ringing Stations: Config: Ring Assign: Line Ringing (2132): Ring Assignment]. 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 conditions 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 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.

Overflow for Key Ring Calls

If unanswered, Key Ring calls can route to a programmed overflow destination. The overflow destination can be an extension, Ring Group, UCD Group or voice mail. You can set up separate Key Ring overflow destinations for the day mode and at night. If unanswered at the overflow destination, the call again diverts to Key Ring. Note that a Key Ring line goes into the night mode when any extension with night mode capability presses their Night key. See Night Service / Night Ring for more.
