Call coverage is used to redirect all intercom, transferred, DID and outside calls on lines assigned to you to another extension. When call coverage is in use, covered calls are routed to the covering extension after a specified number of rings set by the system administrator.
•Group calls, forwarded calls, transfer-return calls and calls to doorphone alert extensions are not covered.
•A single extension can cover multiple extensions, however an extension can have only one covering extension.
•If you activate call coverage at your extension, for calls on a line appearance button, you still can intercept a call rerouted to coverage by pressing the button.
•You can program call coverage on a programmable button. Use a button with lights if you want a visual indication when your calls are being covered. When the button indicator is on, your calls are being covered; when off, call coverage is not active.
•If both call coverage and do not disturb are on, covered calls go immediately to the covering extension without ringing the covered extension. Similarly, if call coverage is on and a call begins to ring, you can turn on Do Not Disturb to send that call immediately for coverage.
•If an extension has call coverage and VMS Cover active, calls ring at the covering extension.
•If the covering extension does not answer, the call is routed to the voice mailbox of the covered extension after the specified number of VMS Cover Rings. If the covering extension has Do Not Disturb active, the call is routed immediately to voicemail.
•If an extension has call coverage active without voice mail coverage, covered calls ring at the covering extension for the specified number of call coverage rings. Outside and intercom calls continue to ring at the covering extension until the call is answered or the caller hangs up.
•For transferred calls, if the covering extension does not answer, the call goes to the transfer return extension after the specified number of Transfer Return Rings (if VMS cover is not active).
•Call forwarding override call coverage. If an extension has call coverage and call forwarding active, calls are routed to the call forwarding destination extension.
