A maximum of eight Primary Cover and Secondary Cover buttons can be assigned to provide Individual Coverage for a given sender. Only one Cover button for each sender can be programmed on a multiline telephone.
A maximum of eight Group Cover buttons can be assigned to provide Group Coverage for each coverage group. All eight can be programmed on one multiline telephone, or the Group Cover buttons can be distributed on as many as eight multiline telephones.
A receiver with a multiline telephone can have as many as eight Cover buttons, which can be programmed for any combination of Group and Individual Coverage.
If a receiver has both a Primary Cover or Secondary Cover button for a sender and a Group Cover button for the group of which the sender is a member, a call for the sender rings only at the receiver's Primary Cover or Secondary Cover button. This prevents multiple deliveries of the same call to the same receiver.
Each coverage group can have any number of members, from none to all the extensions in the system.
Each sender can be a member of only one coverage group.
If a sender without Individual Coverage is a member of a coverage group and no receivers are assigned for the group, a caller hears ringback instead of a busy tone when the sender is unavailable.
If a Calling Group is assigned as a receiver for a coverage group, it is the only receiver for that group; no other types of Group Coverage receivers can be programmed. Individual members of the coverage group, however, can be senders to Individual Coverage receivers.
A Calling Group can be a receiver for up to 30 coverage groups.
A receiver with a Group Cover button can also be a member of the coverage group for which the button is programmed. Calls to that receiver are sent to all other receivers programmed for the group.
When both the QCC queue and multiline telephones are programmed as receivers for a coverage group, the QCC queue is not counted in the 8-receiver maximum for the group.
A QCC cannot be a coverage sender.
When Group Coverage is the only type of coverage programmed for a sender, the QCC queue should not be programmed along with Group Cover buttons on multiline telephones. Because the QCC cannot be programmed for Delay Ring, eligible calls ring immediately both at the sender's telephone and at the QCC queue. This may not allow the sender enough time to answer the call before a QCC operator answers.
If a call is sent to coverage because the sender does not have a button available to take the call, the call does not return to the sender's telephone, even if a button becomes available while the call is ringing at a coverage receiver's telephone.
An inside voice-announced call made on an SA Voice or ICOM Voice is not covered. If it is converted to a ringing call--for example, because the sender's speakerphone is in use--the ringing call is sent to coverage.
No type of Cover button can be used to make calls.
When the sender also has Individual Coverage and an Individual Coverage receiver is available, the Delay Ring interval is used as an delay in addition to the Coverage Delay Interval before a call goes to Group Coverage.
Non-local UDP calls (Hybrid/PBX mode only) are treated as outside calls by the system and by Selective Coverage features: Coverage Off, Coverage Inside, and Coverage VMS Off.
When no principal user is assigned for a Personal Line, calls received on the Personal Line cannot be forwarded to outside telephone numbers. Calls follow the Individual Coverage patterns of all senders who share the line and the Group Coverage pattern of the extension with the lowest logical identification number (lowest numbered jack on the module).
Coverage delay settings affect the ability of Integrated Administration to program some Coverage options for AUDIX Voice Power.
Night Service Coverage Control, when enabled through system programming (factory setting is Disabled), controls VMS coverage only and has no effect on Individual Coverage (Primary or Secondary) or on other types of Group Coverage. When disabled, the feature has no effect whatsoever on coverage.
In a system with Night Service Coverage Control enabled, Night Service transitions do not toggle the programmed Coverage VMS Off button to the opposite status. Instead, when Night Service goes on or off after a user has manually pressed the button, the button follows Night Service status just as other programmed Coverage VMS Off buttons do. The status of programmed Coverage VMS Off buttons is always set to match the most recent user press or transition into or out of Night Service operation. For more information see Night Service.
