Coverage
these types of receivers are unavailable or not programmed does the call go to
another, more impersonal type of Group Coverage—either the QCC queue or a
calling group (including a voice messaging system calling group).
A call to a sender that is also ringing on Primary Cover, Secondary Cover, and/or
Group Cover buttons rings until answered (or the caller hangs up). When the call
is answered, the ringing and flashing green LED are removed from all other
telephones providing coverage for the sender. However, when a calling group is
programmed as the receiver for a coverage group, the ringing and flashing green
LED are removed from the sender’s telephone as the call leaves the calling group
queue and is sent to an available calling group member. (A call on a personal line
button on the sender’s telephone is an exception. The ringing and flashing green
LED remain on that button until answered, either by the sender or by a receiver.)
NOTE:
The duration of the ringback heard by an outside caller is shorter than the
actual ring heard at an MLX or analog multiline telephone. Therefore, an
outside caller hears one or two rings and may also hear the number of
rings programmed for the Coverage Delay Interval plus the number of rings
programmed for the Delay Ring interval. For example, if the Coverage
Delay Interval is programmed for one ring and the Delay Ring interval is
programmed for two rings, an outside caller hears four rings before the call
begins ringing at receivers’ telephones. If both intervals are set to their
maximum values, the caller can hear up to two additional rings.
A call goes to Group Coverage depending on the following conditions:
■
Whether the sender is available or unavailable
■
Whether the sender has Individual Coverage (Primary Cover or Secondary
Cover buttons programmed on other extensions) and, if so, whether an
Individual Coverage receiver is available
■
The type of Group Coverage receivers programmed:
— Only Group Cover buttons on multiline telephones
— Both Group Cover buttons and the QCC queue
— Only the QCC queue
— Only a calling group
■
In Release 4.1 and later systems, the Group Coverage Ring Delay is set
for each sender’s extension. When Group Coverage is used in conjunction
with Individual Coverage, calls should ring at receivers for Individual
Coverage first. Consider the following factors before setting the Group
Coverage Ring Delay for an extension:
— If a sender has only Primary Coverage and any receiver’s Primary Cover
buttons are set to Delay Ring, make sure that the value for the Group
Coverage Ring Delay is higher than the Primary Cover Ring Delay value
for each sender.
