A DLC can be both an Individual or Group Coverage receiver and a member of a coverage group.
The QCC cannot be a sender for either Individual or Group Coverage. The QCC queue can be a Group Coverage receiver for up to 30 coverage groups. Because Cover buttons cannot be programmed on the QCC, the queue is not counted in the 8-receiver maximum allowed for each coverage group. The QCC cannot be an Individual Coverage receiver.
The QCC queue priority and the individual QCC operator who receives calls for each coverage group are assigned independently for each group.
If a line/trunk is programmed to ring in the QCC queue and also is assigned as a Personal Line on a telephone that is a member of a coverage group covered by the QCC queue, a call on that line/trunk does not appear as a coverage call at the QCC.
If Group Cover buttons are programmed for a coverage group in addition to the QCC queue, and all QCC operators are in Position-Busy mode, a Group Coverage call goes to all receivers except the QCC queue.
When Group Coverage is the only type of coverage programmed for a sender, the QCC queue should not be programmed in addition to 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.
When the QCC queue is assigned as a receiver for a coverage group and a call transferred to a group member is not answered, the call returns to the queue as follows:
If you assign a Coverage button of any kind to a line button without LEDs, the only visual indication that the button is active is on the display.
Other Multiline TelephonesAny type of multiline telephone can be a sender and/or receiver for either Individual Coverage or Group Coverage and can have up to eight Cover buttons.
A 4400, 4400D, or single-line telephone can be a sender for either Individual or Group Coverage. A 4400, 4400D, or single-line telephone can be a receiver for Individual Coverage. It can be a receiver for Group Coverage only when it is a member of a Calling Group assigned as a receiver for a coverage group.
Transferred calls to a busy 4400, 4400D, or single-line telephone are not eligible for coverage unless Coverage Inside is on. A transferred call to a busy single-line telephone with Group Coverage and Coverage Inside off camps on at the single-line telephone and returns to the originator, if not answered before the transfer return interval expires.
