You can set up a queue for a hunt group. When all extensions in the group are busy, calls wait in the queue for the next available extension. You set the length of the queue to determine how many calls can wait in the queue.

If all hunt group members are unavailable or the queue is full, the system treats the call in one of the following ways:

• If the call is internal or is carried on a DID (Direct Inward Dialing), DS1 (Digital Signal Level 1), or tie trunk, the caller hears a busy tone.

• If the call is on a central office (CO) trunk, the caller hears ringing, but gets no answer.

• If the hunt group has call coverage, the system sends the call to a coverage point.

You can set up a queue warning level and an associated queue warning indicator lamp. When the queue reaches this level, the lamp lights and remains lit until the queue drops below this level. You can have one lamp for each hunt group queue. Install the lamp so that all members of the hunt group can see the lamp.
