SBX IP 320 Features & Operation Guide

CO Line Queuing

When a Station user receives a busy tone during an attempt to access a CO Line, the user may

request a call back (queue call). The station will receive a call back when the busy CO Line

becomes available.

Operation

To activate CO Line Queuing while receiving a busy tone:

1. Press and release the hook-switch if the station is an SLT.

2. Dial 556 or press the [CALL BK] button.

3. When the confirmation tone sounds, replace the handset.

4. Once the CO Line becomes idle, the call back ring will be received at the station.

5. Lift the handset. The CO dial tone should be heard to make a call.

Conditions

• A CO Line may have any number of queues at one time.

• When the queued CO Line becomes idle or a CO Line becomes available in the group,

the oldest queued station will receive the call back.

• A station can make only one CO Line queuing request at a time. If the station tries to

make another CO Line queuing, the previous one is canceled and the newer one is

activated.

• If the waiting station is busy and the queued CO Line is available, the available CO Line

will be directed to the next queued idle station.

• If the waiting station is idle, the queued CO Line will give a call back signal to the station

for 15 seconds. If the signal is not received at the station, the queue is canceled and the

next station in the queue will receive the signal.
