Feature Guide

If the line is busy when a call is made, callback ringing will inform the caller when the line 
becomes free using this feature. After the extension answers the callback ringing, the dialled 
number is automatically redialled.

•

If the callback ringing is not answered within 10 seconds, the callback is cancelled.

•

If the extension hears a busy tone before dialling the telephone number, only the trunk or 
trunk group is reserved. After answering the callback ringing, the extension should dial the 
telephone number.

•

An extension can set only one Automatic Callback Busy. The last setting is effective.

•

Multiple extension users can set this feature to one trunk simultaneously.
However, a maximum of four extension users can set this feature to one extension.

•

The priority of the callback is the setting order.

•

This feature cannot be used for calls to a VPS or an ISDN extension.
