Priority Calling 

Refer to 

‘‘Station’’ on page 882

 for information about and field descriptions on 

the Station screen.

Priority Calling provides a special type of call alerting between internal telephone 
users, including the attendant. The called party receives a distinctive ring when the 
calling party uses Priority Calling.

You administer the priority-calling ringing-pattern system wide. Default is a 
3-burst alerting signal. You allow feature use for each telephone user by 
administering the user’s class of service.

The following types of calls are always priority-calling calls:

■

Call coverage consult 

■

Automatic callback

■

Ringback queuing

■

Attendant intrusion

■

Security violation notification

The system generates the call waiting ringback tone that a single-line telephone 
user hears even if the user is active on a call. In contrast, the system does not 
generate the pattern for a multiappearance telephone if there are no idle call 
appearances. In this case the caller hears busy tone. However, the system does 
generate the pattern if the telephone has an idle call appearance, including the one 
reserved for call origination.

■

Abbreviated Dialing

If a user wants to make a priority call to a number in an abbreviated dial 
list, the Priority Calling access code and the AD code must be programmed 
on one button. If a user attempts to use Abbreviated Dialing (either by 
button or FAC) after dialing the Priority Access Code, the system denies 
the call.

■

Call Coverage

Priority Calling calls do not redirect to coverage unless the caller activates 
Go to Cover. If the call redirects, it remains a priority call, and the covering 
user receives a distinctive (default is three-burst) ringing signal.
