Prime Line Preference

Description

Prime Line Preference allows an extension user to place or answer a call by just lifting the handset. The user does not have to press a line key, loop key, or the INTERCOM key first. This simplifies handling calls. In programming, you designate a line key, loop key, the INTERCOM key, a line, or a Line Group as the extension’s Prime Line. With a line key, loop key, line, or Line Group, the associated line (or lines) becomes your Prime Line. With the INTERCOM key, you get Intercom dial tone when you lift the handset. Any number of extensions can have the same Prime Line assignment.

Prime Line Types

There are two types of Prime Line Preference: Idle Prime Line and Intercom Prime Line.

Idle Prime Line

Idle Prime Line lets a user place or answer a Prime Line call by just lifting the handset. An extension’s Idle Prime Line can be any line or Line Group, regardless of whether the extension has a line or loop key for the line or group.
Idle Prime Line to any line or Line Group is also available at single line telephones.

Intercom Prime Line

With Intercom Prime Line, an idle extension user hears Intercom dial tone whenever they lift the handset or press SPEAKER. Intercom Prime Line may help the extension user that most often uses Intercom functions or calls co-workers. If an extension’s Busy Lamp Field is disabled (which is the default), the Feature Keys do not go into the DSS mode when the user lifts the handset.

Secondary Prime Line

If your Prime Line is busy, Secondary Prime Line allows you to automatically connect to an alternate Prime Line when you lift the handset. For example, you can have line 1 as your Prime Line and Line Group 90 (dial 9) as your Secondary Prime Line. Normally, you’ll get line 1 when you lift the handset. If line 1 is busy, however, you’ll automatically connect to an available line in group 90 instead.

Prime Line and Ringing Line Preference

Ringing Line Preference has priority over Prime Line. For example, an extension with Ringing Line Preference will answer a ringing line, not get dial tone on their Prime Line. In addition, a Ringing Prime Line will have priority over any other ringing line. The seize priority is as follows:

Ringing Prime Line
Ringing non-Prime Line
Prime Line

Prime Line and Privacy Release Groups

Tailored for residential applications, Prime Line and Privacy Release Groups allow you to automatically join a call in progress when you lift the handset. You can do this if:

The outside line is busy.
The busy line is on your Prime Line key.
The extension on the call is in your Privacy Release Group.

Primeline Key Remains On Display
