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 exten-
sion’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.
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.
Prime Line vs. Ringing Line Preference
Ringing Line Preference has priority over Prime Line. For example, an extension with Ringing Line Prefer-
ence 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
Conditions
• None
Default Setting
• Intercom Prime Line enabled.
Get dial tone for a new outside or Intercom call just by lifting the handset.
