Enhanced Prime Line with 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. This will happen if the outside line is busy, the busy line is on your Prime Line key, and the extension on the call is in your Privacy Release Group.

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.

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.
