Types of Lines

The following are the types of lines:
• Private line: A line that is only accessible to one
telephone.
• Shared line: A line that is accessible to multiple
telephones.
The LED associated with the line key indicates the sta-
tus of a call on the line regardless of whether the call is
conducted on this particular multiline phone or on an-
other multiline phone on which the shared line is also
displayed.

Line Types

The available lines can be used as described below. Re-
gardless of the line usage, all of these lines can be ei-
ther private or shared.
• Prime line: Every multiline telephone has one
prime line. This line generally uses your public num-
ber, which means that you receive your incoming
calls on this line. A prime line can be private or
shared.
Some features are only applicable to the prime line
to ensure that conflicting feature settings between
different multiline telephones on the same shared
line cannot occur.
• Secondary line: Every multiline telephone can have
additional lines, which are prime lines of other mul-
tiline telephones.
• Phantom line: The difference between a phantom
line and other line types is that it is not the prime line
on any telephone.
Phantom lines are particularly useful for deflecting
calls. The administrator can configure your prime
line so that it switches to a phantom line if a second
call is incoming. If you are speaking with a second
party, this configuration allows you to hold, transfer
or deflect the call.
