Features
Line Preference
n Description
Line Preference determines how a system phone user places and answers calls. There are two types of
Line Preference: Incoming Line Preference and Outgoing Line Preference.
Incoming Line Preference
Incoming Line Preference establishes how a system phone user answers calls. When a call rings the
system phone, lifting the handset answers either the ringing call (for Ringing Line Preference) or seizes
an idle line (for Idle Line Preference). The idle line can provide either Intercom or trunk dial tone (see
Outgoing Line Preference below). Ringing Line Preference helps users whose primary function is to
answer calls (such as a receptionist). Idle Line Preference is an aid to users whose primary function is
to place calls (such as a telemarketer).
Outgoing Line Preference
Outgoing Line Preference sets how a system phone user places calls. If a system phone has Outgoing
Intercom Line Preference, the user hears Intercom dial tone when they lift the handset. If a system
phone has Outgoing Trunk Line Preference, the user hears trunk dial tone when they lift the handset.
Outgoing Line Preference also determines what happens at extensions with Idle Line Preference. The
user hears either trunk ("dial 9") or Intercom dial tone.
Auto-Answer of Non-Ringing Lines
With Auto-Answer of Non-Ringing Lines, an extension user can automatically answer trunk calls that
ring other extensions (not their own). This would help a user that has to answer calls for co-workers
that are away from their desks. When the user lifts the handset, they automatically answer the ringing
calls based on Trunk Group Routing programming. The extension user's own ringing calls, however,
always have priority over calls ringing other co-worker's extensions.
Conditions
If a system phone extension has more than one call ringing its line keys, Ringing Line Preference
answers the calls on a first-in first-answered basis.
