Prime Line Selection
n Description
Prime Line Selection allows an extension user to place or answer a call over a specific trunk by just
lifting the handset. The user does not have to first press keys or dial codes. This simplifies handling
calls on a frequently used trunk.
A prime line is effectively a single exchange line placed into its own trunk group for outgoing access
and it own ring group for incoming ringing.
Prime Line Selection has the following two modes of operation:
·
Outgoing Prime Line Preference
Lifting the handset seizes the Prime Line. Outgoing Prime Line Preference would help a
telemarketer who always needs a free line to call prospective clients. The telemarketer just lifts the
handset and the Prime Line is always available. (Outgoing Prime Line Preference may be affected
by Incoming Prime Line Preference).
·
Incoming Prime Line Preference
When the Prime Line rings the extension, lifting the handset answers the call. Incoming Prime
Line Preference could benefit the Service Department dispatcher who must quickly answer
customer's service calls and then dispatch repair technicians. The dispatcher would have the
assurance than whenever a customer calls in, the dispatcher just lifts the handset get their call.
(Incoming Prime Line Preference can optionally seize an idle line appearance).
