Chapter 1 Telephone configuration overview 31

Telephone Features Programming Guide

In larger systems, lines are assigned to line pools and routes. To call out, you may have automatic

access to lines through the Intercom button on your telephone. You may also be given Access

Codes or Destination Codes that you need to dial as part of the dialout sequence to access a

specific line pool. Refer to “Using line pools” on page 47.

Prime line

(Unified Manager Programming)

You can program your telephone to select an internal line, an external line, or a line pool

automatically when you lift the handset. This is your prime line. The line choosen must be

assigned to the telephone under Line Access, as well.

Private line

(Unified Manager Programming)

A private line is limited to a selected telephone. You can pick up calls put on hold, or not answered

on a private line, only at the prime telephone for that telephone.

Target line

(Unified Manager Programming)

A target line routes a call directly to a selected telephone, or group of telephones. Target lines are

only for incoming calls. A single incoming line can provide connections to several different target

lines. Target lines allow each person or department in the office to have their own number without

having a separate external line for each number.

You can also assign a target line to a group of telephones, such as in the case of a Hunt group,

where you assign the target line to the Hunt DN.

Overflow call routing

(Unified Manager Programming)

If a call comes into a target line that is busy, the system routes the call to the prime telephone for

that target line. If there is no prime telephone assigned to the target line, or if you cannot direct a

call to a target line, the call goes to the prime telephone for the external line.

Overflow routing for incoming calls uses the routing service programmed by your installer.

Service must be active for overflow routing to operate. Overflow routing is not available in normal

service.

Note: If you select a voice over IP (VoIP) trunk or VoIP line pool as a prime line, the user

does not receive dial tone when the line is selected, therefore, it is not a recommended

setup for most applications.

Note: When you make a call and the programmed route is busy, you hear the expensive

route warning tone and see a display indicating the use of an expensive route. To avoid

using the normal, expensive route, release your call. Overflow routing directs calls use

different line pools, therefore, a call might be affected by different line filters.
