Line Pools; Overflow Call Routing; Telephones With No Line Buttons - Nortel Compact ICS 7.1 Coordinator Manual

Line pools

A line pool allows each telephone access to external lines from a group (or
pool) of external lines. You can access such lines by pressing an intercom
button and entering a line pool access code, a destination code that uses that
line pool, or by pressing a memory button programmed with the line pool
feature code and a line pool access code.

Overflow call routing

If a call comes in for a target line that is busy, Norstar routes the call to the
prime telephone for that target line. If there is no prime telephone assigned
to the target line or if a call cannot be directed to a target line, the call goes
to the prime telephone for the external line used.
Overflow routing for incoming calls is used with the Routing Service
programmed by your installer. A Service must be active for overflow
routing to be in effect. Overflow routing is not available in normal service.
Tips -
is busy, you hear the expensive route warning tone. Your
telephones displays an expensive route warning. To avoid
using the normal, expensive route, release your call.
Overflow routing directs calls using different line pools.
Therefore, a call may be affected by different line filters
when it is handled by overflow routing.

Telephones with no line buttons

The 7000 and 7100 digital phones and the Digital Mobility phone do not
have line buttons, therefore, they work differently from other Norstar
telephones.
• Where other telephones can require that you select a line button to
answer a call, on the these telephones you simply pick up the receiver.
• Where other telephones require you to select a line button to take a call
off hold, you press the Hold button.
