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 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.
M7100 telephone

sometimes works slightly differently from other Norstar
telephones. Where other telephones can require that you select
a line button to answer a call, on the M7100 telephone you
simply pick up the receiver. Where other telephones require
Tips -
When you make a call and the programmed route
is busy, you hear the expensive route warning tone and
see a display indicating that an expensive route is being
used. To avoid using the normal, expensive route, release
your call.
Because overflow routing directs calls using different line
pools, a call may be affected by different line filters when
it is handled by overflow routing.
