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
Because the M7100 telephone does not have line buttons, it
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 you to select a line button
to take a call off hold, you press
˙ on the M7100 telephone.
On M7100 telephones, you can answer a second call by pressing
˙ . Your active call is put on hold and you are connected to
the waiting call. You can have no more than two calls at a time.
The M7100 telephone cannot have a © button. When
applicable, special instructions for the M7100 telephone are
included with each feature description.
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 will be 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.
