Usually, only the lines that are appropriate for a particular person appear at that
person’s telephone. When a line is assigned to a telephone it is automatically given
a line button on that telephone, if a button is available. The M7100 telephone has
no line buttons for its lines.
Calls on lines that ring but do not appear at a telephone are presented at an intercom
button.
You may be able to answer a call on a line that does not appear or ring at your
telephone. To pick up such a call, use Call Pickup, Call Park, or Trunk Answer.
A telephone may have buttons assigned for lines 001 to 003, but have only lines 001
and 002 programmed to ring as well. An incoming call on any of the three lines
causes a line button indicator to flash, and the telephone can be used to answer the
call. This is especially useful for people who monitor other telephone lines, but
want only their own lines to ring.
Target line
A target line is used to route a call directly to a particular telephone or group of
telephones. Target lines are used only for incoming calls. A single incoming line
may provide connections to several different target lines. This allows each person
or department in the office to have their own number without having a separate
external line for each number.
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, Enterprise Edge 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.
