Multiple line appearances and line keys
A phone number assigned to a line key on an
IP phone is called a line appearance. The line
keys on your phone can have repeated
numbers, different numbers that belong to
you, or numbers that belong to others. When
a call comes to a number, all phones with that
number as a line appearance ring at the same
time. When the call is answered, how it's
handled depends on the line's call presence.
Shared call presence—When a call is
answered and put on hold, any other phone
with that line appearance can take the call off
hold.
Not shared call presence—When a call is
answered, it becomes exclusive to the phone
that answered it and no longer appears on the
other phones.
