Replacing a telephone

In a powered-up system, an existing telephone can be replaced
by a new telephone. A new telephone is one that was not
previously in service within the system.
Replacing telephones of the same type
If an existing telephone is unplugged, and a new telephone of
the same type is then plugged into the same jack, for example,
replacing a T7208 set with another T7208 set, the new
telephone acquires the programmin gand the internal number
of the old telephone. This is normally done to replace a
defective telephone.
Replacing telephones of different types
If an existing telephone is unplugged, and a new telephone of
a different type is plugged into the same jack, the new
telephone keeps the old internal number. The new telephone
receives a default profile for a telephone of its type. You then
need to program the terminal as described in the Modular ICS
6.0 System Coordinator Guide.
If the telephone being replaced has more lines than the new
telephone, automatic outgoing line selection may not work
with the Handsfree feature. A line must be selected manually.
