Emergency Telephone Dead - Nortel ICS Install Manual

594 / Problems with telephones
Status of a telephone that was replaced
The old telephone that was unplugged and replaced by a new
telephone loses its programming and internal number. The
internal number of the old telephone has been given to the new
telephone. The programming has either been removed or given
to the new telephone when it was plugged into the old jack.
The replaced telephone, if it is plugged back into the system,
is now treated by the system as a telephone not previously in
service.
Note -
different default settings on systems running MICS 6.0
and newer software. Therefore, if you replace one type
with the other, all user-programmed settings are lost
and the line numbering changes to reflect the default
numbering for the new telephone.
