Fax Machines
NOTE:
Do not use this procedure for fax machines connected to analog multiline
telephones with a General Purpose Adapter (GPA). In a GPA configuration
features cannot be assigned to the fax independently of the telephone.
A maximum of 16 fax machines can have the Fax Message Waiting feature.
Additional fax machines (more than 16) can be installed, but these machines
cannot have this feature.
You can specify up to four telephones to receive the message-waiting indication
when a fax transmission is received. Note that fax machines can only send and
not receive message-waiting indications.
