FK101, how to enable distinctive ring on the 7020.DESCRIPTION: SOLUTION ID:
117994
SOLUTION:
CAUSE: The 7020 does not have a built in distinctive ring feature.
SOLUTION: If this feature is required, an external fax/tel device that support distinctive ring must
be purchased.
Note: Distinctive-ring adds a second phone number to an existing line, then varies the ring pattern
(two short rings instead of one long one, for instance) to indicate calls to the different number.
Distinctive-ring switches can set to detect the ring patterns and route calls accordingly. These
switches can be obtained through local phone companies or computer/electronic supply stores.
Konica does not sell distinctive-ring switches.
