Caller ID Active
When you enable this feature, the system can detect an off-hook
condition in a telephony device such as a modem, FAX machine,
industry-standard telephone, or similar device that an installer has
connected to a line ahead of the system. When the system detects the
off-hook condition, it makes a busy indication appear at system
stations that have this line appearance.
NOTE: Busy Lead Detection only works on line two of each line
board.
When you enable this feature, the system detects a break in loop
current anytime one occurs during an outside call. You must set this
feature to yes for DISA lines
When caller identification (ID) information is available from the
central office, take this programming action to match the line port to
the feature. You must also assign the caller ID lines to the stations and
assign special-purpose station buttons to control the feature. Refer to
section 15.2 for complete caller ID programming details.
