ncidd.blacklist - Man Page

The ncidd.blacklist file contains the expressions to match against a telephone call name or number.

If the hangup option is set and if there is no match in the whitelist file, a match in the blacklist file will cause ncidd to automatically terminate the call.

The ncidd.blacklist file understands 4 types of lines:

blank line:

skip it

comment line:

skip it

entry line:

process it

Entry lines contain one or more expressions and an optional comment. An expression is either a string of non-blank characters or everything between double quotes.  Multiple expressions are separated by spaces. A comment must be last.

Entry line comments are either normal comments or match name comments.

A normal comment begins with a '#' and must not be immediately followed by an equals sign. Anything after the '#' is ignored.

A match name comment begins with '#=' and is followed by a name to display for the caller when the entry matches either the number or name of a call. Do not use double quotes around the name.

Example:    407-555-5670    #= Unwanted Marketing Call

• Each expression is compared to the caller name and number.
• Upper and lower case letters are significant.
• The number must be a string of digits as they appear in /var/log/cidcall.log.
• A leading '1' is required if it is in /var/log/cidcall.log.
• A partial name or number can match.
• If regular expressions are used (regex = 1):

• A '^' at the beginning of an expression means it must match at the start of a name or number.
• A "^1?" at the beginning makes a leading 1 optional. This is only useful for US/Canadian numbers.
• If an expression is longer than the name or number field it will never match.

Blacklist the unassigned 999 area code with and without a leading 1
^1?999

Blacklist callers with the name "BAD MARKETING":
"BAD MARKETING"

Blacklist anything with "MARKETING" in the name:
MARKETING

Blacklist a caller name and a different caller number on one line:
