– Plus sign (+)—Matches a sequence of one
or more matches of the character/pattern.
Note The plus sign used as part of the digit string
is different from the plus sign that can be
used in front of the digit string to indicate
that the string is an E.164 standard number.
– Circumflex (^)—Indicates a match to the
beginning of the string.
– Dollar sign ($)—Matches the null string at
the end of the input string.
– Backslash symbol (\)—Is followed by a
single character matching that character or
used with a single character having no
other significance (matching that
character).
– Question mark (?)— Indicates that the
previous digit occurred zero or one time.
– Brackets ([])—Indicates a range of digits.
A range is a sequence of characters
enclosed in the brackets, and only numeric
characters from “0” to “9” are allowed in
the range. This is similar to a regular
expression rule.
– Parentheses ( )—Indicates a pattern and is
the same as the regular expression
rule—for example, 408(555). Parentheses
are used in conjunction with symbols ?, %,
or +.
For more information on applying
wildcard symbols to destination patterns
and the dial strings that result, see the
“Configuring Dial Plans, Dial Peers, and
Digit Manipulation” chapter in this
configuration guide.
• T—(Optional) Control character indicating
that the destination-pattern value is a variable
length dial string.
