Dial plan syntax
This page describes the syntax that you can use when adding dial plans.
Note: All IPv6 address fields in the ISDN Gateway require the IPv6 address to be enclosed in square
brackets [ ].
Syntax for conditions (Called number matches)
When you configure the Condition for a dial plan rule, you may want to specify a pattern for the called
number rather than specifying any of: match any called number, no called number or the exact called
number.
The table below describes the syntax you can use to express a pattern for the Called number matches
field in the condition of a rule:
Syntax
Description
Example
Numbers 0
to 9
To match a specific number, enter that
number.
Example: to match calls to "001234",
type 001234. The condition will match
that and only that number.
S To match an * (known as an asterisk or star),
enter an S.
Example: to match calls to "**1234",
type SS1234. The condition will match
that and only that number.
P
To match a # (known as a pound or hash),
enter a P.
Example: to match calls to "#1234", type
P1234. The condition will match that and
only that number.
D To match any digit, # (known as a pound or
hash), and/or * (known as an asterisk or star)
use the wildcard character D
Example: to match any number that
starts with "623" followed by exactly two
more digits, type 623DD. This condition
will match "62300", "62323", "62355",
"62399" "623*#", etc. but not "623" or
"623233".
?
To match once or zero times, use ?
Example: "6?" means match one 6 or no
6s, and is useful when used with the
wildcard "D" where you do not know how
long a number will be. The expression:
"67800D?" will match "67800" and
"678004" but not "67800666".
+
To match once or more, use + Example: "5+" means "match at least
one 5, but possibly more".
*
To match zero or more times, use *. This is
useful when used with the wildcard: "D*"
means "match any digit, any number of times".
Example: to match any number that
starts with "01", has any amount of digits
in the middle, and ends with "5", type 01
D* 5.
() Parentheses indicate substitution groups. To
include any of the incoming called digits in the
Example: to match any number starting
with "678", then followed by a number of
