CCXML application definition pattern matching syntax
The following table describes the syntax used to specify patterns for matching the
dialed number (DNIS) for inbound calls. This is based on standard regular expression
syntax.
Symbol
Description
.
Wildcard that matches any single digit or character. For example, 123.... matches any
(period)
dialed string beginning with 123, plus exactly four additional digits.
[ ]
Range of digits. A consecutive range is indicated with a hyphen (-); for example, [5-7]. A
non-consecutive range is indicated with a comma (,); for example, [5,8]. Hyphens and
commas can be used in combination; for example, [5-7,9].
Note:
Only single-digit ranges are supported. For example, [98-102] is invalid.
( )
A pattern; for example, 408(555). Used in conjunction with the symbol ?, *, or +.
?
Preceding digit occurred zero or one time.
* or %
Preceding digit occurred zero or more times.
+
Preceding digit occurred one or more times.
The following table provides examples of destination patterns and how they are
interpreted:
