Route Pattern Wildcards

Special characters in CUCM patterns such as X, !, [ ], ., @, # and + that match ranges and lengths of digits.

Definition

X matches any single digit 0 to 9; ! matches one or more digits; [ ] matches a single digit from a range or list, with ^ for exclusion; ? matches zero or more of the preceding digit or range; + matches one or more of the preceding; . separates an access code for digit discard; @ matches the North American Numbering Plan; # can terminate interdigit timing; and \+ matches a literal plus sign for E.164 dialing.

Example

\+1[2-9]XX[2-9]XXXXXX matches a +E.164 North American number.

Exam tip

Variable-length ! patterns trigger interdigit timeout (T302) unless the caller presses # or urgent priority applies.
