[Asterisk-Users] Pattern Match - 0 or 1 digit

[Sum Ding Wong]

N matches any digit from 2-9. Are there any other wildcards outside of
the ones listed below

  <http://www.voip-info.org/wiki/view/Asterisk+Dialplan+Patterns>
   X          matches any digit from 0-9
   Z          matches any digit form 1-9
   N          matches any digit from 2-9
   [1237-9]   matches any digit or letter in the brackets
              (in this example, 1,2,3,7,8,9)
   .          wildcard, matches one or more characters
   !          wildcard, matches zero or more characters immediately
              (only Asterisk 1.2 and later, see note)
