Regular Expressions

Last Updated : Feb 26, 2015 |

You can configure routing in Session Manager by creating regular expressions and associating them with a routing policy.

Regular expression syntax is based on Java syntax. Some of the syntax related rules are:

  • The asterisk character "*" matches any character string.

  • The dot character "." matches one character.

  • The backslash character "\ " makes a character lose its special meaning, if any

Some examples are:

  • For “www.sipentity.domain.com”, use the string “www\.sipentity\.domain\.com”

  • For “192.14.11.22”, use string “192\.14\.11\.22”.

  • The routing policy with a regular expression .*@.*\.de routes all calls requesting a domain in Germany (for example, name@company.de) to a Frankfurt Gateway.
