A regular expression is a special text string for describing a search pattern or for input validation.  In LUCS you can access and define "Regexes" to find and replace specific strings. The purpose for this is to find specific patterns in SIP URIs, Caller or Agent telephone numbers and parse the information into a format that is more suitable for a CRM or Ticketing system.
