/* For UK phone functions, do the following server side processing:
 * Compare original input with this RegEx pattern:
 * ^\(?(?:(?:00\)?[\s\-]?\(?|\+)(44)\)?[\s\-]?\(?(?:0\)?[\s\-]?\(?)?|0)([1-9]\d{1,4}\)?[\s\d\-]+)$
 * Extract $1 and set $prefix to '+44<space>' if $1 is '44', otherwise set $prefix to '0'
 * Extract $2 and remove hyphens, spaces and parentheses. Phone number is combined $prefix and $2.
 * A number of very detailed GB telephone number RegEx patterns can also be found at:
 * http://www.aa-asterisk.org.uk/index.php/Regular_Expressions_for_Validating_and_Formatting_GB_Telephone_Numbers
