Hi, Kamailio uses the following syntax for =~ operator:

if ( $rU =~ "^2[0-9]{2}$" ) {

Reading the SR commits, it seems that SR will support regular expressions in 'switch' stament:

switch ($rU) { case 200: # INTEGER [...] case "alice": # STRING [...] case /2[0-9]{2}/: # REGULAR EXPRESSION [...] }

If the above is correct, it requires two different syntax for a regular expression: a) =~ "^2[0-9]{2}$" b) case /2[0-9]{2}/:

Wouldn't make sense to have an unique syntax for regular expressions? IMHO the best one is: /2[0-9]{2}/

so =~ would use: if ( $rU =~ /^2[0-9]{2}$/ ) {

Opinions? Regards.
