[Kamailio-Users] PCRE / Regex Module

[Brandon Armstead]

Hello,
    I do not know why it did not dawn upon me to simply use the =~ operator.
 However it does appear to error out / not compile:

"(?i)(restricted|anonymous|private|unknown|unavailable)", i.e.

produces a runtime error:

if($hdr(From) =~ "(?i)(restricted|anonymous|private|unknown|unavailable)"){

}

* sending this to list.
