Hello, I have the following pcre regex method call: pcre_match("$hdr(From)", "(?i)^(restricted|anonymous|private|unknown|unavailable)") to match calls that are sent without a proper ANI in a case-insensitive manner, however it does not seem to return true for the following example From Header:
From Header: "Unavailable"
<sip:Restricted@192.168.47.68sip%3ARestricted@192.168.47.68
;tag=gK07327e23
Any thoughts / input is appreciated, and as always thank you for your help!
Sincerely, Brandon Armstead
Hello, Just realized the " and the ^ is probably why it is not matching -- total oversight. Thanks guys!

You are using ^ symbol which means that the string MUST START by: restricted|anonymous|private|unknown|unavailable
But your string $hdr("From") starts by "Unavailable" (*including* the quotation marks so it doesn't match).
If the From URI username is enough (Restricted) you could do:
pcre_match("$dU", "(?i)^(restricted|anonymous|private|unknown| unavailable)")
If you need to match the Display-Name ("Unavailable") then you must add the quotation marks to the regular expression:
pcre_match("$fn", "(?i)^(")?(restricted|anonymous|private|unknown| unavailable)(")?")
Note that I use $fn rather than $hdr("From"), being $fn the From Display-Name: http://kamailio.org/dokuwiki/doku.php/pseudovariables:1.5.x#from_display_nam...

Also, it's better if you use =~ instead of pcre_match since =~ compiles the regular expression during script file initial parsing. 'regex' module is useful if you use the pcre_match_group() function (which matches against the content of a file separated by sections).
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.

Because =~ operator doesn't implement like (?i) sysntax. Use just:
"(restricted|anonymous|private|unknown|unavailable)"
Note that =~ uses case insensitive.
Inaki,
Ahah! thank you for this bit of information. Sent from my Verizon Wireless BlackBerry
