Hello,

adding some more details to mention that regex operations done by the core (the =~ operator) use the libc posix regex functions, which do not support extended syntax. Also, these operations done by core use the case insensitive flag.

As mentioned by Henning, regex should be an alternative, or maybe dialplan if one wants db-storage+caching of those regex rules.

Moreover, if the above are not enough, a kemi embedded interpreter (e.g., app_lua, app_python) can be used with inline execution in kamailio.cfg routing blocks -- those external scripting languages should have many options for regex matching.

Cheers,
Daniel

Subject: [SR-Users] Caseless regex

 

Hello,

 

Is it possible write more readable regular expression

if ($tU =~ "(?i)^test$") {

    ...

}

instead of "^[tT][eE][sS][tT]$"?

 

On the first option, I get the error:

0(47250) ERROR: <core> [core/rvalue.c:3038]: fix_match_rve(): Bad regular expression

 

Regards,

Marat
