Worked as expected:

Can you try in kamailio.cfg:
$var(x) = "912345678";
if($var(x) =~ "9[0-9]{4}") {
xlog("regexp matched\n");
}
Same regexp library is used. If this one works, then loading the value
from trusted might have some issues.
Cheers,
Daniel

I tried and didn't work.

I tried before attempting to discover what was wrong with the
expression and no useful messages regarding this.

it should be postfix regexp, at a matter of fact, the input is passed to
the regexp implementation in libc, it is not written from scratch by
kamailio. I have seen in the past some situations that a regexp didn't
work as expect on various versions of operating systems.
Can you try and see if 9([0-9]){4} works?
Otherwise, try with debug=3 in kamailio.cfg and see if you can spot some
useful debug messages.

Daniel
