Mirko, sorry for confusing you.
You are right about pattern and my example phone number. I've just replaced
everything with 0 after 093. I have no problems with pcre :) Btw we can
even test it with fs_cli, don't we? :)
freeswitch at vzakhozhai> regex 0930000000|^0[1-9][0-9]{8}
true
freeswitch at vzakhozhai> regex 0930000000|^0[1-9]{9}
false
