Hello;
i try to add a regular expression to from_pattern column in trusted table.

Fromuser header is   sip:8503027337@ip

i added from pattern ^sip:850[0-9]{7}  - didnt matched!
try to like that    
^sip:850[0-9][0-9][0-9][0-9][0-9][0-9][0-9]  - matched.

it is kinda weird. why first pattern was matched.

Kamailio 4.1.7 (x86_64/linux) 85ffd9

Thanks
