Hi, could somebody tell me which characteres are allowd in a SIP URI? which RFC defines it? I ask it because I do a DB query with $ru so a SQL injection it's possible if RURI contains single or double ' So at the begining of the script I'd like to reject a message if the RURI contains illegal symbols. Could be useful a core function for this? Regards. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
