[Serusers] setflag

Is there any way using serctl or querying the ser database on mysql to determine what flags were or were not for a Registered UA I am using nat_uac_test("2") to only select UAs that have not already been set up for DMZ or Port forwarding. I want to verify that only the UAs without Port Forwarding or DMZ are having Flag(6) set. if (nat_uac_test("2")) { if (method == "REGISTER" || ! search("^Record-Route:")) { fix_nated_contact(); # Rewrite contact with source IP of signalling if (method == "INVITE") { fix_nated_sdp("1"); # Add direction=active to SDP }; force_rport(); # Add rport parameter to topmost Via setflag(6); # Mark as NATed }; };
