[Serusers] checking permissions with if (!$f.gw_acl=="1")

Hi all, I'm using SER2.0 (testing) and I have a question regarding checking the acl AVP to verify that the user is allowed to call PSTN destinations with if (!$f.gw_acl=="1") { ... In the "user_attrs" table I have this entry: uid name value type flags alice(a)xyz.hr gw_acl 1 2 61 before checking this "gw_acl" I do load attributes with load_attrs("$fu", "$fu.uid"); but I keep entering above "if" statement. So I would appreciate any help about how to solve this issue, in which tables I need to enter which values... I have solved this checking with avpops module and "avp_check" function, but as I already use new AVP schema in SER2.0 for loading other user attributes I would like to use it with this "gw_acl" also.
