Hi, I have the following ser.cfg code: lookup_user("$tu.uid", "@ruri"); load_attrs("$tu", "$tu.uid"); if ($tu.forward_as_blind) { the if statement gives the negative result what is I think wrong because the attribute is present and it's value is 1. here is the output from dump_attrs(): Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:540: class=GLOBAL Jul 6 08:35:13 sen ser[1445]: AVP["lang"]="en" Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:550: track=FROM class=DOMAIN Jul 6 08:35:13 sen ser[1445]: AVP["did"]="voip.rd.touk.pl" Jul 6 08:35:13 sen ser[1445]: AVP["digest_realm"]="voip.rd.touk.pl" Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:560: track=TO class=DOMAIN Jul 6 08:35:13 sen ser[1445]: AVP["did"]="voip.rd.touk.pl" Jul 6 08:35:13 sen ser[1445]: AVP["digest_realm"]="voip.rd.touk.pl" Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:570: track=FROM class=USER Jul 6 08:35:13 sen ser[1445]: INFO: No AVP present Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:580: track=TO class=USER Jul 6 08:35:13 sen ser[1445]: AVP["datetime_created"]="2007-04-18 07:51:34" Jul 6 08:35:13 sen ser[1445]: AVP["email"]="tzl(a)touk.pl" Jul 6 08:35:13 sen ser[1445]: AVP["forward_as"]="192.168.0.165:6060" Jul 6 08:35:13 sen ser[1445]: AVP["forward_as_blind"]=1 Jul 6 08:35:13 sen ser[1445]: AVP["forward_as_default"]=0 Jul 6 08:35:13 sen ser[1445]: AVP["forward_as_invite"]=0 Jul 6 08:35:13 sen ser[1445]: AVP["forward_as_message"]=0 Jul 6 08:35:13 sen ser[1445]: AVP["forward_voicemail"]=0 Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:590: track=FROM class=URI Jul 6 08:35:13 sen ser[1445]: INFO: No AVP present Jul 6 08:35:13 sen ser[1445]: INFO: avp.c:600: track=TO class=URI Jul 6 08:35:13 sen ser[1445]: INFO: No AVP present please point me what did I miss?
