HI, I rewrote the pstn transfer script: if (uri=~"0*@DOMAINNAME") { if (!www_authorize("DOMAINNAME", "subscriber")) { www_challenge("DOMAINNAME", "0"); break; }; rewritehostport("IP:5090"); t_relay_to_udp("IP", "5090"); break; }; now only call that are really coming from an user I have authorized are trasfered to telco gw, right ? But now ... how can I select this privilege just for some users ? I already have assigned a "local" permission to some of them .... Tnx ! Alessio Focardi
