Hi, I'm trying to add authentication to ser (see below). I'm able to load ser without errors, but when I want to add a user using serctl add 1012 test magnum.test.net , I get error: 400; check if you use aliases in SER Any ideas? Regards, YY ser.cfg --------- if(uri != myself){ route(1); break; }; if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!proxy_authorize("magnum.test.net", "subscriber")) { proxy_challenge("magnum.test.net", "0"); break; }; save("location"); break; }
