6. Your problem:
I need to know how this authentication works.
i noticed that security is off by default, but there is four differnet things for security. one setting will let me auth. with any username as long as the password was in RadiusCat. then other settings will prevent me from using IVRCat (no call can be answered my IVRCat). and then it is jsut wide open.

would anyone know what the correct settings are to set security correctly?
thanks!
