They might also want to read higher up in this thread, where advice was given as to how to configure round this behaviour. Land unauthenticated SIP calls in a context with limited or no access. Asterisk allows you to do exactly what you want. Many people use this behavour to accept unsolicited SIP calls and direct them to an IVR or a specified extension, for example. But you probably wouldn't allow them to make toll calls.
