That's why I mentioned challenge/response; that's a bit harder to
crack. (And there are other things you could do, such as allowing a
passphrase bypass.)
There's also call holding; "$snippet has called, and would like to
speak to you. Would you like to accept this call?"
That kind of service has been in use for decades. Automate it, and you
can configure schedules, degrees of access, etc. And accumulate denied
calls for spam/ham classification.
