Or, not to send it at all. One such miscreant called us yesterday, with
"Unknown Name / Unknown Number" on the CNID display. I connected and
hung up. It called back once more to see if I'd do it again; no surprises
there. I figure it, or its company, probably misconfigured their switch
to conceal their identity, and that's as bad as lying to me before we
connected.

A friend called through Skype and my CNID got "Unknown Name / 000-012-3456".
Another good one I remember was "Unknown Name / 999-999-9999".

I have to find a cheap PCI voice modem so I can have the computer take
care of these calls.
