[VoIP] Fun with Pat and Jane

My ITSP (teliax.com) sends calls as "private" and "unknown"
depending on whether or not the lack of CID was volitional
or not.  I only block "private".

I prefer not to trap "unknown" since I get international
calls which often don't have CID.

Reading what other are saying in this thread, it sounds
like I should probably trap domestic calls that don't
come with a valid NXX-NXX-XXXX number (that way I'd block
nonsense like 800-123-4567)
