I see a phone answering machine on Ebay, maybe 10 or 15 years old, and
it has "CPC Disconnect". I googled and learned that was Calling Party
Control Disconnect.

All of the google hits I can find involve fancy local phone systems
with devices that cost 70 dollars or more, and they just say their
device provides it. They assume people already know they want it.

I can't figure out what CPC Disconnect is. Especially as it pertains
to a simple residential line.
