The other solution is line blocking, in which all calls have the id
    blocked. Downside: what if you had to call 911 and the number was
    blocked because you forgot to dial the extra numbers to send your
    number. And telemarkters would pay a one time fee to block the
    number so you would be in the same boat you are now. Pick up phone,
    listen to pitch, hang-up rudely...

This is incorrect, 911 calls have realtime ANI like 800 #'s and CAN'T
be blocked.  As far as telemarketers go, ask them to remove you from
their list, if they continue to call (or if its a robo-call) then
(don't know about availability in other states) start hitting *57 (call
trace) which logs the number with the phone company as a harassing
call.  After three such logs the phone company is usually obliged to
take action (usually by threatening to cancel their phone service).

    So, how do you handle not giving out your unlisted number when you
    call an 800 number, even when you pay to have your number
    blocked??

Four choices; don't call 800 #'s, sacrific privacy (they will get
everything they want from your credit card anyway if your ordering
anything), use one of the ANI stripping call forwarding services, use a
different phone (pay phone).

What bothers me is the fact that even non-published numbers are.  I
recently called a local pizza place which I have NEVER patronized
before, they asked for my name (reasonable since I was having a pizza
delivered) and in less than a second they had my address and
unpublished phone number.  CallerID doesn't start here for another week
or so and I'm line-blocked.  I was too shocked to ask them how they got
this information.
