Any entrepreneurs out there? The feature that I would most like for my
phone (after the caller ID and voicemail features that I have come to
rely on) is the ability to block calls from specific numbers and
ranges of numbers. Although I can buy a service that allows me to
block calls from a single (or possibly several) specific numbers, this
is costly and the term is limited. What I most want to do is block all
calls from 1-8xx numbers, as well as block calls from any telemarketer/
telephone survey firm that gets past that protection.
The telcos don't seem interested in selling such a service: it would
undermine their revenues from these heavy users of their services. I
think that the technology for this should be quite doable, however.
Wouldn't it be possible to design a phone that did this kind of
blocking? I would buy one, and I bet a lot of other people would too.
You can get anti-spam software for your computer. You can ask the post
office to not deliver junk mail to your address. Why can't you stop
junk calls with your telephone/telephone service?

One of the joys of running Asterisk (and I assume any of the other
open-source software PBX) is that the developers aren't under the
thumbs of the telcos. Features like this exist in the base system.
There are even hacks to send SIT tones down the line when
telemarketers call, (although the utility of that has been debated.)
Setting up the PBX was a bit of work, but it sure is nice not the have
the barrage of phone spammers calling any more. I find the biggest
barrier to phone spammers is the IVR system ("Please press 1 for XXX.
Press 2 for YYY.") The spamming autodialers are too stupid to press a
number, so the call never dials through. In a way this is a turing
test and the autodialers fail.

Thanks Wolfgang, I work mostly on Linux system, so I suspect that an
open source PBX might be my best option, although finding time to set
it up might be another matter.
Thanks also to Steven, but I run Win systems as rarely as possible:
they seem to have a built-in pipeline from my wallet to Bill Gates'
bank account, and I'm trying to choke that off as much as I can.
Hardware is expensive enough, and I think that Richard Stallman is
just a bit too moderate for my tastes! ;-)

I do not think that is possible.
AFAIK, 800 numbers (inward WATS) is completely different than outward
WATS. I don't think anyone has a phone number listed with an 800 area
code.
It seems what you seek is a block on lines equipped with outward WATS
and that is not possible or realistic. Plenty of legitimate business
calls originate from such lines, and residences now have that as well.

How does the U.S. post office know what is "junk" mail? While junk
mail is typically Third Class (whatever they call it nowadays), it may
be First Class as well. Also, some legitimate mail may be sent Third
Class to save money, as some non profit organizations do. Anyway, I
was not aware the Post Office will filter out mail for you.

Junk calling is determined by U.S. state and federal law. There are
"do not call" lists you may sign up for. However, the law allows
certain types of calls--non profits, political, prior business
relationship--to go through.
