OK, I see landline solutions but what about cell phone solutions
I am on Sprint. Samsung Galaxy S5 lollypop.
Is there a forum that will cover that if someone here has no good
I have been using what my phone lists as "Call Control v220.127.116.11" for a
couple of years now and my cell phone telemarketing/robo calls have
dropped by at least 90%.
Just checked Google Play, and it looks like they have changed the name
to "Call Blocker - Blacklist App" viz
I have heard good things about a service called NoMoRobo, but it
requires that you phone service support something called "Simultaneous
Ring". We have the most el-cheapo basic phone service and I am too
cheap to pay more, so I do not have experience.
Another option (which I am toying with) is going over to a VOIP provider
for phone service.
I already have all outgoing, except 800, calls going out on VOIP.
If I were to switch the incoming over, I could use a service provided by
my VOIP provider (CallCentric.com) that prefixes every incoming call
(except those on a GoldList that I maintain) with an announcement like
"Please press 3 to talk with somebody...".
I figure robocallers won't be able to deal with that challenge-response
situation... at least for a few years.

A few of the people who called me would press the button. Most wouldn't,
so I would still need to have the phone ring so I could get the caller
ID and answer (pressing the key for them).
I didn't have an exception list like you did. It would still be a
problem (new important callers who won't press the key).
Something is wrong here. I may get a few "dead air" type of phone
calls, but most of them have a recorded robotic voice that appears
when I say something or when I pickup the line. Telemarketers might
be evil, but they're not stupid. They would not waste the cost of a
call just to deliver "dead air". Certainly not for 4 years of "dead
air". Something is wrong.
My guess(tm) is something is wrong with your Verizon POTS line that is
initiating a ring, but not completing the call. I've seen this with
some electronic phones, where there is sufficient crosstalk in the
wire bundle to pickup some of the ringing voltage from other lines in
the bundle. However, those don't also pass Caller ID numbers and only
ring a few phones in the house, so that's not a likely failure mode.
Unless the provisioning is mangled or the Verizon switch has gone
insane, I can't guess(tm) what might be causing the calls.
I was thinking it might be a fax machine trying to send a fax
repeatedly, but that would be from one phone number and certainly not
for 4 years. You would also hear a tone as the originating fax
machine tries to negotiate the call. Are the numbers shown on the
Caller ID all identical or perhaps similar as from a calling group?
I assume that you've contacted Verizon. Changing your phone number
might be an obvious option that I'm sure they would have suggested. If
the problem persists, it's a hardware or switch problem. If it goes
away, problem solved.
On the other hand, the vague problem description, improbable symptoms,
and odd selection of crossposted newsgroups leads me to suspect that
this is some manner bad joke or time burner. Please assure me this
problem is real by posting some details.

Using a "SIT tone" might help:
"In telephony, a special information tone (SIT) is an in-band international standard signal consisting of three rising tones indicating a call has failed. It usually precedes a recorded announcement describing the problem
"Because many predictive dialers (used in telemarketing) respond to SITs, consumer devices such as the TeleZapper play an Intercept SIT to trick the telemarketer's equipment into flagging a called number as disconnected.
Alternatively, the above recordings of SITs could be used on a voicemail or answering machine, or played manually on a computer, to achieve a similar effect."
Assuming USA, assuming landline.
Add sit.wav to the beginning of your answer message.
It cut robo calls by about 30%. Some robo calls go right
to a recorded message and never hear the sit.wav though.
Or just use sit.wav as an answer message and nothing else.
Doing that not only confuses robo machines but confuses
humans, too, and they hang up.
People who *know* you and your practices adapt easily.
Where you get screwed is the folks who contact you only occasionally.
Or, who may "vary" with each contact (e.g., someone calling from
your doctor's office, the public library, a friend who's forgotten
this idiosyncrasy, etc.)
That;s why its better to engage them interactively. Someone
from your doctor's office is more likely to "comply" with some
minor inconvenience in contacting you ("Please press 3")
than they would "remember" the service disconnected message.
If you answer on a low ring count, there's no real way they can
differentiate between a genuine message and a spoof. And,
what do they do if they *suspect* it isn't genuine? Remain on the
line and see if the message repeats? Or, if the connection is
Ideally, you are "listening" during the outgoing message (announcement)
so legitimate callers can short-circuit the message and get to
the *real* answering machine (or, cause a ring-thru).
While most of these firms are annoying, it really wouldn't be *smart* for
them to persist. If you've gone to these lengths, it's because you are
UNLIKELY to ever accept any of their "offers".
