you can get a list of all NPA-NXXs that are used by cell carrier
and use that as a starting point. Then add to that the list of
LRNs used by call carriers which may or may not be included in the
first list.<br>
<br>
Then you need to dip your traffic and compare the DNIS/LRN to the
combined list. If the number is ported the LRN will match the
list. If the number is not ported and is cellular it will be in
the list of NPA-NXX. If not cellular it won't match the list.<br>
<br>
Either way if there is a match to the list then you can reject the
call for that customer. (I believe you are a Sansay customer so
you can set up a route table with the combined list and then use
it as the primary route table for those customers and then link to
normal tables. I can have our support team put together the list
of current NPA-NXX but you'll need a LERG6 subscription to keep it
current).<br>
<br>
Good luck,<br>

<div>Is actually right. Legislation that blocks a company from
auto dialing a number based on it being a cell phone or
landline is extremely difficult to prosecute. Straight talk
has a home service that essentially uses a wireless carrier
backbone. I can pickup the base plug it in at my neighbors
house or better yet put it in my car on a power inverter and
wah lah my home phone is what it truly is a cell phone with a
110-220v power supply. Number Portability would make wireline
and wireless number location nearly impossible. Manual dialing
would be the only way to prevent an auto dialer issue. </div>

<div>Depending on your switch you should be able
to build a profile for the customer and reject

Personally, I wouldn’t take on the liability of
guaranteeing their auto-dialer only calls
landlines. You would end up being sued if you
make a mistake. IMHO, let them manually dial or
find a list scrubbing company that actually
works.<br>

<div dir="ltr">I have a customer in
market research who is legally
required to manually dial calls to
cell phones. Right now they are
considering abandoning all of
their auto/predictive dialer
software and going to manual dial
for everything, because the
list-scrubbing services have been
shown to be inaccurate. There are
extreme penalties for auto-dialing
a cell phone, and "best effort" is
NOT a defense to this, at all.
For example, Gallup just settle a
claim for $12M.
<div><br>
</div>
<div>So they need a totally
accurate way to prevent a cell
phone call from originating from
their dialer. The only thing I
can think of is some sort of LRN
dip + LRN-to-carrier-type
response. One of their people
talked to Neustar, but didn't
get great answers because he
doesn't really understand
telephony. Before I get in
touch with Neustar, I thought
I'd see if people here have some
ideas.</div>
<div><br>
</div>
<div>If you provide a commercial
product for this, please feel
free to tell me so on or off
list, the customer is willing to
pay for the service and we're
open to all options. I don't
have a budget number yet but
manual dialing is going to cost
them quite a bit for some types
of studies.</div>
