| is there any way to determine if a phone number belongs to an actual
landline or a VOIP service? my company requires customers to provide a
landline number to help prevent fraud, but we've recently been caught out by
people using VOIP services. help!

Not exactly.
Many people are getting rid of fixed lines for VoIP.. So your company
may have no customers one day if that's how your working!
But on www.ukphoneinfo.com you can search for numbers, and see which
operators own the numbers.
But people now can port there BT numbers to VoIP.. So it's not always
going to be right

You can't easily.
We had the same problem, but worked out that (a) customers ip addresses
didn't match up with the country they had their details in and (b)
things about the order were odd - e.g. name miss spellings.
You should checkout a system like http://www.maxmind.com/app/ccv_overview

A voip number is a landline number. The idea that a number actually
tells you where the caller is located is daft: call diversion and
presentation numbers killed that off years ago.
In what way would a phone number help prevent fraud?
In any event, everyone is moving to VOIP over the next few years. At
present it's only a few tens of thousands per month, but that will
change.

http://www.magsys.co.uk/telecom/codelook.asp might help.

Indeed. Insisting on a conventional style landline sounds like a bad
idea to me (but maybe if I knew the types products/services robert was
offering it might not).

Fraudsters in other countries are unlikely to have a BT number to port
to an ITSP...

I don't know about fraud, but I've heard of them being used for
unsolicited advertising because a) the costs are low and b) it is in
some cases easier to be dishonest with them than with conventional
telephone numbers.

Yes, conventional telephony will go the way of the telegraph. What hath
God wrought!

Yes and no. It's possible to find out who a number block was originally
registered with, but number portability is becoming more common in the
VoIP world and it's not guaranteed. It's unlikely that someone would port
a VoIP number to BT, although it's technically possible. But a BT number
can easily be ported to VoIP.

Start developing alternative anti-fraud methods checks - using a phone
number proves nothing.

How bizarre. Surely a better idea is just to insist that your
customers provide both a Telex number and their inside leg
measurements?
On a serious note, if your security depends on they type of phone
service that your customers use, then you have no security and deserve
no customers.
