color=#0000ff size=2>In the NANP, toll free numbers (aka 800 numbers) are known
as non geographic numbers, but geographic routing may still apply (by country),
resulting in non routability in the 800 number pool. Interexchange carriers can
also play routing games with 800 numbers based on a number of factors, including
origin, time, etc.</FONT></SPAN></DIV>

Uhm, I'm not in the US, so correct me if I'm wrong, but in the Netherlands, the least
thing you can expect is that a 0800 number belongs to one organisation. Therefore, if
this organisation chooses to publish the number through DUNDi, they should never
have to expect conflicts with other organisations. They control the route (as they
should) and they can decide wether or not to deal with it in a certain way. We can also
choose what to do with 0800 numbers called by mobile users. This has two purposes:
the cost to accept the call is higher, but also we can route differently based on the
fact we have no clue about their whereabouts.
I don't think this is a problem. People disclosing 0800 numbers through the e164
context in DUNDi should consider callers coming in on this route as 'roaming'. No
assumptions on whereabouts can be made.
Or am I missing something here ?
</PRE></BLOCKQUOTE><BR>Yes, if Robert is correct, what you're
missing is that "The problem with 800 numbers is that they are not
unique". So, for example, you could have a number +1 800 234 5678 which
goes to one company when called from some US states, but goes to another
company when called from other US states.<BR><BR>I don't know if that is
(still?) correct, but I do remember in the past my family's business needed to
have a separate toll-free number for callers in 49 states, and a different
number for callers in our home state, and that callers using the wrong one
would not get through.<BR><BR>I'm not sure if those numbers which were for
in-state calls only were assigned to different entities in other
states.. It seems pretty insane to do that, but who knows. 5
minutes of googling didn't seem to give me an
answer..<BR><BR>-SteveK<BR><BR></BLOCKQUOTE></BODY></HTML>
