There are also region-specific examples of source-based call routing 
(e.g. 310xxxx in Canada routes to a local instance of a service, for 
some value of "local", at least in Bell Canada's network).

I have Vonage service in Canada with a local 519 area code, and a good 
proportion of the 1-800 numbers I dial using that phone don't work for 
me (either because they're routed through New York to a US-appropriate 
termination staffed by agents who think Canada is a small town in 
Idaho, or because they're not available in the US at all).

So, perhaps this is not a dundi problem at all, but a problem with 
non-uniqueness in the E.164 number space. As such, isn't it just the 
same problem that an individual organisation would work around by 
choosing (say) not to route calls to 1-800 numbers according to 
information obtained by dundi, but instead choosing to send them 
elsewhere?

In other words, if an organisation has its own use for +17009 numbers, 
could it not simply choose to ignore the +17009 route obtained through 
dundi and do something different instead?
