Re: Phone# w/my FIOS said "No such number" for school

Only way for a route to change is a LERG Update or porting request. If not Switches don't get updated like Ever.... Could there have been a mistype somewhere in the School Provider's system, sure.

This is correct, when an update to the LERG is made then we will see updates made. For instance, say the NY metro area added a new NPA-NXX, the LERG will require all providers to update their switches to route accordingly. Of course you will find one or two telecoms that either didn't update their switch or put in the update but made a mistake somehow.

Just an FYI., this website is specifically used for caller ID. This wouldn't indicate if your phone number is provisioned properly.

There is no such thing a 100% certainty, but if the site does an SS7 dip and finds the DN then there's a 99.9% chance that the line is provisioned.

I see many instances where a block of numbers are exchanged between providers and mistakenly give a few subscribers numbers with it. i.e. John has at&t and his number fall in this line range - 555-220-xxxx. Then the company exchanges that entire line range to sprint. Now John can't receive any calls and is putting in a trouble ticket.

When someone does a query into the NPAC database, we see the number now belongs to sprint. This typically doesn't happen on a large scale, but it happens.

Careful: tnid.us shows you the 'original' carrier. I'm with Vonage at the moment, and it indicates original carrier was Verzon (which it was, but its not now...) Same thing with my mother's number; she's with Cavalier Telephone, and 'original carrier' is Verizon.
