Can't Port from a Particular Rate Center

[Mike Hammett <nanog () ics-il net>]

I first asked on a list much more narrow in scope, but failing to get sufficient data points, I've expanded my scope. 






Assuming the number isn't held by someone exempt from porting, what would prevent someone from being able to port a 
number from a particular rate center in a LATA they have coverage in? 




We picked up a particular carrier for our out-of-area needs and the first thing we throw at them in a LATA we know they 
have coverage in, they can't do. They have a non-useful reason why. It doesn't appear to have moved to a state where 
they contacted the losing provider as the response was very fast, so my provider rejected the port, not theirs. 




When I started at this company (where we do our own porting), I made sure to port a bunch of numbers from all over our 
LATA to see what would happen. All successful. That seems to indicate that it doesn't matter which xLEC or tandem 
currently serves that number, it can move elsewhere.
