A problem is in all the definitions.
Everybody is a "carrier".
 
ILECS, CLECS and CMRS Carriers are the three major local types.
IXCs are a fourth non local type.
 
Telco is a term usually implying an ILEC, but after all, a CLEC would like their customers to think of them as the "Telco".
 
Every carrier sets its own Rating point for its NXXs.
 
The ILECs don't like what the CLECS and CMRSs do in that regard.  They try to insist that the other Carriers match thier rate centers.
 
The other carriers are not required to by law.  Particularly CMRS carriers which are specifically granted "freedom" by the FCC in that regard.
 
This leaves the ILEC and particularly the smaller "independent" ILEC viewing any transport outside if their local service area as "toll", requiring facilites that they buy from someone else.
 
A larger ILEC, (SBC) may regard a call from Rate Center "A" to "B" as toll for billing purposes, but be running it through their own Tandem (Big Central) switch on the way to "B" anyway, and not be paying anyone for anything.
 
Both CMRS and CLEC Carriers have an "absolute" right per the FCC to receive calls at the Tandem that "feeds" a Local Office, ie. they can receive calls from any Local Exchange that Subtends the Tandem.
 
This works fine for the Big ILEC,  It is their Local office, it its their Tandem, they route calls that way any way for either local or "Toll" calls so they give the Calls to competative carriers at that point.  Various CLECS and CMRS carriers also usually exchange calls there between themselves.
 
But the small ILEC (island in the country side) say "we have to route calls over 'toll facilities' to do that."
 
But they are only toll facilites because the choose to call them that.  One can just as well call them "interoffice connection facilites" and they are a normal cost of doing business.  They may not have been before there was competition, but in order to have competition, everybody has to meet at someplace.  It isn't fair to make everyone else meet at every ILECs front door.
 
So yes it gets ugly sometimes.  It is very ugly in Texas at the moment, but the FCC is currently giving a great course in "total beauty makeovers" with the rulings that were issued Thursday or Friday and Monday

There lies the problem Gary.  It�s possible for a carrier to �define� a rate center different from a �POP�.  (The telco industry does not believe this should be allowed) Often, the carrier will have no connectivity to the �rate center�, meaning calls that really do originate from the �rate center� must travel over toll facilities to reach the �POP�.

 

It is ugly indeed.

Get a NANPA database subscription and compare the rate centers.

My only point I guess is that if you are in a position where you are handed a list of number from a network provider which owns them it's tough to know if they handed you some bum numbers on that list.

This would be true. 

 

However, we have had many occurrences of the carrier presenting these numbers as �local�  to the end user without ever checking with the telco (when indeed they were not local calls).   I speak from both sides of the issue   (telco/isp)  J

 

In these cases, it�s pretty clear that the carrier has an issue.
