Well, to be more specific ...

Most facilities-based CLECs have at least 3 kinds of trunks[0]:

* Local
* "RBOC" Long Distance
* IXC

Local trunks are designed for callers for whom the call is local.  "RBOC 
Long Distance" trunks are trunks going to the RBOC, but terminating a 
call that is long distance (ie, in-state long distance).  IXC trunks are 
for "pure" long distance calls.

The RBOC and CLEC calling areas are often different.  Therefore, the 
RBOC cannot make the same kind of "blanket assumptions" about CLEC 
trunks that they can PRIs they've sold to end users.  RBOCs generally 
"lock down" end user PRIs pretty tightly.  On the other hand, 
facilities-based CLECs generally have a fair amount of latitude. 
Wireless carriers have even different rules than the CLECs...

If an RBOC sees large numbers of "out of area" ANIs coming through a 
CLEC's local trunks, it would be in the interest of the RBOC to bring 
this to a halt.  While this might be a gray area ... I'll repeat my 
original assertion.  I'd rather not find myself "holding the bag" while 
the regulators duke it out.
