| Telephone carriers bill other carriers for terminating calls to their
subscribers. For instance, let's say that Bell South provides me with
local service to my land-line phone, and let's say that Qwest provides
you with long distance service to your land-line phone. If you call
me, then Bell South will bill Qwest a small amount of money for
terminating your call to my phone. Telephone carriers keep track of
this sort of inter-carrier billing by using a Carrier Access Billing
System (CABS), and the carrier (ie. Qwest in this example) is
identified in the CABS system by their four-digit Carrier
Identification Code (CIC).
Apparently Verizon Wireless is so big that it's right hand doesn't
know what it's left hand is doing. I need to introduce Verizon's
right hand (their legal department) to Verizon's left hand (the people
who maintain the Verizon Wireless CABS system), so that I can find out
which carrier connected a particular call to my Verizon Wireless cell
phone.
Does anyone know anything at all about the CABS system that Verizon
Wireless uses?
