In my view, if an intermediate carrier is refusing to route the call, they are in clear and direct violation of the FCC's recent orders. In October, the FCC made it quite clear that incorrect, incomplete, or otherwise untraceable billing information is not a basis for call blocking.
You may be right in terms of an intermediate carrier blocking it to a non-toll-free destination number. What about the terminating toll-free carrier? Do the FCC's orders specifically apply to calls terminating on a toll-free number? These are treated differently from conventional lines in that the callee pays the freight and caller-ID blocking is supposed to be ineffective. A carrier could argue that TF numbers aren't capable of origination so any call claiming to originate from one is by definition fraudulent and therefore not valid. This would be particularly true if the called party is the one paying for the call. Are carriers required by FCC to deliver fraudulent calls? In any case, the destination end user can certainly refuse it. This is particularly true if the terminating number is toll-free and the ANI is missing or populated with a spoofed TF origin. I'm not sure if this is still the case but within the last year Verizon's customer service number of 800-483-2000 would not accept calls coming from a toll-free CLID and the reason for the failure wasn't readily apparent to the caller. I believe it gave a "call cannot be completed as dialed" intercept. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
