Providers have to take calls without ownership. It's simply not feasible otherwise. Sometimes, I'd be handling calls going from one landline neighbor to another. There's just too many intermediaries. Now, for small, low volume deals, like say, Twilio, yeah you could force an ownership test. But it would have no impact on the real offenders.
