PS. I generated a list of Onvoy blocks from their OCNs in every LATA and 
blocked them all on my business number for a while, which led to a 100% 
decrease in spam calls. The problem is, legitimate VoIP providers use 
them for origination too, of course. Otherwise, they seem to be the 
herpes of the PSTN.
