They are obviously aware that the 530-208-9631 has been reported as being utilized in connection with a scam, for I received an identical call to those decribed above (the male caller, who had such a thick SE Asian accent that his English was barely understandable, identified himself as "Justin Johnson" of "Beck Litigation Dept."), but the individuals behind the scam have apparently changed the telephone number they had been utilizing through which to route, and "mask", their calls, as the call I received originated from telephone number 415-251-3769, in Novato, CA (a small city North of San Francisco). I did not respond to the call, but I am concerned that other people might, particularly elderly individuals who are more susceptible to frauds wherein the perpetrators utilize intimidating threats of legal action, so I made a telephonic complaint regarding this call with the Treasury/IRS Administration.  It is unlikely they will take any action, particularly since the calls are probably originating from overseas, and simply being routed so as to make it appear that they are originating in California.
