As glitchedpixel noted, a fair number of these calls originate overseas using VoIP services. The call centers spoof telephone numbers when making their calls. It is virtually impossible to accurately block their calls. Many times, these boiler room outfits will spoof working telephone numbers, so, RBOCS and cellular service providers would run the risk of blocking legitimate telephone numbers. This also holds true for spoofed mobile telephone numbers, I, myself, receive more than a fare share of spoofed legit cellular telephone numbers on my smartphone and landline.

Verizon Core (Ma Bell) has been identifying potentially bogus calls for a while now. When a suspect telephone number is received on a Verizon Core landline, the word "Spam" is passed along as a part of Caller ID in addition to whatever other information is contained in the LIDB.

Other RBOCs such as at&t, FairPoint and CenturyLink may provide a similar service.
