T-Mobile is among the first U.S. telecom companies to announce plans to thwart pesky robocallers. From a report on VentureBeat: The move represents part of an industry-wide Robocall Strike Force set up by the Federal Communications Commission (FCC) last year to combat the 2 billion-plus automated calls U.S. consumers deal with each month. Other key members of the group include Apple, Google, Microsoft, and Verizon. T-Mobile's announcement comes 24 hours after the FCC voted to approve a new rule that would allow telecom companies to block robocallers who use fake caller ID numbers to conceal their true location and identity. From a report on WashingtonPost: The Federal Communications Commission on Thursday proposed new rules (PDF) that would allow phone companies to target and block robo-calls coming from what appear to be illegitimate or unassigned phone numbers. The rules could help cut down on the roughly 2.4 billion automated calls that go out each month -- many of them fraudulent, according to FCC Chairman Ajit Pai. "Robo-calls are the No. 1 consumer complaint to the FCC from members of the American public," he said, vowing to halt people who, in some cases, pretend to be tax officials demanding payments from consumers, or, in other cases, ask leading questions that prompt consumers to give up personal information as part of an identity theft scam.
