Digital Trends - Spam has been a scourge of email for decades—but even before that, unsolicited telemarketing calls were the bane of the phone system. That plague of unwanted marketing calls has proceeded into the digital age, with services like Google Voice sometimes being inundated with calls from telemarketers. Now, Google has rolled out a new spam filtering tool for Google Voice that will automatically route calls, voicemail, and texts Google thinks are spam to a user’s spam folder. The filtering system is based on Google’s own spam identification tools, as well as feedback the company receives from Google Voice users reporting spam in Google Voice.
