Ajit Pai and the FCC’s commissioners are growing as incensed and fed up with robocalls as the rest of us. Today, Pai sent a letter to over a dozen US mobile providers urging them to deploy an industry-wide method of combatting the automated nuisance calls — or else. “By this time next year, I expect that consumers will begin to see this on their phones,” Pai said in a press release.

“Carriers need to continue working together to make this happen and I am calling on those falling behind to catch up.” He added that “if it does not appear that this system is on track to get up and running next year, then we will take action to make sure that it does.”
