Wheeler wrote on the commission's website:

"In regard to the Commission's expectations that carriers respond to consumers' blocking requests, I have sent letters to the CEOs of major wireless and wireline phone companies calling on them to offer call-blocking services to their customers now -- at no cost to you."

According to Consumerist, he sent the letters to AT&T, CenturyLink, Frontier, Sprint, T-Mobile, US Cellular and Verizon. The ball is now in their court, and it's up to them to grant the chairman's request.

Wheeler also sent letters to intermediary carriers, companies that connect calls from internet services like FiOS to carriers' lines. He asked them to retain the original caller ID info for calls made through those services, since spammers and scammers typically spoof their phone numbers. Consumerist says the letters asked those companies to create a list of local entities regularly impersonated by robocallers. That would make it easy to flag and block suspicious calls, especially those made from outside the United States.
