Under the rules, consumers would be able to opt-out of the service if they wished, and carriers must clearly disclose to customers what types of calls may be blocked.
The Federal Communications Commission on Wednesday proposed granting AT&T, Verizon and other telecom carriers clearer powers to block suspected spam calls from ringing consumers' phones, a move that comes a month after robocallers dialed Americans almost 5 billion times, according to one industry estimate.
The FCC claims wireless carriers have not pursued tools that allow calls to be blocked by default because of legal uncertainty about such tools under the FCC's rules.
Currently, consumers often must elect to use carriers' robocall-blocking tools, some of them costing a monthly fee, which means "fewer people are using these services", Pai said.
The call-blocking company YouMail issues estimates of nationwide robocalls each month. The industry is working on deploying this long-in-the-works system, called "STIR/SHAKEN", but it's been a slow process.
Consumers would be allowed to block any callers that are not included in their list of contacts.

Once a user downloads a rival search app, Google also prompts them to change their default search engine in Chrome browser. The investigation is believed to last a year with Google execs expected to be summoned by the CCI soon.
The Federal Communications Commission says it wants to help.
Pai has also been urging phone carriers to adopt an authentication system, dubbed SHAKEN/STIR, which can differentiate between legit phone calls and spoofed ones.
New measures by US regulators could help thwart some of the billions of robocalls received in the U.S. It's not clear if carriers would automatically block those calls, too, said Margot Saunders, senior counsel for the National Consumer Law Center and an expert on robocalls.
"We certainly are encouraging companies to offer this for free", said FCC Chairman Ajit Pai. Carriers like Verizon have anti-robocall tools for subscribers, but they're usually optional and need to be turned on. The FCC will consider the proposal at its June 6th meeting, and if approved, it's hard to say when this will go into effect.
The FCC's efforts come in response to a growing chorus of critics who feel the USA government hasn't acted swiftly or aggressively enough to punish scammers who place unwanted calls or texts to consumers - or prod telecom carriers to improve their anti-robocall technology.
That marks a 46 percent increase from 2017, when users logged about 18 billion robocalls. "People who do robocalls are sophisticated and smart, they will figure out some ways to get around it", said Wired editor-in-chief and CBS News contributor Nick Thompson.
There's little time for the phone companies to get up to speed on the proposal.
