Muse’s Phone Call Beta Has the AI Agent Dialing US Businesses for You

Meta’s personal AI assistant can now pick up the phone. Muse’s outbound calling beta lets users ask the agent to call US businesses (booking appointments, checking stock, and getting quotes) and reports back with a transcript and summary.

What the Beta Does

On September 16, Meta’s chief AI officer Alexandr Wang posted on X that Meta was expanding the Muse phone-calling beta, as quoted by 404 Media. The same day, Muse principal engineer Ryan Fox posted that the beta for outbound calls to US businesses was widening, prioritizing users who had asked their Muse to be notified first. Phone calling, Fox wrote, was one of the top user requests.

Instead of calling a business yourself, you tell Muse what you need. Muse places the call, handles the conversation on the other end, completes the request, and hands you a transcript and a summary of how it went in the Muse app. An internal Meta memo seen by 404 Media put it this way: “Muse doesn’t just dial a number. It calls a business on your behalf, handles the conversation, completes your request, and reports back with a transcript and a summary.”

Meta began having employees test the calling capability in August, according to internal posts reported by Reuters, then gradually rolled it out to Muse users in the days after the app’s debut. Wang included the phone beta in an October 4 recap of what the Muse team has shipped.

What People Are Using It For

The use cases Meta describes are mundane: booking a haircut, making a restaurant reservation, checking whether a store has an item in stock, and getting quotes from contractors. These are the errands that eat afternoons: the ones involving phone trees and hold music.

Early testers have posted mixed but vivid results. Ravid Shwartz Ziv, an AI researcher at Meta, wrote on X that Muse “called customer service on my behalf. It navigated the phone tree, waited on hold, spoke with a human rep, and resolved the issue (worked great!),” according to 404 Media. Others have reported the opposite: the person on the other end hanging up on the agent, or the call simply failing. That variance is normal for a beta, but it also explains why Meta spent August dogfooding the feature internally before widening access.

The feature fits how Meta has positioned Muse: a personal agent that acts across connected services, not just one that answers questions. Outbound calling is one of the few agent tasks that can’t be done through an API. Many small businesses still run on phone calls, so it reaches places the app otherwise couldn’t.

Still a Beta, With Caveats

Meta frames this as testing, not a finished product. A Meta spokesperson told Reuters the company is “working with merchants to continue improving this potential calling feature, and will only roll it out when it’s ready and with the proper disclosures.” The feature remains limited to US businesses, and availability is still gated. Fox’s post made clear the expansion prioritized users who had registered interest.

After 404 Media and Reuters reported that Meta had quietly used human contractors to place some calls during testing without disclosing it, the company rolled back that human-assisted test phase; a Superintelligence Labs vice president described the undisclosed arrangement as “a miss,” according to Reuters.

For now, the phone beta is Meta’s answer to one of the most-requested agent capabilities (one entry on the longer list of what Muse can and can’t do yet) and a live experiment in whether people will hand their phone calls to an AI. The transcript-and-summary loop is what makes it workable. You don’t have to sit through the call to benefit from it. Whether the beta graduates to a general release will depend on call success rates and the disclosure questions Meta says it’s still working through.
