SpaceXSI’s Grok Bot agent can now make phone calls on a user’s behalf

Musk first, then the official announcement

Grok Bot’s calling feature first surfaced in a pre-release build. On Oct. 24, an X user wrote that in version 0.77 the bot could dial someone, sit on hold, press keys and get transferred. According to the same post, the user could follow a live transcript of the call at the same time. This was one user’s observation, not a company statement.

On Oct. 25, Musk quoted that post. According to Musk, Grok Bot could now call a person or a business on a user’s behalf and make a request. The bot could also take notes on the response and send a summary of the conversation. Replies that day showed the feature wasn’t available to everyone yet. The v0.77.0 (Oct. 26) and v0.78 (Oct. 27) entries in SpaceXSI’s public changelog don’t mention calling.

The official announcement came from the Grok Bot account on X on Nov. 4 at 6:13 p.m. UTC: “Grok Bot can now make phone calls.” It came with a 42-second demo video, and the post had more than 5 million views as of Nov. 8. SpaceXSI hasn’t said when the feature opened to everyone. Users began trying it on Nov. 3, though some users couldn’t find it in the latest version that day.

How it works: approval, live transcript, summary

In SpaceXSI’s demo video, the user gives the task in chat. Before dialing, the bot opens a “Phone call” card showing the business and the number, with buttons to cancel or call. The call starts only after the user approves it.

During the call, a live transcript scrolls in the chat. The user can take over the call with a “Take over” button or hang up with “End call.” When the call ends, the bot writes a summary, and the demo also shows a recording player at the top of the transcript. One user wrote that a recording of the call arrived when it was over.

The task in the demo is canceling an internet subscription. The customer service agent offers the customer 10% off for a year to stay. The bot declines, saying the customer got a much better deal with Starlink, and completes the cancellation. Starlink is SpaceX’s satellite internet service. The video is a staged demo and isn’t presented as a real call.

The bot speaks in an AI-generated voice, a phrase that also appears in the terms. Voice options aren’t described officially. Under the terms, SpaceXSI may assign users temporary phone numbers to be used solely for calls. The numbers remain the company’s property and can be reclaimed at any time. Official sources don’t say whether the bot can navigate phone menus by pressing keys; that appears only in the Oct. 24 pre-release observation.

Grok Bot can now make phone calls.

It asks the user what it doesn’t know

If the other side asks something the bot doesn’t know, a question card appears in the chat. The user types or selects an answer, and the bot relays it to the person on the line. The call isn’t dropped in the meantime. The card includes a countdown for the reply.

On Nov. 3, Sawyer Merritt shared a 95-second recording of a call, with audio. Merritt’s bot called a person about returning a door handle. When the other side asked where the handle should be shipped, a question card opened in Merritt’s chat. Merritt typed the answer and the bot relayed it. In the post, Merritt described a small answer box that pops up when Grok needs more information, with Grok passing the response to the person on the phone.

Musk quoted the recording that evening: “Try asking Grok @Bot to make calls!” That post had more than 3.8 million views as of Nov. 8. Another user said the bot called a car insurer to ask why a policy renewal went up 14% with zero accidents. When the agent asked a question mid-call, a question card popped up and the user typed the answer. That is the user’s own account.

Sawyer Merritt @SawyerMerritt

Grok @bot's new calling feature is very impressive.

You just tell it who to call and why, and it handles the conversation for you. It shows a real-time transcript of the call, and if Grok needs additional info from you, a little answer box pops up where you type/select your

Haggling: Peter Yang’s call to Comcast

On Nov. 3, Peter Yang, who makes AI tutorials, posted a 15-minute YouTube video. The video description says Grok Bot can now call U.S. businesses on a user’s behalf. According to Yang, the bot called internet provider Comcast (Xfinity) and used rival Sonic’s $49-a-month fiber offer as leverage. When the agent made small talk about the weather, the bot deflected. It said it had no eyes on the sky but guessed it was the usual Bay Area gray.

According to the bot’s summary, the bill dropped from $84 to $45 a month starting that day, and speed rose from 400 to 500 Mbps. The price is locked for a year. The $45 rate depends on autopay; without it, the bill is $55. Yang’s video title says the feature saved $500 a year. Based on the bot’s figures, the difference is $39 a month, or about $468 a year, and it depends on autopay.

At one point, the question card timed out. The bot then said Xfinity had texted a confirmation code but that it couldn’t read Yang’s texts. It asked for the code to be typed into the card to approve the $45 plan, and Yang entered it.

Yang has a promotional tie to SpaceXSI. On Aug. 30, Yang wrote that the company had provided Grok Bot codes to give away, each worth one free month of the $200 Ultra plan. The video description also includes an X subscription code promotion. In September, Yang had also shared how Meta’s Muse agent negotiated $288 in annual savings on a Comcast bill.

The rules: it has to say it’s a virtual assistant

As of Nov. 8, Grok Bot’s documentation has no page on phone calls. The only official text is Section 2.7, “Phone Calls,” added to the Grok Bot Terms in an Oct. 31 update. The previous version, dated Oct. 12, didn’t include it. The same update added an age requirement of 18.

The terms treat calls as “Agentic Actions” and make the user the “caller of record.” The user is solely responsible for complying with the relevant laws, including the Telephone Consumer Protection Act (TCPA). These cover cellular, landline, telemarketing, robocall, caller ID and call-recording rules. Users may only call people who have agreed to hear from them and must obtain all required consents.

Every call identifies itself as made by a virtual assistant on the user’s behalf and may be recorded. Users can’t alter or disable these disclosures. Marketing or mass calls, fraud, harassment, impersonation and emergency services are banned. Calls aren’t a telephone service and can’t be used to reach emergency services. The company may honor opt-out requests, block numbers or regions, and limit or end calls. Users agree to indemnify the company for claims arising from calls or temporary numbers.

The terms also say users agree to receive calls, including in an AI-generated voice, that Grok Bot places on behalf of other users. The terms say Grok Bot may place or receive calls, but no feature for answering incoming calls has been shown.

The disclosure is audible in Merritt’s recording: the bot introduces itself as a virtual assistant calling for Sawyer Merritt on a recorded line about a door handle return. That line doesn’t appear in the transcript of SpaceXSI’s demo video. There, the bot goes straight to saying it is calling to cancel a customer’s internet plan.

On Feb. 8, 2024, the Federal Communications Commission unanimously ruled that AI-generated voices count as “artificial” under the TCPA. The law restricts telemarketing calls, autodialers, and artificial or prerecorded voice messages. FCC rules require prior written consent for telemarketing robocalls. The ruling applies the same standard to AI voices and gives state attorneys general a new enforcement tool. The terms’ explicit reference to the TCPA, the marketing ban and the caller-of-record clause line up with that framework.

Plans, usage limits and open questions

Grok Bot is included in The X Subscription’s Premium ($30 a month or $300 a year), Super ($100 a month) and Ultra ($200 a month) plans. It isn’t available on the $8-a-month Plus plan or the free tier. Premium, Super and Ultra include 4, 15 and 50 times the usage of Plus. Bot activity draws from a weekly pool shared with Grok and Cursor; once it runs out, prepaid credits kick in. SpaceXSI hasn’t said how much of that pool a call uses. It’s also unclear how long calls spent on hold are counted.

Usage limits tightened a few days before the official announcement. TechCrunch reported that over Halloween weekend, some users found their weekly usage unexpectedly maxed out at 100%. On Nov. 1, Musk wrote that the cost of serving Grok Bot was unsustainably high relative to revenue. Musk hasn’t said how the limits will change. According to TechCrunch, a SpaceX filing last month showed the renamed “Super Intelligence” division turning a profit of $431 million.

There’s no official list of countries or numbers; the terms only say the company may block numbers or regions. Yang refers to U.S. businesses, and some users outside the U.S. have asked about the feature. Based on user reports, it can call U.S. businesses for now.

Not every call worked. One user wrote that when the bot called Apple, the rep asked whether it was an AI assistant. According to that user, the rep hung up after Grok said yes, and it happened twice in a row. Other users said a natural gas utility hung up right away and a T-Mobile rep asked to speak with a real person.

AI agents that make phone calls aren’t new

Calling extends Grok Bot’s push to finish tasks on a user’s behalf to the phone. SpaceXSI introduced Grok Bot on Aug. 11, 2026, as always-on agents with their own computers that sign in to tools. The company says the agents finish jobs end to end and only come back when something needs approval. On Oct. 22, the bot began using the Calendar, Reminders and Contacts apps on the phone. Version 0.78 on Oct. 27 added shopping cards and subscription templates. According to the changelog, bots can cancel a subscription or look up its price and renewal date, and check with the user before changing anything.

Google has been testing such calls for years. Duplex, which Google introduced in 2018, called hair salons and restaurants to book appointments. Google said that day it wanted to be clear about the intent of the call so businesses understood the context. Since July 2025, Google Search in the U.S. has offered a “Have AI check pricing” option that calls local businesses about prices and availability. Businesses can manage this in their Business Profile settings. At I/O in May 2026, Google said a feature to call businesses on users’ behalf would roll out to everyone in the U.S. over the summer. It covers categories such as home repair, beauty and pet care.

Meta’s Muse agent launched a feature in September 2026 that calls U.S. businesses. Reuters reported on Sept. 22 that shortly after the rollout began, Meta enabled a “human concierge” test for half its employees. In the test, contractors quietly handled some of the calls. A vice president at Meta Superintelligence Labs wrote that starting the test without proper disclosures was “a miss” and that it had been rolled back for now. According to internal posts, having humans make the calls could raise the success rate to 95% to 98%, compared with a lower rate for AI calling. One employee wrote that an insurance company kept hanging up on Muse after hearing it was AI.
