Restaurants Are Losing $20 Billion a Year to Missed Phone Calls. AI Is Finally Fixing It.

Between 5 p.m. and 8 p.m. on any given weeknight, the average restaurant misses roughly a third of its incoming phone calls. The line is ringing while the host is seating a four-top, the kitchen is firing tickets, and nobody has a free hand to pick up. Most of those callers never try again.

This is not a new problem. What is new is the math. According to an analysis published in QSR Magazine using TouchBistro research and National Restaurant Association location data, the U.S. restaurant industry loses an estimated $20 billion annually from unanswered calls. At the unit level, that translates to roughly $28,700 per restaurant per year in unrealized revenue from missed phone orders, reservations, and catering inquiries.

The figure is built on conservative assumptions: 700,000 U.S. restaurant locations, an average of 18 missed calls per day, and 60% of those calls carrying real purchase intent. The actual number may be higher. Independent analysis from Breez found that 43% of all restaurant phone calls go unanswered. Slang AI's proprietary dataset, drawn from millions of calls across its restaurant customer base, shows the figure climbing to 60% during peak service hours.

For operators who have spent the past two years focused on drive-thru AI, kiosk upgrades, and third-party delivery optimization, the phone has been hiding in plain sight as the highest-ROI channel to fix.

Why Phone Calls Still Matter

The instinct to dismiss phone ordering as a legacy channel is wrong. Phone callers represent some of the most valuable customer interactions a restaurant can have.

Data from Active Menus, a restaurant technology research firm, shows that phone order customers spend 18% more per order than online customers and are 2.3 times more likely to become repeat customers. HungerRush, which provides AI ordering to QSR concepts, reports that the average quick-service location receives 50 to 75 phone calls per day, with 8 to 10 calls arriving simultaneously during peak periods.

Slang AI's 2025 State of the Restaurant Phone Report, covering millions of calls across its platform, found that 71% of all restaurant phone calls are directly tied to revenue: orders, reservations, private dining, and catering inquiries. A full 34% of those calls come in outside business hours, when no one is available to answer at all.

"Operators have long viewed their phones as an essential communication channel, but they may not realize their full potential," Alex Sambvani, CEO and co-founder of Slang AI, said in the report. "Our data definitively shows that missed calls lead to lost revenue."

The gap between what the phone could generate and what it actually generates is the opening that a new class of AI vendors is racing to close.

The Vendor Landscape in 2026

The AI phone ordering market for restaurants has moved quickly from a handful of startups to a competitive field with distinct segments: purpose-built phone AI platforms, voice AI companies expanding from drive-thru into phone, and POS-integrated solutions that bundle phone answering into broader tech stacks.

Maple is the newest entrant drawing attention. Founded in December 2023, the New York-based startup has already answered more than 1 million restaurant calls with a 94% resolution rate (meaning no human handoff needed) across 2,500 merchant locations. On March 16, 2026, Maple announced a direct integration with Shift4's SkyTab POS system. The integration is available immediately to all SkyTab merchants and deploys in minutes: orders taken by phone AI flow directly to kitchen display systems and receipt printers with no manual re-entry, no extra tablets, and no separate menu programming required. Maple's system pulls live menu data from SkyTab in real time, including items, modifiers, prices, and availability.

"Restaurant owners constantly tell us that they can't afford to hire dedicated phone staff, but they also can't afford to miss calls," Maple CEO Aidan Chau said in the announcement. "Orders flow straight to the kitchen without extra tablets, duplicate entries, or friction."

SoundHound AI (Nasdaq: SOUN) has the largest enterprise footprint. Known initially for its voice technology in automotive, SoundHound has expanded aggressively into restaurant phone and drive-thru ordering. Its most significant deployment is at Red Lobster, announced September 2025, where SoundHound's phone ordering AI now operates across approximately 500 locations. The system handles the full menu, processes multiple simultaneous calls, and routes customers to a live agent on request. SoundHound's restaurant client list also includes Beef O'Brady's, Torchy's Tacos, and Peter Piper Pizza.

"SoundHound is seeing huge demand for our AI-powered voice ordering services," Ben Bellettini, SVP of Restaurant Sales at SoundHound, said at the time of the Red Lobster announcement.

ConverseNow operates at the highest volume of any vendor in the space, processing more than 2 million conversations per month across 1,200 restaurant locations. The company reports that its platform has repurposed 83,000 labor hours monthly, shifting staff from phones to higher-value tasks in the kitchen and dining room.

Kea has carved a niche in accuracy and upselling. Deployed at Blaze Pizza and Newk's Eatery, Kea reports a 99.3% order accuracy rate and a 25% average increase in order value. The system's setup takes less than an hour per location, which reduces the friction that keeps multi-unit operators from rolling out new tech.

Loman AI, the Austin-based startup whose analysis underpins the $20 billion industry loss figure, raised $3.5 million in funding in 2025 and targets independent restaurants. Its own call processing data suggests that 81% of missed calls represent actionable revenue, a figure even higher than the 60% used in the conservative $20 billion calculation.

The ROI Math Operators Should Run

The business case for AI phone ordering is more straightforward than most restaurant technology investments.

Consider a 15-unit franchise operation where each location misses an average of 18 calls per day (a figure consistent across multiple vendor datasets and the QSR Magazine analysis). Using an average takeout order value of $38, per TouchBistro research, and a 60% conversion rate on answered calls:

That is 10.8 recoverable orders per location per day, or roughly $411 per location. Over a month, each unit recovers approximately $12,300 in revenue that was previously going to voicemail or dial tone. Across 15 locations, the annualized recovery is approximately $2.2 million.

AI phone ordering systems typically run a few hundred dollars per location per month, depending on the vendor and call volume. Even at $500 per location (the high end of current market pricing), the monthly cost of $7,500 across 15 units generates a roughly 25-to-1 return on recovered revenue.

Those numbers explain why the Qu 2026 State of Digital benchmark report, surveying 168 restaurant brands operating 91,000 locations, found that voice ordering ranks third among AI investment priorities for restaurant operators. Thirty-nine percent of brands with AI budgets are directing spend toward voice ordering systems, behind only marketing/CRM personalization (53%) and predictive analytics (40%).

The broader AI adoption picture, however, reveals a cautionary pattern. While 73% of restaurant brands are now investing in or planning AI initiatives, only 9% report meaningful or transformational impact from those investments. Forty-three percent say the value so far has been limited. That disconnect between spending and results is driven largely by fragmented tech stacks: 37% of brands say disconnected systems prevent them from getting full value out of technology investments.

Phone AI may be the exception that proves the high-ROI case precisely because the integration is simpler. Unlike drive-thru AI (which requires outdoor hardware, speaker systems, and environmental noise handling) or kitchen robotics (which requires physical installation), phone AI is a software layer that plugs into existing POS infrastructure. Maple's SkyTab integration takes minutes. Kea's setup takes under an hour. There is no construction, no lane reconfiguration, and no new hardware to install.

What Red Lobster's 500-Location Deployment Reveals

Red Lobster's rollout of SoundHound across its entire post-bankruptcy footprint is the largest single-chain AI phone ordering deployment to date and the best available case study for what happens at scale.

The chain was under financial stress when it made the decision, which is precisely why the deployment matters. Red Lobster did not invest in AI phone ordering as a nice-to-have innovation project. It deployed it as a cost-reduction and revenue-recovery tool during a turnaround in which every dollar mattered.

Red Lobster COO Larry Konecny framed the system's value in terms of guest experience, not cost cutting: "We're able to streamline the takeout process to make ordering faster and easier for our guests."

That framing is notable because it signals how enterprise chains are positioning phone AI to their front-line staff: not as a replacement for workers, but as a way to stop phone interruptions from degrading in-restaurant service. When a host stops seating guests to answer a phone, or a server puts a table on hold to take a call-in order, the cost is not just the missed call. It is the slower table turn, the longer wait, and the diminished experience for the guests already in the building.

Where This Goes Next

The phone AI market is consolidating quickly. SoundHound, already public on Nasdaq, has the balance sheet and brand partnerships to scale at the enterprise level. Maple's POS integration strategy (building direct connectors to SkyTab, with other POS systems likely to follow) positions it for mid-market and independent restaurants that want activation without an enterprise sales process. ConverseNow's 2 million monthly conversations give it the largest training dataset for improving accuracy over time.

The integration that matters most in 2026 is POS connectivity. AI phone ordering only works if the order appears on the kitchen line without anyone touching it. Maple's Shift4 integration, SoundHound's direct POS connections at Red Lobster, and Kea's self-service setup all point in the same direction: the systems that reduce operational friction at installation will win the deployment race.

For operators who have not yet evaluated phone AI, the starting point is simple: measure your missed calls. Most POS systems and phone providers can generate a report showing answered versus unanswered calls by hour. If the data shows you are missing more than 20% of calls during your peak service window, you are likely leaving $25,000 or more per location per year on the table.

At that price, the phone is not a legacy channel. It is an unoptimized revenue stream, and the tools to fix it are now cheap, fast to deploy, and proven at scale.
