Fraud calls are not just voice clones. They are scripts: routing numbers, wire instructions, verification codes, payroll changes, password resets, and urgent pressure. Vicall detects synthetic audio in real time and can optionally alert on risky call language — on-device, with no call audio stored.

Vicall is building the most complete public resource on AI voice cloning, vishing, payment fraud, risky call scripts, and the controls that stop employees from acting too fast. Start here.
A UAE bank lost $35 million in a single CEO voice fraud call. A UK energy firm lost $243,000. These are documented, confirmed cases — not projections.
Capital calls, closing wires, and vendor payments are routinely discussed by phone. Attackers do not always need a perfect clone — they need an employee to say yes to a routing number, account change, or urgent payment instruction.
AI voice cloning attacks grew 2,400% year-over-year. No other fraud vector is growing at this rate. Every executive with public audio — earnings calls, podcasts, conferences — is a cloning target.
Organizations have extensive controls for email. They have almost none for live phone conversations. Caller ID, familiar voices, urgency, and financial keywords still reach employees with little real-time context.
Vicall is a secure calling app with built-in call-risk detection. It flags AI-generated voices and can alert on high-risk phrases like routing numbers, verification codes, wire instructions, gift cards, and password resets.
Finance teams, PE/VC operations staff, law firm bookkeepers, AP departments, front desks, and office managers — anyone who receives phone instructions involving money, identity, account access, or sensitive data.
AI voice cloning generates a convincing replica of any person from 3 seconds of audio — in real time, on a live call. But social engineering also works with a real human voice: an urgent wire, a new routing number, a payroll change, a password reset, a one-time code. Most business phone systems give employees little context while the call is happening.
Vicall is a secure calling app with built-in call-risk detection. Employees get real-time synthetic-audio verdicts plus optional phrase alerts when a call crosses a policy line — for example "routing number," "verification code," "gift card," "wire transfer," or "reset your password." MSPs deploy it via invite codes; businesses can sign up directly in minutes.
Whether you're protecting your own business or deploying for dozens of clients, setup takes minutes — not days.
Create your company account, link billing, open the simple business portal, and invite your team. They download the app, enter the code, and every call is protected with voice-clone detection plus optional risk phrase alerts — in under 5 minutes total. $25/seat/month.
One MSP portal. Deploy the Vicall app to mobile teams or drop a Mac Mini on-premises for office landlines — or both. Configure client-specific phrase alerts for social-engineering risk. $15/seat/month wholesale. You set the margin.

How CEO voice fraud, wire transfer scams, and closing wire theft work — and the controls that slow them down before employees act. Written by the Vicall team.
AI voice fraud is a fast-moving space. Here are the precise definitions of the terms you need to know.
The use of machine learning to synthesize a convincing replica of a specific person's voice from a short audio sample — as little as 3 seconds. The cloned voice can speak any text in real time and is acoustically indistinguishable from the original. Used in phone scams to impersonate trusted contacts.
A phone call in which the caller's voice has been synthesized or replaced by AI to impersonate a real person. Deepfake phone calls are the primary delivery method for AI voice cloning scams, targeting victims who trust the person being impersonated.
Any technique used to make a caller sound like a different person. Includes AI voice cloning, voice conversion models, text-to-speech impersonation, and replay attacks. Distinct from caller ID spoofing, which fakes the phone number rather than the voice.
The falsification of the phone number displayed to the call recipient, making the call appear to originate from a trusted number such as a bank, government agency, or family member. Caller ID spoofing attacks have risen 340% and render the displayed number meaningless as a trust signal.
The process of identifying AI-generated speech artifacts in live call audio. Instead of asking who the speaker is, synthetic-audio detection answers whether the voice itself was machine-generated.
A live probability value representing how likely incoming audio is synthetic. Lower scores indicate human speech patterns, while higher scores indicate likely AI-generated speech and trigger alert states.
Machine learning inference performed locally on a user's device rather than transmitted to remote servers. On-device AI enables real-time processing with complete privacy — no data leaves the device. Vicall uses Apple's Neural Engine and CoreML to run voice clone detection entirely on-device.
The use of voice-based impersonation to psychologically manipulate a victim into taking an action — wiring money, sharing credentials, or disclosing private information. AI voice cloning has made voice social engineering dramatically more convincing and scalable. Attacks are up 890% year-over-year.
How Vicall works, how MSPs deploy it, and what it means for the businesses you protect.
Vicall is voice fraud and social-engineering protection for business calls, available as two products. The Vicall App runs on-device AI during live calls and gives employees real-time synthetic-audio verdicts plus optional phrase alerts for risky language like routing numbers, passwords, verification codes, wire transfers, and gift cards. Vicall Landlines adds the same protection to existing office phone systems via a Mac Mini on-premises, then sends the answer to the team's phones — no new numbers.
Vicall's on-device AI model analyzes incoming call audio for synthetic markers — artifacts and patterns that distinguish AI-generated speech from a real human voice. The same on-device call-risk layer can also alert on configured social-engineering phrases. It catches 90–95% of AI voice clones that would fool a trained employee, while phrase alerts help employees slow down when a caller asks for a routing number, one-time code, password reset, gift card, or wire instruction.
Vicall deploys as a managed service through your portal. Businesses sign up directly into a simple company portal; MSPs create a company for each client and issue company invite codes. Employees install Vicall, enter the code, and they're protected — no complex integration, no voiceprint enrollment, no training period. It works from the first call. For clients with office phone systems, you can also deploy Vicall Landlines — a Mac Mini that adds on-premises detection to their existing phones and sends verdicts to the team's phones.
Any business where phone-authorized transactions carry financial risk. The highest-value deployments include law firms (trust account disbursements, closing wires), PE/VC firms (capital calls, deal wires), corporate finance and AP teams (wire transfers, vendor payments), and real estate (closing disbursements). These are the businesses where a single fraudulent call can mean millions in losses.
AI voice cloning uses machine learning to synthesize a convincing replica of a person's voice from as little as 3 seconds of audio. The cloned voice can be used in real-time phone calls to impersonate anyone — an executive, a client, a partner. In 2024, over 3.1 billion deepfake voice calls were placed worldwide, costing businesses $25 billion annually. These clones fool trained employees 90–95% of the time.
Vicall's synthetic-audio model runs on the device's Neural Engine, keeping clone detection fast and private during the live call. The product is built for MSP-controlled client deployments where sensitive-call workflows need clear verdicts and minimal operational exposure.
No. Vicall detects synthetic audio — not specific speakers. There are no voiceprints to build, no contacts to enroll, no training period. The detection model works from the very first call. If the incoming audio is AI-generated, Vicall flags it regardless of who the caller claims to be.
AI voice fraud and phone-based social engineering are the attack surface your clients have not instrumented. Vicall gives you a new managed service to offer: voice clone detection plus optional risk phrase alerts for every sensitive call your clients take. It's another security layer, another recurring revenue stream, and another reason clients stay with you. App deploys in minutes via invite codes. Landline detection deploys via a Mac Mini on-premises and sends verdicts and alerts to the user's phone.
Callback verification fails when the attacker has spoofed the caller's number — your callback reaches the attacker. Dual authorization can be socially engineered. Both happen after the employee has already been convinced by the voice. Vicall operates during the live call — detecting synthetic audio before the employee acts on any instruction. It's a fundamentally different layer that works where process-based controls break down.
