Frequently Asked Questions

What is a call clerk?

A call clerk is someone (or something) that handles incoming phone calls for a business. Traditionally, this was a human role. OnCallClerk replaces or supplements that function with AI phone agents that answer calls, respond to enquiries, capture caller details, and take action, all automatically and around the clock.

How does OnCallClerk work?

You sign up, provide your business information (services, hours, FAQs, pricing), and configure how you want calls handled. OnCallClerk gives you a phone number connected to your AI agent. When someone calls, the agent picks up instantly, has a natural conversation, answers questions, and captures the caller's details. You get the full transcript and summary by email or SMS.

Can an AI really handle phone calls for my business?

Yes. Modern AI phone agents use large language models to understand what callers are asking and respond intelligently. They handle follow-up questions, topic changes, and phrasing they have never encountered before. For routine calls (enquiries, bookings, lead capture, information requests), AI handles them as well or better than a human, and it does it instantly, 24/7.

What kind of businesses use OnCallClerk?

Trades companies, dental practices, law firms, property managers, salons, e-commerce brands, accounting firms, IT support companies, and hundreds of other business types. Any business that receives inbound phone calls and wants them handled professionally without hiring dedicated staff.

How much does OnCallClerk cost?

Plans start from $30 per month. Every plan includes a dedicated phone number, 24/7 call handling, full transcripts, and notification delivery. There are no per-call fees, no long-term contracts, and you can cancel anytime.

How long does it take to set up?

Most businesses are live within 10 minutes. You enter your business details, choose a phone number, and your AI call clerk is ready to answer. No code, no technical skills, no waiting for someone to configure things for you.

What if the AI cannot handle a specific call?

You configure fallback behaviour for situations the AI cannot resolve. Options include transferring the call to a team member, taking a detailed message for follow-up, or letting the caller know someone will return their call. The AI never guesses or makes up information.

Can I use my existing phone number?

Yes. You can forward your current business number to your OnCallClerk agent. Callers keep dialling the same number and your AI call clerk answers. You can also use a new dedicated number if you prefer.
