AI Phone Agents for Small Business: What They Can Do

An AI phone agent can handle routine calls for a small business: calling new leads as they come in, asking your qualifying questions, answering common questions, and passing clean notes to your team. It cannot close a complex sale, calm an angry customer, or make judgment calls. Use it for the first conversation, not the last.

What an AI phone agent is

An AI phone agent is software that holds a spoken conversation on a real phone line. Under the hood it has four parts:

• Speech recognition turns what the caller says into text.
• An AI model decides what to say or do next, following your instructions.
• A synthetic voice speaks the reply.
• A phone connection places or answers the call on a real number.

The agent can also act during the call: look up a customer, book a time, or send the results to your CRM when the call ends. Platforms like Retell AI bundle these parts together, and you pay for each by the minute.

How we use one in our own business

We run CloudWise on the same tools we sell. When a new lead comes in, an AI agent calls them, asks our qualifying questions, and passes the result to us. We built it with Retell AI for the voice agent and a modern automation platform for the steps around it.

That means a lead who fills in a form hears from us while they are still thinking about the problem, and when we call back ourselves, we already know the basics. See the rest of our back office in how we run CloudWise on what we sell.

Good jobs for an AI phone agent

The best jobs are short, repetitive, and follow a script:

• Calling new web leads. Ask the three to five questions you always ask, then book a callback with a person.
• After-hours answering. Take a clear message, answer basic questions, and book a callback, instead of sending callers to voicemail.
• Common questions. Hours, service area, what you do and do not offer, how to book.
• Screening before a transfer. Find out what the caller needs, then pass them to the right person with a summary.
• Confirmations and reminders, with the right consent in place (see the rules below).

What an AI phone agent cannot do well

Be honest with yourself about the limits:

• Complex or emotional calls. Complaints, disputes, and anything that needs empathy should go to a person, fast.
• Negotiation and closing. It can qualify a lead. It should not be setting prices or making promises.
• Decisions that cost money. Refunds, credits, and exceptions belong with your team.
• Hard audio. Bad connections, background noise, and strong accents can lead to misunderstandings. The agent should confirm key details back to the caller.
• Being right every time. AI makes mistakes. Design every agent with a way out to a person.

The way out matters most. Voice platforms support handing a live call to a person. Retell's transfer tool, for example, can do a cold transfer or a warm transfer, where the agent waits for a real person to answer before connecting the caller (Retell AI docs). We design phone and chat agents to say they are an AI assistant up front, and to hand off to a person when asked.

Canadian rules to check before it dials anyone

This is general information, not legal advice. Talk to a lawyer about your specific calling plans before you launch.

Phone calls in Canada are regulated by the CRTC's Unsolicited Telecommunications Rules. Several parts can apply to an AI agent.

Automatic dialing-announcing devices (ADADs)

The rules define an ADAD as automatic equipment that can store or produce phone numbers and is used to convey a "pre-recorded or synthesized voice message" (CRTC Unsolicited Telecommunications Rules). An AI agent that dials people and speaks with a synthetic voice may fit that definition, so plan as if it does.

• Sales calls need express consent. An ADAD may only be used for solicitation if the person gave express consent beforehand, and you must be able to show it (CRTC key rules).
• Other calls must identify you. ADAD calls that are not solicitations must start by saying who the call is on behalf of and what it is about, and give a mailing address and a phone number where a person can be reached (CRTC rules).

Telemarketing rules

• Calling hours. Telemarketing calls may only be made between 9:00 a.m. and 9:30 p.m. on weekdays and 10:00 a.m. to 6:00 p.m. on weekends (CRTC).
• Identify yourself and the purpose of the call at the start.
• The National Do Not Call List. Numbers on the list are off limits for telemarketing unless an exemption applies. One is an existing business relationship, which covers someone who bought from you in the past 18 months or made an inquiry in the past six months (CRTC).

The rules are under review

In June 2026, the CRTC opened a review of the Unsolicited Telecommunications Rules. Among other things, it asks whether the rules should cover AI and synthesized voices more clearly, and whether callers should have to say at the start that the person is not speaking to a live human (CRTC Notice of Consultation 2026-132). Expect changes, and design for disclosure now.

Recording and text messages

• Recording calls. The Office of the Privacy Commissioner of Canada says organizations must tell customers a call is being recorded, explain why, and get their consent (OPC). If your platform records or transcribes calls, say so at the start of the call.
• Text follow-ups. If the agent also sends text messages, Canada's Anti-Spam Legislation (CASL) applies to commercial messages, including consent, identification, and an unsubscribe option (CRTC CASL FAQ).

A safe setup in practice

1. Get consent on your form. Add a checkbox that says a call may come from an AI assistant, and keep a record of it.
2. Disclose at the start. "Hi, this is the AI assistant for Smith Plumbing, calling about the quote you requested."
3. Mention recording if the call is recorded, and why.
4. Offer a person, and make the transfer work.
5. Respect calling hours and the Do Not Call List.
6. Keep records of consent, calls, and opt-outs.

What it costs to run

On our plans, building and running a phone agent is part of the monthly subscription: Core at $3,500 or Scale at $6,000 CAD. AI usage is billed at cost, with no markup.

Usage for a phone agent is billed by the minute. Retell AI, the platform we use, lists pay-as-you-go pricing of $0.07 to $0.31 a minute, depending on the AI model and voice chosen, plus $2 a month for each Retell phone number (Retell AI pricing). Retell is a US company and its page does not name a currency, so budget as if these are US dollars.

A quick example at the top of that range: 200 calls a month at 3 minutes each is 600 minutes, or about $186 (likely US dollars) in usage. Your real cost depends on call volume, call length, and the model. Compare that with what the same calls cost in staff time using our automation ROI calculator.

How to set one up well

1. Write the script your best person would use. The questions, the order, and the answers to common questions.
2. Decide the handoff rules. Which answers mean "book a callback," "transfer now," or "not a fit"?
3. Connect it to your tools. Results should land in your CRM, calendar, or Teams, not in a separate dashboard nobody opens.
4. Test it on your own team first. Have people call it, interrupt it, mumble, and ask odd questions.
5. Listen to the first calls. Read the transcripts every day for the first couple of weeks and tighten the instructions.

Common questions

Will callers know they are talking to an AI?

They should. We design our agents to say they are an AI assistant at the start of the call and to hand off to a person when asked. It is the honest approach, and the CRTC's 2026 review suggests disclosure may become a firm requirement.

Can an AI phone agent answer my main business line?

It can, but start smaller. Put it on after-hours calls or a dedicated line for new inquiries first, with an easy way to reach a person. Once it handles those well, decide whether it should take more.

Is it legal to have AI call leads in Canada?

It can be, if you follow the CRTC's rules: express consent for sales calls made with an automated voice, clear identification at the start, calling hours, and the Do Not Call List. Get consent on your web form and keep a record. This is general information, so confirm your plan with a lawyer.

What does an AI phone agent cost per month?

Two parts: building and running it, which is included in our plans, and per-minute usage, billed at cost. For most small businesses, usage depends mainly on how many calls the agent makes and how long they last, so estimate your monthly minutes first.
