How do you choose an AI voice agent?

Work down this list and stop at the first "yes".

  1. Do you mostly need calls answered while you're busy? Get an AI receptionist. Per-call plans (Smith.ai, Upfirst) suit fewer, longer calls; minute bundles (Rosie) suit many short calls; per-customer billing (Goodcall) suits callers who ring back often.
  2. Are most calls bookings? Check the calendar integration before anything else.
  3. Do you need a human fallback? Smith.ai can transfer to live receptionists, and Rosie adds warm transfers on its $149 Scale plan.
  4. Handling patient information? Ask for a signed BAA before you sign up. Several small-business pricing pages don't mention one.
  5. Do you run a contact center on Genesys, Five9, Zendesk or Salesforce? Shortlist the enterprise support platforms and expect a sales-led contract.
  6. Do you want to call leads? Get written consent first, then pick an outbound tool.
  7. Do you have developers? Use a per-minute platform and budget for model, voice and phone costs on top of the headline rate.

What's the best AI receptionist for answering calls?

Which AI voice agent books appointments?

Clinics need more, like a BAA and practice-software links: see Best AI receptionists for dental and medical clinics.

What's best for customer support at scale?

Amazon Connect, Google, Decagon, NiCE Cognigy and mid-market options: AI for customer support phone lines: best options.

Which AI voice agents make outbound sales calls?

Check the law first. The FCC ruled in Feb 2024 that AI-generated voices count as "artificial" under the TCPA, so calls to cell phones and home lines need the called person's prior express consent, and written consent if you're selling (FCC). Point these tools at leads who asked to hear from you.

Retell also runs batch calling campaigns (Retell pricing), and Vapi has outbound campaigns (Vapi docs). Costs and the legal detail: Can an AI agent make sales calls for you? Tools, costs and the legal catch.

FAQ

What is the best AI voice agent for a small business?

It depends on the job. To answer calls, Smith.ai (AI with live human backup), Goodcall (no metered minutes) and Rosie ($49 a month) are good starting points. To book appointments, Upfirst says it books into Google Calendar, Outlook, Calendly and more. Prices as of 14 Nov 2026.

How much does an AI voice agent cost?

As of 14 Nov 2026, paid plans for small-business AI receptionists start at about $25 to $150 a month. Developer platforms charge per minute: Vapi $0.05 plus model costs, Retell $0.07 to $0.31, Bland $0.14. Most enterprise support platforms quote through sales.

Can an AI voice agent make sales calls?

Yes. Bland, Thoughtly, Regal and Retell market outbound calling. In the US, the FCC treats AI voices as artificial under the TCPA, so calls to cell phones and home lines need prior express consent, and written consent for sales calls. Don't use them to cold-call consumers.

Which AI voice agents will sign a HIPAA BAA?

As of 14 Nov 2026, Vapi sells a $2,000-a-month HIPAA add-on with a BAA, and ElevenLabs, PolyAI and Upfirst offer BAAs on Enterprise only. Retell says you can sign its BAA without an Enterprise plan. Bland's FAQ says it signs BAAs, but its plan table shows the BAA on Enterprise only. Get it signed before patient data flows.
