I Tested 3 Ways to Add an AI Receptionist to My Business Phone

I wanted an AI that could answer calls and reply to texts when my team could not. There turned out to be three real ways to get there, and I tried to be honest about what each one costs: in money, in time, and in attention. Here is what I found, what each route is good for, and the questions that decided it for me.

What an AI receptionist actually does

• Answers the phone in a natural voice and holds a real conversation, not "press 1".
• Answers questions from what you teach it: services, prices, hours, directions.
• Books appointments into your calendar, if you connect one.
• Hands over to a person when the caller needs one, or takes a message.
• Replies to texts the same way, either automatically or as a draft for you to approve.

Option 1: Build it yourself

Genuinely possible, and I proved it to myself by doing it. It works. What it took: connecting a phone number to a speech pipeline (speech to text, a language model, text to speech), keeping answers short enough for a phone call, handling interruptions, writing the hand-over to a person, and building a way to check what it says before trusting it on its own. Closer to a few focused days than an afternoon, and it needs attention every time your business's answers change.

Best for: developers who want full control and enjoy the upkeep.

Option 2: Hire someone

Gets you out of the hands-on work, but not out of the relationship. Every change to your hours, prices or services becomes a request to someone else, on their timeline. Agencies and freelancers often build on a voice AI platform and charge for setup plus a monthly fee, with the platform's per-minute cost on top.

Best for: businesses with unusual needs and a budget for ongoing help.

Option 3: Use one that is already built

The honest trade-off is control versus speed. You give up some low-level flexibility and get a working receptionist in minutes: a knowledge base you fill with your own content, calendar booking, transfers to your team, and a Draft mode that lets you approve every text reply until you trust it.

Best for: most small businesses that want it working this week and rarely want to think about the plumbing.

The three side by side

The questions that decided it

1. How much ongoing attention do I want to give this? This mattered more than price.
2. Does it run on the number I already have? Moving numbers to get an AI is a big ask.
3. What happens when it does not know? It should hand over or take a message, never invent an answer.
4. Can I review texts before they go? A draft mode is the safest way to start.
5. What does it cost when it is busy? Look at how minutes and messages are counted, and what happens when you run out.

Getting started safely

• Start with your real questions. Write down the ten things callers ask most, and teach those first.
• Use draft mode for texts for the first couple of weeks and approve each reply.
• Set clear hand-over rules. Anything about billing disputes, emergencies or complaints should go to a person.
• Start with after-hours. Let the AI cover the night while your team covers the day, then widen it.
• Read the transcripts each week and fix the answers it got wrong.

A week-one plan

1. Day 1: add your top ten questions and answers, your hours, and your services to the knowledge base.
2. Day 2: set transfer rules: who gets which kind of call, and what happens when nobody answers.
3. Day 3: turn it on for after-hours calls only, and texts in Draft mode.
4. Days 4 to 6: read every transcript and draft. Fix any answer it got wrong in the knowledge base.
5. Day 7: decide whether to widen it to busy daytime hours, or move texts to Auto mode.

Common worries, answered

• "Will callers know it is an AI?" Some will, and that is fine. Many prefer a quick, accurate answer to voicemail. Being upfront builds trust.
• "What if it says something wrong?" Limit it to what is in your knowledge base, read the transcripts, and keep sensitive topics for people.
• "Will it replace my team?" It covers the gaps: nights, weekends and busy hours. The conversations that need a person still reach one.

Where TelBuddy fits

TelBuddy is option 3, on the Twilio or Telnyx number you already own. The AI receptionist is an optional add-on to any plan, from $19.99 a month for 2,000 AI messages and 100 AI voice minutes, with larger allowances on AI Growth and AI Business. It answers calls and texts from your knowledge base, books into Google Calendar, transfers to your team or a queue, and offers Draft or Auto mode for texts. If AI minutes run out, after-hours callers go to voicemail rather than being turned away.

What actually mattered

The real question was never "which is cheapest". It was "how much ongoing attention do I want to give this". Building it myself gave the most control and the most upkeep. Using something already built traded a little flexibility for never thinking about the plumbing again, which, for a business owner, was the point.
