How to Set Up an AI Receptionist (Step by Step)
What to prepare, the setup steps in order, how long each stage takes, and why most owners start on overflow and after-hours calls first.
Setting up an AI receptionist means teaching a voice agent how your calls should go, then routing your phone line to it. You prepare call flows and FAQs, connect your calendar and CRM, route calls via forwarding, test with real calls, then go live and tune the script from recordings. Basic agents can be live in under an hour.
This guide is for owners and office managers at law firms, medical practices, financial firms and contractors who have decided to try an AI receptionist and want the setup to go right the first time.
Most of what ranks for this question is either a developer tutorial or a phone company pitch. Neither tells you what to decide before you start, or which calls to hand over first. Below you get the prep checklist, the setup steps in order and a realistic timeline. The rollout most owners use is overflow and after-hours calls first, then expand.
No code is involved. The real work is deciding how each call should end.
What do you need before you set up an AI receptionist?
You need your call flows written down, your calendar and CRM logins, and a decision on which calls go to the agent first. Gather these before you touch any settings. Brief the agent the way you would brief a new front desk hire.
| Item | What to have ready | Why it matters |
|---|---|---|
| Your business number | The number callers already use | Calls get routed to the agent behind it |
| Common caller questions | Hours, location, services, next steps | These become the agent's answers |
| Intake questions | What you must know before booking | Lets the agent qualify the caller |
| Routing rules | Which calls book, which go to staff, which leave details | Defines how each call ends |
| Calendar | Google Calendar, Calendly or similar | The agent books straight into it |
| CRM | HubSpot, Salesforce, Pipedrive or similar | Contacts and call details sync over |
| Alert recipients | Who gets the SMS and email for each call | Nobody misses a new lead |
The agent connects with HubSpot, Salesforce, Zendesk, Slack, Calendly, Zapier, Pipedrive, Google Calendar and n8n. If your tool is not on that list, ask on the demo how it would connect.
The setup steps, in order
Steps 1 to 5 are prep and wiring. Steps 6 and 7 get you live and improve the script.
- Choose which calls go first. Most owners start the basic agent on overflow and after-hours calls. Nobody answers those today, so you have little to lose and every answered call is a lead you would have missed.
- Map your call flows. Write down what callers ask and how each call should end. A booked consult, a booked estimate, a message for staff, or a polite redirect for calls you do not take.
- Write your intake questions. These are the facts you need before you book. A law firm agent asks for the other party's name so the firm can run a conflict check before booking. A financial firm might ask about the type of account. A contractor might ask about project scope and address.
- Connect your calendar and CRM. The agent books straight into your calendar with confirmations and reminders, and syncs call details to your CRM. See how AI appointment booking works for the mechanics.
- Set routing and alerts. Point the chosen calls at the agent. Call forwarding from your carrier is the usual method, so your published number stays the same. Then pick who gets the instant SMS and email alert for every call.
- Test with real calls. Call your own line and play the hard callers. A rushed caller, a confused caller, a caller outside your practice area. Confirm the booking lands in the calendar and the details land in the CRM.
- Go live, listen, then expand. Calls can be recorded and transcribed. Listen to the first batch, adjust the script, and only then hand the agent more of your call volume.
Step 7 is the one people skip. It is also where the script gets fixed.
How long does setup take?
A basic agent can be live in under an hour. A full setup usually takes about a week. The difference is scope. The basic agent answers and captures callers. The full setup covers your calendar, CRM, intake questions and call routing.
| Stage | Basic agent | Full setup |
|---|---|---|
| Time to live | Under an hour | About a week |
| Calls it covers | Overflow and after-hours, typically | Whatever you route to it |
| Intake questions | Core questions | Your full intake script |
| Calendar and CRM | Optional at first | Connected and syncing |
| Call routing | Simple | Your full routing rules |
Most of that week goes to your decisions about what the agent should say when a caller asks something unusual. Answer those faster and you go fully live faster.
Should you build your own AI receptionist or use a platform?
Build your own if you like tinkering and have time to maintain it. Use a platform if you want calls answered this week. Tutorials show agents built on Retell, n8n workflows, or a single Gemini API. Those builds work, but you own the prompts, the testing, the integrations and every fix when something breaks at night.
A managed platform hands you the voice agent, the calendar booking, the CRM sync and the alerts already wired together. You still write the script and the intake questions. Someone else maintains the connections.
Human answering services like Smith.ai and Ruby are a third option. They put a live person on your calls, which some firms prefer for complex or emotional callers. Our AI receptionist vs answering service comparison lays out the tradeoffs.
How much does it cost to run an AI receptionist?
Cost depends on how many calls you send to the agent and how much setup you need, so Target Dial quotes on a call. Compare it to the person you would otherwise hire.
The U.S. Bureau of Labor Statistics puts the median annual wage for receptionists and information clerks at $38,010, and the mean at $39,460, based on May 2025 data. That pays for one person on one shift, answering one call at a time.
An AI agent answers 24/7, handles up to 20 simultaneous calls, and speaks more than 20 languages. Hard cases still need your judgment. The Sunday night caller still gets an answer instead of voicemail. For the full math, read voice AI vs hiring a receptionist.
What is the 30% rule for AI, and does it apply to a phone agent?
The 30% rule is a rule of thumb. No standards body sets it. Customer support vendor Crisp tells teams to launch an AI agent as the default first responder and set expectations at 30% automated resolution rather than 80%. Crisp writes about chat support, and the number is their guidance, not a measured result.
The idea carries over to phones. Do not expect the agent to finish every call on day one. Give it a slice of calls you can afford to learn on, which is why overflow and after-hours come first. Count how many of those calls end the way you wanted. A booked consult, a captured lead, a clean message for staff. Fix what failed, then widen its share.
Set your own target from your own calls. A realistic target keeps you from pulling a working agent after one bad week.
Why start with after-hours and overflow calls?
Because those are the calls you are already losing. The Oklahoma Bar Association, summarizing Clio's 2024 Legal Trends Report, notes that only 40% of law firms answered a call from a prospective client, down from 56% in 2019. Of the firms that missed a call, only 20% returned it.
The same write-up reports that callers who reached a real person were more likely to recommend the firm, at a 39% recommendation rate. Email did no better as a fallback. The Institute for Law and Civility's summary of the same report says just 33% of firms responded to emails.
The first job is to answer the calls that ring out. For estate and probate firms, our after-hours intake protocol shows what those calls should capture, and the law firm answering service page shows how the agent handles them.
How do you tune the agent after launch?
You tune it from real calls. Calls can be recorded and transcribed, and every call triggers an SMS and email alert with a call breakdown showing who converts and who hangs up.
Read the hang-ups first. They tell you where the agent lost the caller. Then read the calls that did not book. Was a question missing from the FAQs? Did the intake run too long? Fix one thing at a time and listen again.
Once the overflow and after-hours calls sound right, expand. Route lunch hours next, then busy mornings. Most owners grow the agent's share of calls this way, after they have heard enough real calls to trust it.

Frequently asked questions
How do I create my own AI receptionist?+
You have two paths. You can build one yourself with a voice platform such as Retell, an automation tool like n8n, or a model API like Gemini. That works if you enjoy prompts, testing and upkeep. Or you can use a managed platform that handles the voice agent, calendar booking and integrations for you. Most firm owners pick the second path so they are not the ones maintaining prompts and fixing integrations.
How much does it cost to run an AI receptionist?+
Cost depends on call volume, how many calls you send to the agent, and how much setup you need. Target Dial quotes on a call because those inputs change the number. For a baseline, the Bureau of Labor Statistics puts the median annual wage for receptionists and information clerks at $38,010 as of May 2025. That covers one person on one shift.
How long does it take to set up an AI receptionist?+
With Target Dial, a basic agent can be live in under an hour. A full setup usually takes about a week. The full setup covers your calendar, CRM, intake questions and call routing. Most of that week goes to your decisions about how each call should end. The technology is rarely the slow part.
Do I have to change my business phone number?+
Usually not. The common method is call forwarding, a standard setting most phone carriers offer. Your published number stays on your website, your signage and your Google profile. You can forward only overflow and after-hours calls, or all calls. Ask on the demo how your specific phone line connects, since carriers and phone systems differ.
What happens to caller information, especially for law firms and medical practices?+
The agent captures what the caller says, books the appointment, and sends the details to your calendar and CRM. Calls can be recorded and transcribed, and you get an SMS and email alert for every call. If your practice has specific data handling requirements, ask us on the demo how we handle them.
