Build an AI Receptionist with Dialzara (Step-by-Step)
Build an AI Receptionist with Dialzara (Step-by-Step)
A step-by-step workshop to set up an AI receptionist using Dialzara, so your business phone gets answered, appointments get booked, and no call goes to voicemail again. Follow along and build it while you read.
The call that went to voicemail, and what we're building
It's 1 PM. You're mid-appointment with a client. Your phone rings. You can't pick up. It goes to voicemail.
The caller doesn't leave a message. They call the next clinic, salon, or repair service on their list instead. Most callers who reach voicemail simply hang up rather than leave one. You didn't lose that customer to a competitor who's better than you, you lost them to whoever answered the phone first.
By the end of this workshop, you'll have an AI receptionist, built on a platform called Dialzara, that answers every call, day or night, answers common questions, books appointments directly into your calendar, and knows exactly when to pass a caller to you instead of guessing.
Before:
Customer calls → No answer / voicemail → Customer calls someone else
After:
Customer calls → AI receptionist answers → Books appointment or captures details → You handle anything it can't
What it will do:
Answer every call instantly, answer common questions about hours/pricing/services, check your calendar and book real appointments, and capture caller details when a human follow-up is needed.
What it won't do:
Invent information you haven't given it, promise availability it hasn't actually checked, handle a genuine complaint or emergency, or replace you for anything requiring real judgment.
What you need, and why Dialzara
Here's everything required, plus real, verified numbers, not estimates.
What you need | Cost |
|---|---|
A Dialzara account | Free to start, 7-day free trial |
Dialzara subscription (after trial) | Starts at $29/month, Business Lite plan, 60 receptionist minutes included, $0.48 per overage minute |
A phone number to forward from your existing line | Usually free, this is just call forwarding on your current number |
Google Calendar or Outlook, if you want live appointment booking | Free |
20-30 minutes to prepare your business information | Free |
Why Dialzara specifically:
It has one of the fastest, simplest self-serve setups in this category, a genuine four-step process most businesses complete in about 15 minutes, no developer, no long-term contract, no setup fee. It also natively syncs with Google Calendar and Outlook for real appointment booking, and records and transcribes every call so nothing gets lost.
One honest limit worth knowing upfront:
Dialzara uses a fixed prompt, meaning it responds the same way on call 1 as it does on call 1,000. It doesn't learn or improve on its own between calls, if callers keep tripping it up on the same question, you'll need to go back and manually update the instructions, which is exactly what Step 4 below teaches you to do.
Step 1: Prepare your business info, then write the AI's instructions
Part A: Prepare your business information
Why it matters: the AI can only answer correctly if you give it correct, complete information first.
Copy this:
Business name:
Business type:
Location/address:
Opening hours (all 7 days):
Services offered:
Prices (or price ranges, if they vary):
Frequently asked questions (list at least 5-10):
Appointment/booking process:
How far in advance can someone book:
Payment methods accepted:
Contact info for urgent matters:
Important policies (cancellation, late arrival, etc.):
Part B: Write the AI's core instructions
Dialzara will ask you a series of questions during setup and auto-generate a starting prompt from your answers, but having your own written instructions ready means you can paste in something far more specific than the defaults, and you'll need this exact text again in Step 5 when we fine-tune it.
Copy this:
You are the phone receptionist for [Business Name], a [business type] located in [location].
Your job is to answer calls professionally and helpfully, using ONLY the information provided below. Never invent prices, availability, or details that aren't listed here.
BUSINESS INFORMATION:
[Paste your completed business info template from Part A here]
HOW TO RESPOND:
Speak naturally and warmly, like a real receptionist, not a robotic phone menu.
If you don't know the answer, say so honestly and offer to have someone call back.
If a caller wants to book an appointment, check availability and confirm a real slot, don't guess.
If a caller has a complaint, an emergency, or asks for a person, immediately say you're connecting them or taking a message for an urgent callback, do not try to resolve it yourself.
Never promise discounts, exact availability, or anything not explicitly listed above.
Your results
A complete business info sheet and a ready instruction block, exactly what Dialzara's setup will ask you for.
Step 2: Build your FAQ brain, then see it in action
Part A: Build your FAQ brain
Copy this pattern
List your own top 8-10 questions the same way:
Q: What are your hours?
A: We're open Monday to Saturday, 10 AM to 7 PM, and closed Sundays.
Q: How much does [service] cost?
A: [Service] starts at $[price], the exact cost depends on [what it depends on].
Q: Do I need an appointment or can I walk in?
A: [Your actual policy here]
Q: How do I get to you?
A: We're at [address], [nearby landmark if useful].
Part B: See how real calls should flow
Asking about hours
Caller: "Are you open right now?"
AI: "Yes, we're open until 7 PM today. Is there something I can help you with?"
Asking about pricing
Caller: "How much for a consultation?"
AI: "A consultation is ₹500. Would you like me to check available slots for you?"
Booking an appointment
Caller: "Can I book for tomorrow afternoon?"
AI: "Let me check... yes, I have a 3 PM slot available tomorrow. Can I get your name to confirm that booking?"
Asking something outside what it knows
Caller: "Do you accept my specific insurance provider?"
AI: "That's a great question, let me take your number and have our team confirm that for you shortly."
An urgent or sensitive call
Caller: "I need to speak to someone right now, this is urgent."
AI: "Of course, let me take your details and get someone to call you back immediately."
Your result:
Your FAQ list ready to add into Dialzara, and a clear picture of what a well-handled call sounds like.
Step 3: Write your booking rules and human handoff rules
Part A: Appointment booking rules
Copy this
Adjusting to match your actual booking rules:
When a caller wants to book an appointment:
Check the connected calendar for real availability, never say a slot is free without checking.
Offer 2-3 real available times.
Once the caller picks one, confirm their name and phone number, then book it.
Read back the confirmed date and time before ending the call.
Part B: Human handoff rules
Copy this:
Immediately offer to connect the caller to a human, or take their details for an urgent callback, if the caller:
Has a complaint or sounds upset
Describes an emergency or urgent situation
Explicitly asks to speak to a real person
Has a request outside the information you've been given
Is trying to finalize a large or unusual booking
Never try to resolve these situations yourself, and never leave the caller with no next step.
Your result:
Two more ready blocks of instructions, all four pieces from Steps 1-3 (business info, core instructions, FAQ, booking/handoff rules) are now ready to go into Dialzara in the next step.
Step 4: Configure Dialzara, the actual setup
This is the real four-step setup, verified against Dialzara's own process. Most businesses complete this in about 15 minutes.
Create your account and start the free trial.
Go to Dialzara's website and sign up. You get 7 days free, no credit card risk of surprise charges, no setup fee.
Pick a voice and get your phone number.
Dialzara offers 50+ voice options and supports 10+ languages, listen to a few before choosing one that fits how you want your business to sound. You'll also get a Dialzara phone number at this step.
Upload your business info and customize your prompt.
Dialzara will ask you guided questions and auto-generate a starting prompt. Instead of relying only on the defaults, paste in your prepared content from Steps 1-3: your business info, your core instructions, your FAQ list, and your booking/handoff rules. Dialzara also offers 88+ pre-built industry prompt templates, worth checking if one matches your business type as a starting point.
Set up call forwarding.
This connects your real phone number to your new AI receptionist. You have two options: conditional forwarding (Dialzara only picks up when you don't answer, your line is busy, or your phone is off) or forward all calls (every call goes straight to Dialzara first). Most businesses starting out prefer conditional forwarding, since it keeps you as the first point of contact when you're free.
Optional, once the basics work:
Connect Google Calendar or Outlook so the AI checks and books real appointment slots instead of just taking messages. You can also connect Dialzara to over 5,000 other apps through Zapier, useful later for things like automatically texting a caller after their call, or updating a CRM, but skip this until the core setup is working well.
Your result:
A live AI receptionist, answering on your forwarded number, using the exact instructions you wrote.
Step 5: Test it properly, then fix what's broken
Part A: Test it
Call your own number and run through this exact checklist:
What are your hours?
Should give your real hours
How much does [main service] cost?
Should quote your real price
Can I book an appointment for [a real day/time]?
Should check calendar and offer real slots
I need to speak to a person
Should hand off immediately
Ask about something you don't actually offer
Should say it doesn't know, not guess
I have a complaint
Should hand off immediately, not try to resolve it
This is an emergency
Should hand off immediately
Can I get a discount?
Should not invent one
A completely unrelated question
Should politely redirect
Book a slot, then call back and ask to confirm it
Should correctly reference the real booking
Part B: Fix what's broken
Remember, Dialzara uses a fixed prompt, so it won't self-correct, if something's wrong, you fix the instructions directly.
AI invents availability instead of checking the calendar
Booking instruction wasn't explicit enough.
Add: "Never state a time is available without actually checking the calendar first."
AI sounds robotic or overly formal
No tone guidance given
Add: "Speak the way a friendly human receptionist would, in short natural sentences."
AI doesn't hand off an urgent call
Handoff rule missed a trigger phrase.
Add the exact words you noticed it missing, e.g., "emergency," "right now," "urgent."
AI books a slot without confirming caller details
Booking instruction skipped a required step
Add: "Never finalize a booking without confirming the caller's name and number."
Your result:
A tested receptionist with the specific fixes applied for your business, edited directly in your Dialzara prompt.
Real business examples, and what the AI should never do
Clinic:
Patients call during appointments when staff can't answer. The AI answers, explains the consultation process, checks calendar availability, and books a real slot. Result: fewer missed calls, front desk deals with confirmed patients instead of chasing missed enquiries.
Salon:
Calls come in constantly during busy hours when stylists are with clients. The AI answers instantly, quotes standard pricing, and books available slots directly. Result: no more "sorry, we were with a client" voicemail pile-up.
Home-service business (repair, cleaning, etc.):
Calls come in from job sites or after hours. The AI confirms service area and general pricing, and captures the issue and location as a lead for a precise quote. Result: no after-hours call goes unanswered, even when the final quote still needs a human.
(These are illustrative workflows based on how Dialzara is designed to work, not measured results from a specific client, since real outcomes will vary by business.)
What the AI should never do
Don't let it invent availability without checking the real calendar
Don't let it promise pricing or discounts you haven't confirmed
Don't let it handle a genuine emergency or complaint on its own
Don't give it access to sensitive information it doesn't need
Don't let it finalize a booking without confirming who the caller actually is
What you've built, troubleshooting, cost, and FAQs
What you've built:
Before, calls during busy hours or after closing went to voicemail, and most of those callers simply moved on. Now, every call gets answered instantly, common questions get handled correctly, real appointments get booked into your actual calendar, and anything sensitive gets passed straight to you.
Troubleshooting:
AI gives incorrect answers
Business info was incomplete
Go back and add more detail to your prompt.
AI sounds unnatural or overly scripted
No tone guidance given.
Add an explicit tone instruction, as shown in Step 5.
Bookings don't sync to your real calendar
Calendar connection wasn't completed.
Recheck the Google Calendar/Outlook integration from Step 4.
AI doesn't hand off urgent calls
Handoff rules missed specific trigger words.
Add the exact phrases you noticed it missing.
Same mistake keeps happening across calls
Remember, Dialzara doesn't self-learn, you have to manually edit the prompt each time, this is expected, not a bug.
Cost, verified:
Dialzara starts at $29/month (Business Lite plan), including 60 receptionist minutes, with a $0.48 per-minute overage rate beyond that. No setup fee, no long-term contract, and a 7-day free trial to test everything in this workshop before paying anything. Higher tiers (around $199/month) add "white glove" prompt engineering, where Dialzara's team helps refine your instructions for you.
(Pricing verified from Dialzara's own published rates as of this article's publish date. Confirm current pricing on their site before signing up, as plans can change.)
FAQs:
Do I need coding knowledge?
No, Dialzara's setup is entirely self-serve and guided, no code required.
How long does setup actually take?
About 15 minutes for the core four-step setup described in Step 4, most of the real work is preparing your content in Steps 1-3, which you've already done.
Can it actually check my real calendar?
Yes, Dialzara natively syncs with Google Calendar and Outlook.
Will callers know they're talking to an AI?
With 50+ voice options, most sound quite natural, listen to a few during setup and pick one that fits your business.
What happens if the AI can't answer something?
If you've followed the handoff instructions in this workshop, it takes the caller's details and passes them to you rather than guessing.
Can I use my existing business number?
Yes, Dialzara works by forwarding calls from your existing number, you don't need a new one for customers to call.
Does every transferred or after-hours call cost extra?
Dialzara's pricing is based on total receptionist minutes used per month (60 included on the Business Lite plan, then $0.48/minute), not billed per individual call or transfer.
Where to go from here
You now have everything needed to stop losing customers to missed calls, real instructions, a real FAQ brain, and a verified setup process, not just an idea of how one might work.
Start your 7-day free trial, run through the 10 test calls from Step 5 yourself, and give it a week of real calls before judging it. You'll likely find a few responses worth adjusting, that's normal, not a sign something's broken.
If you'd rather have this set up and refined for you, or connected into a broader system alongside your WhatsApp assistant and website, let's talk.
