From idea to answered calls in under an hour
Two years ago, deploying an AI voice system meant hiring developers, buying telephony hardware, and waiting weeks for setup. Today, you can have a working AI agent answering your business calls before lunch.
This guide walks through the exact process for setting up VibeVoice — not in theory, but step by step, in the order you'll actually do it. If you follow along, you'll have a live AI receptionist by the time you finish reading.
Before you start: what you'll need
You need three things: a phone number for your business (the one callers already use), access to your calendar system (Google Calendar, Microsoft Outlook, or your booking software), and about fifteen minutes.
You do not need to write code, manage servers, or understand how large language models work. The configuration happens through a visual dashboard. Technical decisions are handled for you.
Step 1: Connect your phone number
The first decision is how incoming calls reach VibeVoice. There are two approaches:
Call forwarding. You keep your existing phone number and configure your carrier to forward calls to VibeVoice when the line is busy, unanswered after a set number of rings, or at all times. This is the most common setup and takes about three minutes with your carrier's phone or online portal. Most carriers support conditional forwarding codes — your VibeVoice dashboard will give you the exact code to dial.
Number porting or a new number. If you want VibeVoice to be the primary answering point for a new business number, you can port an existing number or provision a new one directly through the platform. This is useful for businesses setting up a new line specifically for a reception or enquiry function.
For most businesses starting out, conditional forwarding on busy and no-answer is the right choice. Callers who reach a free human get through normally; callers who would otherwise reach voicemail go to VibeVoice instead.
Once forwarding is active, call your own number from a mobile. You'll hear the VibeVoice greeting rather than voicemail — that confirms the connection is working.
Step 2: Choose your voice and language
VibeVoice offers multiple voice profiles for Dutch, English, German, and French, with additional languages in preview. Each voice has been tested for clarity and naturalness across a range of call types.
For most European service businesses, the practical choice comes down to:
- Language: Match your primary caller base. For a Dutch GP practice, Dutch is the default; for a law firm that handles both Dutch and international clients, you might configure Dutch as primary and English as a secondary option, with the agent asking callers to state their preference.
- Voice character: VibeVoice offers both warmer, more conversational voices and more formal, professional ones. A dental practice might prefer a warm and reassuring tone; a law office might prefer measured and precise. Listen to the samples in the dashboard and choose the one that fits your brand.
- Speaking pace: The default pace works well for most situations. If your callers tend to be older or less familiar with automated systems, a slightly slower pace reduces friction.
Once selected, you can run a test call from within the dashboard to hear exactly how your agent sounds before it handles real calls.
Step 3: Define your call flows
This is where you tell the agent what to do. VibeVoice uses a visual flow builder — no scripting language, no programming. You're connecting logical blocks: what the agent says, what it listens for, what it does next.
A typical starting configuration for a service business might look like:
Greeting block. What does the agent say when it picks up? "You've reached [Business Name]. I'm the digital assistant — I can help with appointments, opening hours, and general questions. How can I help you today?"
Intent recognition. The agent categorises what the caller says into a set of intents you define. For a physiotherapy practice, common intents might include: book appointment, cancel or reschedule, question about a specific treatment, billing question, emergency or urgent matter, speak to a person.
Action blocks. Each intent routes to an action. Book appointment → calendar integration, showing available slots and confirming a booking. Cancel → lookup and cancellation flow. Emergency → immediate handoff to a mobile number or emergency line. Speak to a person → transfer to your front desk (or, outside of hours, take a message).
Out-of-hours behaviour. You set your opening hours and what happens when someone calls outside them. The agent can inform callers of your hours, take a message with a callback request, or book appointments for future slots depending on the caller's need.
Spend time here. The quality of your call flows is what determines whether callers leave the interaction satisfied. VibeVoice includes templates for common business types — dental practice, legal office, salon, property agency — so you're not building from scratch.
Step 4: Test before you go live
Before activating the agent for real callers, run your own tests. VibeVoice has a built-in test mode where you can call in from a designated number and simulate real interactions without those calls appearing in your live dashboard.
Test every flow you configured:
- Call and ask to book an appointment. Does the agent find the right calendar slots? Does the confirmation come through?
- Call and ask a question the agent can answer (your address, your opening hours, your prices if you've configured them). Does it give the right information?
- Call and ask something the agent can't handle. Does it escalate gracefully?
- Call outside of hours. Does the out-of-hours message match what you configured?
- Call and immediately say "I want to speak to a human." Does handoff work?
Fix any flow gaps before going live. A caller who gets a confused or looping response will have a worse experience than if they'd reached voicemail.
Step 5: Monitor and optimise
Your work is not done when the agent is live — it is just beginning.
In the first week, check your VibeVoice dashboard daily. You'll see a log of every call: what the caller said, how the agent responded, what action was taken, and the outcome. Look for patterns:
Calls that escalated to a human unexpectedly. What did those callers say? Were there phrases or questions the agent should have handled but didn't? Add those to your flows.
Calls with short duration before hang-up. Some of these are misdials, but others suggest the agent's greeting or initial response wasn't clear. Refine the opening.
Appointment bookings. Are they being completed successfully? Check a sample against your calendar to confirm that booked appointments are appearing correctly.
Caller satisfaction. After 30 days, review your Google reviews and direct feedback. Do any mention the phone system? Listen to a sample of your transcripts. Would you be happy if that were your experience calling a business?
Most businesses make two or three refinements in the first month — adjusting how flows are worded, adding missing intents, updating information that changed. After that, the system typically runs stably for months at a time.
Tips from businesses that have done this before
Don't hide that it's AI. Businesses that are upfront about their digital assistant ("Hi, I'm the VibeVoice assistant for [Business Name]") consistently report higher caller satisfaction than those who try to sound entirely human and then fail to answer an unusual question. Transparency builds trust.
Start narrow. Your first version doesn't need to handle everything. Set up the three or four most common call types first. Go live. Then expand based on what you observe in the logs.
Update seasonally. If your business has different hours in summer, holiday periods, or during promotions, update the agent's information before those periods start. Stale information is one of the most common complaints about automated systems.
Use the callback flow. For callers who catch you at a moment when the agent can't help, a well-handled message-taking flow ("I'll make sure someone from the team calls you back within two hours") often produces better satisfaction than a simple escalation to voicemail.
What happens after setup
The businesses that get the most from VibeVoice are the ones that treat it as a live operational tool, not a set-and-forget installation. Thirty minutes a month reviewing your dashboard data, adjusting flows, and updating information is enough to keep the system performing well.
After the first 90 days, most customers report one consistent observation: they no longer think about missed calls. The gap between inbound interest and captured leads has closed. The phone is no longer a source of anxiety for reception teams — it is simply handled.
That is what a working AI voice agent produces. Not magic, but reliable, measurable capture of every caller who reaches out to your business.
