Case study 01 · Voice AI

VeraVoice

An AI receptionist that answers every call on the first ring, books the appointment and screens out spam, on a voice pipeline we own instead of one we rent by the minute.

per minute. We own the voice pipeline, so there is no middleman.

01The situation

The most expensive callis the one nobody sees.

It comes at 7pm, or on a busy Saturday, or while the one person who answers phones is with a patient. It rings out. The caller doesn't leave a voicemail, because leaving a voicemail feels like effort and dialling the next result on Google doesn't.

Nobody records that loss. It shows up later as a quiet week.

For a small practice, both obvious fixes are bad. A night receptionist costs more than the calls are worth. A voice-AI platform charges per minute forever, on top of model and telephony costs, so the bill grows exactly as fast as the business does.

9:14 PM. The front desk is closed. The phone isn't.

02What we ruled out

Three ways to answer the phone, and why we didn't pick any of them.

✕

Hire an evening receptionist

Covers a few extra hours, not 24/7. Costs a salary to catch calls that arrive in bursts.

Cost scales with hours, not calls
✕

Rent a voice-AI platform

Fast to demo. Then every minute of every call carries a platform fee on top of the model and the phone line.

Per-minute tax, forever
✕

Voicemail + IVR menu

Cheapest option. Also the one callers hang up on. “Press 2 for appointments” is where bookings go to die.

Callers don't wait

So we built the voice pipeline ourselves. The clinic owns the agent. Nothing sits between the business and its own phone calls.

03Listen to a call

Vera · AIThank you for calling Lakeside Dental, this is Vera. How can I help you tonight?
CallerHi, yeah. I chipped a tooth at dinner. It doesn't hurt much, but I'd like someone to look at it soon.
Vera · AII'm sorry to hear that. I can get you in quickly. Are you an existing patient with us?
CallerNo, it's my first time.
Vera · AINo problem. Dr. Patel has openings tomorrow at ten thirty, or two p.m. Which works better for you?
CallerTwo o'clock is perfect.
Vera · AIGreat. Can I get your full name, please?
CallerSarah Mitchell.
Vera · AIThanks, Sarah. You're booked for tomorrow at two p.m. with Dr. Patel. I've just texted you a confirmation and a short new-patient form. Anything else I can help with?
CallerNo, that's great. Thank you so much!

04What we built

A receptionist,and the consolebehind her.

01Live console

Every call as it happens: the transcript, the slot Vera offers and books, and the spam she blocked.

02Clinic dashboard

Calls, after-hours answers, bookings and bot health at a glance. Shown with demo data.

03Spam screening

Robocalls flagged with a confidence score and blocked, so the front desk stops ignoring the phone.

04AI bookings

The week fills itself. Every appointment Vera made, next to the ones the front desk took.

05Under the hood

Owned,not rented.

Hover any block. The same agent runs on OpenAI Realtime and on Gemini Live, so “no vendor lock-in” is a config switch, not a slogan.

Vera core. Our own orchestration: persona, guardrails, spam classifier and tool calls. No per-minute platform in the middle.

Response time

Under three seconds round trip, the point where callers stop noticing they are talking to software.

What we own

The pipeline, the prompts, the classifier and the console. The client pays for models and telephony, not for a platform markup.

06The part nobody sees

Sounding humanis a set ofdials.

Accent, language, affective tone, proactive audio, how long the model may think, which classifier runs. In VeraVoice these are settings, not code.

That's the difference between sounding like a person and sounding like a phone tree, and it's why the same engine also runs our AI interviewer. Try them.

08How it ships
01

Discovery

We listen to real call patterns: when they peak, what people ask, what a booking needs.

02

Voice design

Persona, tone, language and guardrails tuned per business, then tested on scripted calls.

03

Integration

Calendar, SMS, CRM and the clinic's existing number. No new phone system.

04

Live + tuned

Calls monitored in the console. Misses become fixes within days, not quarters.
