Calls turned into booked appointments, automatically.
We build an AI appointment booking voice agent that answers calls, checks live calendar availability, books, reschedules, and cancels appointments, and confirms by text — so your front desk isn't glued to the phone. Built on Retell, VAPI, or Twilio and wired into Obsivara, you can see booking success rate, per-call cost, and any booking that failed to write to the calendar.
- Appointments booked 24/7 without staff on the phone
- No double-bookings — availability checked live
- Fewer no-shows from automatic confirmations
- Failed bookings and call cost surfaced in Obsivara
AI Appointment Booking Voice Agent, done for you.
Live availability & booking
Check real-time openings across your calendar or scheduling tool, offer slots that actually fit, and write the confirmed appointment back — no double-bookings.
Reschedules, cancellations & reminders
Handle changes over the phone, free the slot instantly on a cancellation, and send SMS or email confirmations and reminders to cut no-shows.
Intake & routing
Collect the details you need at booking — reason, service, insurance, or account info — and route to the right person, location, or resource.

Scope & build
On a short call we scope exactly what you need, then design and ship it around your stack, data, and guardrails — with a fixed plan and timeline before any work starts.
Connect to Obsivara
Every system we build is wired into Obsivara read-only from day one — via native n8n, SDK, OpenTelemetry, or webhook. No proxy in your request path, so it never adds latency or a failure point.
Monitor & improve
You get cost intelligence, health scoring, silent-failure alerts, and a weekly audit — and we keep it reliable and tune it as your usage grows, or hand it over entirely.
Built by us. Watched by Obsivara.
Because we build the AI observability platform these agents run on, monitoring isn't an afterthought — every voice agent ships connected to Obsivara via one read-only API key, with per-call cost attribution, latency and dropped-call detection, and health scoring live from day one. Nothing sits in your call path, so nothing we add can add lag to a live conversation.
AI Appointment Booking Voice Agent — common questions
Which calendars and scheduling tools does it work with?
It integrates with Google Calendar, Outlook, and common scheduling and practice-management tools on your own accounts. Obsivara confirms each booking wrote successfully, so a call that 'booked' but never hit the calendar is caught immediately.
How is calling billed?
The agent runs on your Retell/VAPI/Twilio and model accounts, so telephony minutes and model usage bill directly to you. Obsivara tracks cost per call and per booking so you always know what a booked appointment actually costs.
