AI Phone Agents Built on Vapi
Vapi provides the complete voice AI stack — speech recognition, AI reasoning, voice synthesis, and phone call infrastructure — so we can focus on building your AI agent, not managing telephony.
How we use Vapi
Vapi is an infrastructure platform for AI phone agents. It handles the complete technical stack: inbound and outbound calls via phone numbers, real-time speech-to-text, LLM integration for reasoning, text-to-speech with multiple voice providers (ElevenLabs, Deepgram), and calendar/CRM integrations. We build on Vapi because it solves the hard telephony and streaming problems — leaving us to focus on the agent design, business logic, and integrations that actually differentiate your system.
What this means for your project
- ✦Production-ready Vapi integrations, not demos
- ✦Code you own — no black boxes
- ✦Engineers who have shipped real systems with this stack
- ✦Ongoing support and updates after launch
What we build with Vapi
Inbound call handling
Answer every call on the first ring, qualify the caller, answer questions from your knowledge base, and book appointments — automatically, 24/7.
Outbound lead follow-up
Call new leads within 60 seconds of form submission, qualify them, and book discovery calls — before they sign up with a competitor.
Appointment reminders
Automated outbound calls to remind patients, clients, or customers about upcoming appointments — with natural conversation for rescheduling if needed.
After-hours coverage
Handle everything your receptionist would during business hours — bookings, emergencies, enquiries — at 2am on a Sunday.
Common questions
Does Vapi work for non-US phone numbers?+
Yes — Vapi supports UK, Australian, Canadian, and dozens of other country numbers. International deployments require language configuration and sometimes local voice provider adjustments.
Can the AI agent transfer calls to a human?+
Yes — call transfer to a human is a standard feature. You define the conditions: emergency keywords, request for a human, or specific enquiry types trigger a warm transfer to your team.
