AI Voice Assistant and call supporting

I need an end-to-end AI voice assistant that can immediately take over our incoming phone line, understand the caller’s intent, and answer questions on the spot. The first and most important ability is to handle inbound calls and general enquiries without human help; only when a question truly falls outside the knowledge base should it gracefully acknowledge the gap and still try to provide a complete answer rather than transferring or requesting a call-back.

Knowledge for responses must be pulled in real time from our CRM / support platform, so tight API integration there is essential. Beyond that core task, I also want the same assistant (or a companion chatbot) to:

• schedule and reschedule appointments,
• trigger outbound follow-ups, and
• sync all transcripts, notes and booking details back to the CRM.

Twilio (or a comparable telephony SDK) will provide the voice layer, while webhooks or REST endpoints can link the system to our website and calendar tools.

Deliverables
• A production-ready voice agent connected to Twilio that answers, converses and books appointments.
• A text chatbot counterpart using the same intent models.
• CRM integration for reading FAQ data and writing interaction logs.
• Deployment guide and source code in a private repo.
• Short video walkthrough showing the assistant fielding a live call.

Acceptance criteria
The assistant must correctly answer at least 90 % of a supplied test suite of common customer questions, complete bookings end-to-end, and log every interaction back to the CRM without errors.

If this aligns with your expertise in conversational AI, telephony, and API orchestration, I’m ready to get started right away.
