I want to deploy an AI-driven voice and chat agent that can talk to our patients naturally, day or night, and take appointment management completely off the front desk. Patients should be able to phone in, open a web widget, or use our iOS/Android app and immediately: • schedule, reschedule, or cancel an appointment—this is the top priority • ask about available time slots, treatment options, or our clinic hours • receive automatic SMS / email reminders generated by the same system The agent must integrate cleanly with our clinic management software through its REST API so every action lands instantly in our calendar. A cloud-based solution built with Dialogflow CX, Rasa, Amazon Lex, or a comparable HIPAA-compliant stack is fine as long as it supports SIP/Twilio for phone calls and can embed in mobile and web channels. Round-the-clock uptime and smooth error handling are essential. Deliverables • Production-ready multichannel agent (phone, web chat, iOS/Android SDK) • Middleware that syncs appointment data with our system in real time • Automated reminder service tied to appointment events • Source code, configuration files, and deployment scripts in our Git repo • Quick video walkthrough and concise admin guide Acceptance Criteria 1. A live test call schedules an appointment that appears in our system within 10 s. 2. The FAQ module correctly answers at least 90 % of predefined questions on treatments, availability, and hours. 3. Reminders fire automatically at the configured intervals. 4. Load testing validates stability with 100 concurrent users. Tell me which tech stack you’d use, any libraries or services you prefer (e.g., Twilio Voice, Dialogflow, AWS Lambda), and how long you’ll need to hit these milestones. I’m ready to move forward right away.
