What it is: Aria, a 24/7 AI voice receptionist (Retell + n8n + GHL stack) built for a potential Medical Spa client, handling real calls across multiple services and practitioners. Aria currently handles 9 capabilities: Check Availability, Book an Appointment, Rescheduling an Appointment, Cancellation of an Appointment, Sending Booking Link, Leave a Message (voicemail-style), Human Handover (notifies the team for an immediate callback), Upsell Inquiry, and FAQs. In the attached demo call, you'll see the booking lifecycle live - check availability, book, reschedule, cancel in one continuous conversation, no resets between intents. There's also a separate flow for consultation bookings, with its own check-availability/book/reschedule/cancel logic, handled independently from treatment appointments. Backend-wise: each service auto-routes to the correct practitioner's calendar, CRM contacts and pipeline opportunities update in real time, and GHL workflows fire SMS/email confirmations plus internal staff alerts, all hands-off. https://www.loom.com/share/958d1a87d9c548c8a37035e5d80ee49e Video + screenshots of the calendar, opportunity pipeline, and the n8n logic attached below. Happy to talk through the routing/calendar-conflict logic if anyone's tackling something similar. Thank you Ashton for the fundaments!😃
