Request Syllabus / Call BackProgram Overview
A voice agent that is nearly good enough is worse than none — customers forgive a chatbot and never forgive a phone system. Two days are built around that. You work Retell and Vapi to build a phone agent that handles a real call, then ElevenLabs for a voice that does not make people hang up. Day one covers the things voice makes hard and text does not: interruption, latency, background noise, and someone talking over your agent. Day two is the work — calls, FAQs and bookings handled around the clock — then CRM and ticketing integration through n8n, and the escalation path, which for voice must be immediate and graceful. You leave with a live agent and honest numbers on what it handled.
