The phone & chat agent that never misses a lead

A 24/7 AI agent that answers overflow and after-hours phone calls — and website chats — quotes from the real price list, and books, cancels or reschedules against the same system my staff use.

The problem: Every missed call after hours or during a rush is a booked job walking to a competitor.
The old way: Voicemail nobody returns fast enough, or an answering service that can't quote or book.
The AI way: A natural-voice agent greets the caller, captures the lead, quotes through our real pricing engine, recognizes callers with an upcoming appointment, and reschedules or cancels against the same scheduler the humans use.
The impact: About 17% of calls are pure voicemail and ~45% are actionable leads — now captured 24/7 instead of lost. Quotes come from the real price list, not a script.
The honest edge: Spanish callers are greeted and captured for a callback, not fully handled — a deliberate v1 boundary. I tell you where it stops, not just where it shines.

Build your own

Everything below is how it was actually built — the real journey, the prompts, and a starter repo you can run.

Build journey & gotchas

“The voice transport is settled.” — the opening line of the plan the next six weeks demolished.
A digit-spacing rule meant for ZIP codes once spoke a $4,000 quote out loud as “four hundred to five hundred.”
A location-prefix shortcut told a caller 170 miles away they were inside the metro service area.

Prompt pack

The real system prompts, tool definitions and guardrails that run the agent — sanitized and ready to adapt.

Runnable starter repo

Clone it, add your keys, and have a working voice-agent skeleton answering calls in an afternoon.

Architecture + ROI model

How the pieces fit end to end, and what it actually costs per call at your volume.
