A realistic use case with concrete timing and output.
Scenario: A 3-truck HVAC company misses roughly 15 calls a week while techs are on jobs or after hours. The agent texts back every one within 10 seconds: "Hi, this is [Company] — sorry we missed your call! What's going on with your system, and would you like to grab a slot here: [link]?" Of those 15, about 6 reply and 4 end up booked directly through the text thread.

Common questions about using the AI agent in workflows.
The core fix is speed: text the caller back within seconds of the missed call, before they've had a chance to call the next number on their list. This agent automates that instant reply and carries the conversation through to a booked appointment, so the fix doesn't depend on someone in the office noticing the missed call first.
It depends on whether you want a fixed point solution or something you can shape to your own business. This agent is a custom build: you control the exact wording, booking flow, and what it connects to, rather than renting a generic tool. It's built on Twilio, so it works with the phone number and calendar you already use.
Yes. The agent connects to your existing line through Twilio's call-forwarding or SIP integration, so you keep the same number customers already call. No new number for customers to learn.
The agent holds a real back-and-forth conversation — answering basic questions about availability, pricing ranges, or service area — and steers toward booking once the caller is ready. Anything it can't confidently answer gets flagged for a human to follow up.
Yes, as an optional step. Once an appointment is confirmed, the agent can create the job directly in Jobber or Housecall Pro via their API so dispatch doesn't have to re-enter anything by hand.
Yes, by default it runs 24/7 with the same response time as during business hours. You can add rules to flag true emergencies for a human on-call tech rather than letting the agent handle triage on its own.
Yes. Point the agent at a test phone number first, run through a few missed-call scenarios, and confirm the wording, booking flow, and CRM logging all match how you run the business before switching over your live line.
