AI Front Desk — Missed Calls, After Hours and Booking

Every missed call is a lead that was already paid for, and the caller reaches the next result in under a minute.

A service business misses a large share of inbound calls while staff are on a job, at lunch or gone for the day. An answering service costs by the minute, cannot see the calendar and books nothing.

The gates, 10 If and Switch nodes, decide whether anything happens next: a countable part of the system, not a claim about it. The 12 sticky notes carry the reasoning on the canvas, at the point it applies.

• The agent is the overflow, never the front door

  The agent is the overflow, never the front door

  Twilio reaches the workflow only as the dial action URL, after the human line has finished ringing; a call a person answered exits at once.

• Hours travel as a boolean

  Hours travel as a boolean

  A model that can reason about the time can reason its way into a Sunday appointment. Out of hours it still answers, with a link.

• A price from the table, or none

  A price from the table, or none

  A prompt saying “do not quote prices you are unsure of” is a request; a lookup that returns a refusal is a control.

• Six triggers, every turn, fixed words

  Six triggers, every turn, fixed words

  Matched against the running transcript, not left to the model to notice — and answered with fixed wording, because a gas call is the worst moment to improvise a handoff.

• Four confirmations, then a re-check

  Four confirmations, then a re-check

  Without the gate the agent books on “yeah, maybe Tuesday”. The slot was free when offered; two minutes later it may not be.

• If it was not said, it stays empty

  If it was not said, it stays empty

  The summariser writes only what is in the transcript. An address guessed from an area code looks exactly as confident as one the caller gave.

• Built, not yet deployed. The five workflows import clean and every connection resolves; no real call has flowed through them end to end.
• The voice agent itself — its prompt, voice and turn-taking — is configured in the vendor’s console. These workflows are everything around it: the routing, the tools and the write-back.
• The field-service CRM is Housecall Pro. Jobber or ServiceTitan means rewriting the booking workflow, and the slot builder assumes one shared calendar.
• There is no call-recording consent announcement yet. Two-party-consent jurisdictions need one before it goes live.
