A phone line that answers, and talks back.

An AI call centre built on Twilio and the OpenAI Realtime API, holding the conversation in voice.

Anything out of scope

The problem

First-line phone handling was eating staff time. People broke off their own work for routine confirmations and transfers.

What we did

  1. 01

    Connected to the phone network through Twilio, with the OpenAI Realtime API handling speech directly

  2. 02

    Skipped the transcribe-generate-speak round trip to close the gap between turns

  3. 03

    Drew a clear line for handing anything beyond scope to a person

  4. 04

    Collected real calls and tuned the range it can cover

The result

AI takes the first line, and only the calls that genuinely need a person reach one.
