Phone Numbers

Provision numbers and route calls.

Setup

  1. Add a number under Phone Numbers (via your Twilio account).
  2. Point the number's Voice webhook at the platform's inbound endpoint.
  3. Assign the number to a published voice agent in its Inbound Settings.

A Twilio local number runs ≈ $1.15/month, plus ≈ $0.0085/min for inbound voice and ≈ $0.0079/SMS — all passed through at cost.

Call routing

Inbound calls hit the Twilio webhook, which returns TwiML that streams the call to the voice server over a WebSocket. The agent answers; tools like transfer_call can hand off to a human or another number mid-call.
