Twilio Voice routes phone calls to a deployed Agent Build. Provision a number, point the voice webhook to Phinite, then assign the build via Deploy to Channel for DEV / UAT / PROD.

​
Set up Twilio Voice

  1. Provision a Twilio phone number in your Twilio console.
  2. Open workspace Integrations → Channels → Twilio (or voice integration for your tenant).
  3. Enter Account SID, Auth Token, and related voice settings.
  4. Copy the DEV voice webhook URL from the saved Phinite configuration.
  5. In Twilio → Phone Numbers → your number → Voice Configuration, set the webhook URL to POST to Phinite’s DEV endpoint.
  6. Save your Conversational Agent Graph and create an Agent Build.
  7. Deploy → Deploy to Channel — select Twilio, assign build to DEV.
  8. Place a test call; review Observability logs and telephony metrics.
  9. Promote to UAT / PROD with matching webhook URLs per environment.

Design your Agent Graph for DTMF input and speech transcription if your flow collects keypad or spoken responses. Test latency in DEV before production traffic.
