Usage Notes

  • Phone Number Configuration: The fromNumber must be configured in your project’s SIP trunking settings with:
    • Outbound SIP status set to ‘active’
  • Call Queue: Each toNumber can only have one active call in the queue at a time. If you attempt to create a call to a number that’s already queued, you’ll receive a 409 error.
  • Dynamic Variables: Use dynamicVariables to pass custom data to your call flow. These variables are available throughout the call session and can be used for personalization or call routing logic.
