Incoming Phone Numbers

Incoming call status callback

Payload sent by SignalWire to your Inbound Call Status Callback URL for inbound calls to a phone number.

Configure StatusCallback at the phone number level via the dashboard (Phone Numbers → select a number → Phone Number Settings) or programmatically via the create or update Incoming Phone Number API endpoints.

By default, the webhook fires only when the call is completed or failed, making it well-suited for tracking inbound call success rate, call quality, and total call volume in a call center context.
