Bandwidth Voice API

The Bandwidth Voice API enables developers to programmatically make and receive phone calls, manage call recordings, and create multi-party conferences. It supports advanced call control features including call transfers, bridging, DTMF detection, and text-to-speech. The API uses BXML (Bandwidth XML) verbs for call flow control and provides webhooks for real-time event notifications on call state changes.
