Voice & IVR
Build interactive voice experiences — click-to-call, IVR menus, voice surveys, PIN delivery, call recording, machine detection, and inbound call handling.
Voice Conversations API lets you define dialplans (sequences of verbs like SAY, COLLECT, DIAL, PLAY) that control call flow programmatically. These tutorials walk through common patterns end to end.
Topics covered
- Call masking — anonymous two-party calls through a virtual number
- Click-to-call — connect two parties via an API-initiated call
- IVR flows — menu-driven voice interactions with DTMF input
- Voice surveys — collect responses over the phone
- PIN delivery — send and verify one-time codes via voice
- Call recording — record bridged conversations
- Machine detection — distinguish human answers from voicemail
- Inbound calls — receive and redirect incoming voice traffic
