Flush queued playback
{"event":"clear","stream_sid":"..."}
When the caller interrupts, stop generation and flush the carrier's queued audio. Doing only the first half still talks over the caller.
Your responsibility
You own the Exotel account, line, flow, registration obligations, and Exotel charges.
Point the Voicebot applet in your Exotel flow at your bridge endpoint.
Implement and secure the media gateway you control. From your trusted server, create
/v2/voice/sessions with a project key, then connect only to the returned one-use stream URL.Official references · 13 September 2026
Verify the current stream contract
Protocol references are official starting points, not proof that an account is enabled. Confirm the current carrier contract and account capabilities before implementation.

Use the current Voicebot and streaming documentation available for your account.
Machine handoff available
Create /v2/voice/sessions from a trusted server with X-Api-Key. The response returns a short-lived, one-use stream URL; never put the project key in browser code or adapt an earlier account-wide request.
