Echo audio back to the caller. This is primarily useful for testing audio quality, latency, and connectivity. The caller hears their own voice repeated back to them.

This method emits calling.call.echo events. See Call Events for payload details.

Parameters

Maximum duration of the echo in seconds. The echo stops automatically after this timeout.

status_url

Optional[str]

URL to receive echo status webhooks.

Returns

dict — Server response confirming the echo operation.
