interrupt
Direction: your server → Dial. Makes the agent speak immediately, out of turn — for example
when your own logic decides the agent should cut in rather than wait for the next
response_required. Unlike response, it
carries no response_id because it isn’t answering a request.
Schema
Example
Like a response, an interrupt can be streamed
across multiple frames (set content_complete on the last) and can end the call with end_call: true.
