  Practical guidance
</h2>

* For audio-heavy use cases, make the greeting early and concise. It is the caller's first signal that the call connected.
* Both media types follow the same answer policy and webhook flow.
* During design-partner rollout, `call.incoming` includes `media`, allowing different accept or decline logic by call type.
