The PreAnswer element

The PreAnswer element answers an incoming call in early media mode. This is useful when you want to play custom caller tunes or to speak text while the call is still in an unanswered state.

Note: Not all phone numbers support this feature. Browser SDK doesn’t support early media (PreAnswer) as it’s not a part of the WebRTC specifications.


The PreAnswer element does not have any attributes.

Nesting rules

You can nest Speak, Play, and Wait elements within the PreAnswer element.
