Web/API/RTCOfferOptions

The RTCOfferOptions dictionary is used to provide optional settings when creating an RTCPeerConnection offer with the createOffer() method.

Properties

This dictionary also inherits properties from the RTCOfferAnswerOptions dictionary, on which it's based.

iceRestart Optional

A Boolean which, when set to true, tells createOffer() to generate and use new values for the identifying properties of the SDP it creates, resulting in a request that triggers renegotiation of the ICE connection. This is useful if network conditions have changed in a way that make the current configuration untenable or impractical, for instance.
