RTCPeerConnection.defaultIceServers

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The read-only property RTCPeerConnection.defaultIceServers returns an array of objects based on the RTCIceServer dictionary, which indicates what—if any—ICE servers the browser will use by default if none are provided to the RTCPeerConnection in its RTCConfiguration. However, browsers are not required to provide any default ICE servers at all.

Syntax

 var defaultIceServers = RTCPeerConnection.defaultIceServers;

Value

An array of ICE servers, specified as objects based on RTCIceServer,  which the browser will use if none are specified in the configuration of the RTCPeerConnection. If there are no defaults provided by the browser, the returned array is empty; this property's value is never null.

Example

var pc = new RTCPeerConnection();
var iceServers = pc.defaultIceServers;

if (iceServers.length === 0) {
  // Deal with the lack of default ICE servers, possibly by using our own defaults
}
