{{APIRef("WebRTC")}}
The remoteDescription read-only property of the {{domxref("RTCPeerConnection")}} interface returns a {{domxref("RTCSessionDescription")}} describing the session (which includes configuration and media information) for the remote end of the connection.
If this hasn't been set yet, this is null.
The returned value typically reflects a remote description which has been received over the signaling server (as either an offer or an answer) and then put into effect by your code calling {{domxref("RTCPeerConnection.setRemoteDescription()")}} in response.
On a more fundamental level, the returned value is the value of {{domxref("RTCPeerConnection.pendingRemoteDescription")}} if that property isn't
null;
otherwise, the value of {{domxref("RTCPeerConnection.currentRemoteDescription")}} is returned.
See Pending and current descriptions in the WebRTC Connectivity page for details on this algorithm and why it's used.
This example looks at the remoteDescription and displays an alert containing the {{domxref("RTCSessionDescription")}} object's type and sdp fields.
const pc = new RTCPeerConnection();
// …
const sd = pc.remoteDescription;
if (sd) {
alert(`Remote session: type='${sd.type}'; sdp description='${sd.sdp}'`);
} else {
alert("No remote session yet.");
}
