How to stop all connections

[VGubarev]

Hi, guys! I've got a problem. WebRTC.io have API for create connections, but how i can stop all connections and go out from room without restart page?
I have tried do this:
[js]
rtc.closeStreams = function() {
rtc.fire('disconnect stream', rtc._me);
for (id in rtc.peerConnections) {
if (typeof(rtc.peerConnections[id]) !== 'undefined') {
rtc.peerConnections[id].close();
}
delete rtc.peerConnections[id];
delete rtc.dataChannels[id];
delete rtc.connections[id];
}
};
[/js]
Yea, it closes all inner streams and stop camera, but server didn't sends to all other participants of room "remove peer connection".

How i can close all streams and alert clients that one of them go out from room ( without page restart)?
