--- Comment #42 from Tim Panton <tim at pi.pe> ---
We haven't had this problem in rendezvous.family or rendezvous.zone - But we have ptime set to 60ms - perhaps that is a work around for others too.
Here is a munge :

    function tweakSDP(sdp){
        var lines = sdp.split("\r\n");
        for (var i=0;i<lines.length;i++){
            var line = lines[i];
            if (line.startsWith("a=fmtp:111")){
                lines[i]= "a=fmtp:111 minptime=20; stereo=1; ptime=60; useinbandfec=1;";
            }
        }
        return (lines.join("\r\n"));
    }
