title: Plivo "Bad Media Description Error"
body: <p>I'm using Plivo WebRTC to make and received VoIP calls. Sometimes when I use Plivo.conn.call from JS SDK to start a call a get "Bad Media Description" error. This happens once every five to ten calls. Does anybody knows what "Bad Media Description" error means? Has anyone had this problem?</p>
