              // change ip to your servers IP address!

              { ip: '127.0.0.1', announcedIp: '102.42.239.215' }

          ],

          initialAvailableOutgoingBitrate : 1000000,

          minimumAvailableOutgoingBitrate : 600000,

          // Additional options that are not part of WebRtcTransportOptions.

          maxIncomingBitrate              : 1500000,
