title: Open source RTP mixer/translator exe or sdk
body: <p>Hi I need opens source (win 32) sdk or free server with signaling protocol, which implements RTP translator or mixer. e.g receives RTP traffic from one connection and transmits it on the other. Does not have to have conferencing capabilities. </p>
  
  <p>Server should implement some kind of protocol which opens, bridges, and closes connections.</p>
  
  <p>Ready made server is much preferable than just common RTP SDK. </p>
