Yate represents calls internally as messages with parameters (caller, callee, codecs …) .

The sems is a light sip engine server with several applications (like

sems server for doing b2bua like this:</div><div><br></div><div>Incoming<=======>Kamailio<========>Sems<========>Kamailio<=======>outgoing</div><div><br></div><div>2- In sems, you could disable rtp realying.
