I have tried to read the tutorial (tls.html) from <!-- w --><A href="http://www.openser.org./" target=_blank>www.openser.org.</A><!-- w --> <BR>I have read it many times. But, I still confused to undestand it. Would you mind help me, Please? <BR><BR>Here are my questions: <BR>1. How can we evidence that the communication that using TLS is secure communication? (Real proof) <BR>2. When using TLS, how can we know that the communication has been eavesdropped? <BR>3. Is TLS just use port 5061? If yes? How can TLS can protect the communication from sniffer who knows TLS using port 5061? <BR>4. What kind of type encryption that TLS use?</div> <div>5. What sofware that we can use to test for making a call in opeser with TLS support? I have tried minisip, but I always get error message..Please... <BR><BR>I realize that my undestanding
