<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thank you for your help about the concept of TLS & SIPS.</FONT></DIV>
<DIV><FONT size=2 face=Arial>I still confuse with the scenerio of how to use SIPS/TLS to make security VoIP by Opensips.</FONT></DIV>
<DIV><FONT size=2 face=Arial>I got the information like following from console after run opensips 1.4.0 with TLS enabled.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV>Listening on<BR> udp: 192.168.1.11 [192.168.1.11]:5060<BR> tcp: 192.168.1.11 [192.168.1.11]:5060<BR> tls: 192.168.1.11 [192.168.1.11]:5061<BR>Aliases:<BR> tls: wavehost:5061<BR> tcp: wavehost:5060<BR> udp: wavehost:5060</DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>As RFC3261 said, 5061 is default port for SIP. So, there are two ports here after TLS enabled. My question is how to configure my UA to use the SIP server?</FONT></DIV>
<DIV><FONT size=2 face=Arial>In the other word, how to use SIP server with TLS enabled? My UA is SJphone 1.6, seems it doesn't support SIPs/TLS. Is there any open source SIP UA which support TLS availiable ?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
