<div dir="ltr"><p><font face="courier new,monospace">Hi,</font></p>
<p><font face="courier new,monospace">I am currently trying to make Secure RTP calls between my SIP client and the eyeBeam. When eyeBeam is configured for encrypted calls, it uses Secure RTP for media and TLS for SIP signalling.</font></p>
<p><font face="courier new,monospace">I have configured the OpenSIPs server with TLS support.</font></p>
<p><font face="courier new,monospace">The scenario is as shown below:</font></p>
<p><br><font face="courier new,monospace"> ---------------- UDP ------------------ TLS -------------<br>| My SIP Client | <-----> | OpenSIPs Server | <-----> | eyeBeam 1.5 |<br> ---------------- ------------------ -------------<br>
Linux Machine Linux Machine Widows XP machine </font></p>
<p><font face="courier new,monospace">When a call is made from eyeBeam to My SIP client the call gets established properly and the OpenSIPs server acts as a gateway.</font></p>
<p><font face="courier new,monospace">But when a call is made from My SIP client to eyeBeam the OpenSIPs returns the <strong>477 Send failed</strong> response to My SIP client.</font></p>
<p><font face="courier new,monospace">By enabling the debug informaiton on OpenSIPs server, I found that it couldn't do TLS handshake with the eyeBeam and so couldn't send the SIP Request from My SIP client to the eyeBeam.</font></p>
<p><font face="courier new,monospace">In brief the OpenSIPs server can accept the inbound messages via TLS but <strong>it can't send outbound messages via TLS</strong>.</font></p>
<p><font face="courier new,monospace">Can anybody help me to resolve this problem? Please see my opensips.cfg file and OpenSIPs server logs attached with this mail.</font></p>
<p><font face="courier new,monospace">Thanks,<br>NT<br> </font></p></div>
