[SIP Beyond VoIP] Configure sylkserver to use TLS with xmpp im server

[Pranathi Venkatayogi]

Hi,
  I am connecting Skylserver with Cisco Jabber server, which requires TLS for federation. When sip message is being sent to IM Server, I get the stream error - " TLS is required on this stream". Full xmpp stream trace is as below.
  Can someone tell me how to configure sylkserver to start using TLS?

Thanks
Pranathi
