SylkServer 2.3.0 release

Added by Adrian Georgescu over 11 years ago

  • SIP users can create ad-hoc conference rooms using SylkServer MSRP chat and invite users from both SIP and XMPP domains
  • XMPP users can create multiparty conferences using SylkServer MUC capability and invite users from both XMPP and SIP worlds
