 Description: A state of the art, extensible SIP Application Server
  SylkServer allows creation and delivery of rich multimedia applications
  accessed by SIP User Agents.  The server supports SIP signaling over TLS,
  TCP and UDP transports, RTP and MSRP media planes, has built in
  capabilities for creating ad-hoc SIP multimedia conferences with HD Audio,
  IM and File Transfer and can be easily extended with other applications by
  using Python programming language.
