SylkServer official web site is http://sylkserver.com


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 language.


SylkServer is an application server that behaves like a SIP end-point and therefore must be deployed behind a SIP Proxy/Registrar server for registration, proxy, presence agent, accounting and authorization functions. The SIP Proxy must be configured to route certain flows to SylkServer and handle incoming requests from it as necessary.
