摘要: The session initiation protocol (SIP) is used to establish calls/sessions between end-points. The type of session to be established is described by the session description protocol (SDP), RFC 2327. At present however, RFC 2327 only contains parameters that describe audio or video sessions. The expansion according to the invention of the SDP by corresponding parameters that describe file sharing sessions thus permits file sharing sessions to be established using the SIP.
