Protocols SIP (Session Initiation Protocol)
Tool Wireshark, TitanSIM,
References RFC (3261)
Project Detail The Session Initiation Protocol (SIP) is a signaling protocol for
initiating, managing and terminating voice and video sessions across
packet networks. These sessions include Internet multimedia
conferences, Internet telephone calls and multimedia distribution.
Members in a session can communicate via multicast or via a mesh of
uncast relations, or a combination of these.
The protocol can be compressed by using Signaling Compression. SIP
invitations used to create sessions carry session descriptions which
allow participants to agree on a set of compatible media types. SIP

3. supports user mobility by proxying and redirecting requests to the
user's current location. Users can register their current location. SIP is
not tied to any particular conference control protocol. SIP is designed
to be independent of the lower-layer transport protocol and can be
extended with additional capabilities.
