The Session Initiation Protocol (SIP) is a protocol for establishing real time communication sessions with one or more participants. Its most frequently used for voice communications but it can handle video as well as future applications. SIP was designed to be independent of the transport layer, i.e it can work on UDP, TCP or STCP. All voice/video communications take place via another protocol, usually RTP. There are many RFCs surrounding SIP, but the most important one is RFC 3261. SIP is a text based protocol that looks and acts very much like the HTTP protocol. The original designers (Henning Schulzrinne & Mark Handley) wanted to make a protocol that had its roots in the IP world, rather then in the telecommunications world. SIP has been an amazing success, and has become the major driver in the adoption of VoIP and Internet Telephony in recent years. All major manufacturers have adopted the standard annd SIP software and hardware. SIP servers are responsible for setting up calls between SIP devices. SIP servers usually combine several of the SIP server functions such as SIP proxy and SIP registrar into one piece of software. Hubify is both a SIP proxy and a SIP registrar as well as a media server in order to also handle real time voice communications.
