Toshiba Confidential SESSION INITIATION PROTOCOL Presented by: Philipe BC DaSilva 1 Toshiba Confidential WHAT IS SIP? SIP is open, non-proprietary standard.

Developed by IETF (Internet Engineering Task Force). The Session Initiation Protocol (SIP) is the IETF standard for the establishment of multimedia sessions such audio, video, instant messaging, or real-time data communication sessions. Seamlessly integrates with the internet. SIP is a text-based protocol, similar to HTTP and SMTP, for initiating interactive communication sessions between users. 2 Toshiba Confidential

WHAT IS SIP? SIP is truly an internet-model protocol using ADCII message based on HTTP. SIP support URL (with DNS). Easy to decode and troubleshoot , it means web-type applications can support SIP services with minimal changes. Easy integration and ability to inter-operate with other protocols and vendors. SIP is flexible and scalable VoIP solutions. Call setup is quick and incurs low overhead. The handshake and data exchange to initiate a call is minimal compare to H.323.

3 Toshiba Confidential Integration with IETF Other IETF protocol standards can be used to build a SIP based application. SIP can works with existing IETF protocols, for example: RTP Real Time Protocol -to transport real time data and provide QOS feedback. RTSP Real Time Streaming Protocol - for controlling delivery of streaming media. SAP Session Advertisement Protocol - for advertising multimedia session via multicast.

SDP Session Description Protocol for describing multimedia sessions. MIME Multipurpose Internet Mail Extension standard for describing content on the Internet. HTTP Hypertext Transfer Protocol - HTTP is the standard protocol used for serving web pages over the Internet. 4 Toshiba Confidential SIP Architecture SIP Gateway
