Session Initiation Protocol :SIP Application layer protocal
eduguru 0 Comments and accepted. Redirection (3xx): Further action needs to be taken (typically by sender) to complete the request. Client Error (4xx): The request contains bad syntax or cannot be fulfilled at the serve, fax over IP and online games. Originally designed by Henning Schulzrinne and Mark Handley in 1996, file transfer, incorporating many elements of the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP).[2] SIP works in conjunction with several other application layer protocols that iden, instant messaging, modifying and terminating sessions consisting of one or several media streams. SIP can be used for two-party (unicast) or multiparty (multicast) sessions. Other SIP applications include video conferen, presence information, Session Initiation Protocol :SIP Application layer protocal, SIP has been developed and standardized in RFC 3261 under the auspices of the Internet Engineering Task Force (IETF). It is an application layer protocol designed to be independent of the underlying t, streaming multimedia distribution, termination and other essential elements of a call. SIP can be used for creating, the protocol may be encrypted with Transport Layer Security (TLS). List of SIP request methods REGISTER: Used by a UA to indicate its current IP address and the URLs for which it would like to receive, The Session Initiation Protocol (SIP) is a signaling communications protocol, understood, User Datagram Protocol (UDP) or Stream Control Transmission Protocol (SCTP).[1] It is a text-based protocol, video) SIP typically employs the Real-time Transport Protocol (RTP) or Secure Real-time Transport Protocol (SRTP). For secure transmissions of SIP messages, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) networks. The protocol defines the messages that are sent between endpoints whic, without setting up a call. A new method has been introduced in SIP in RFC 3262:[14] PRACK (Provisional Response Acknowledgement): PRACK improves network reliability by adding an acknowledgement system
