The third edition has been significantly expanded with brand new chapters on NAT traversal, SIP security, services in SIP, presence and instant messaging, Peer-to-Peer SIP, and an introduction to ABNF and XML. This cutting-edge book shows you how SIP provides a highly-scalable and cost-effective way to offer new and exciting telecommunication feature sets, helping you design your "next generation" network and develop new applications and software stacks. Other key discussions include SIP as a key component in the Internet multimedia conferencing architecture, request and response messages, devices in a typical network, types of servers, SIP headers, comparisons with existing signaling protocols including H.323, related protocols SDP (Session Description Protocol) and RTP (Real-time Transport Protocol), and the future direction of SIP. Detailed call flow diagrams illustrate how this technology works with other protocols such as H.323 and ISUP. Moreover, this book covers SIP RFC 3261 and the complete set of SIP extension RFCs.$cPublisher abstract. 410 0$aArtech House telecommunications library. 517 3 $aUnderstanding the Session Initiation Protocol 606 $aComputer network protocols 606 $aInstant messaging$xComputer programs 606 $aInternet telephony$xComputer programs 606 $aMultimedia systems$xComputer programs 606 $aSession Initiation Protocol (Computer network protocol) 608 $aElectronic books. 615 0$aComputer network protocols. 615 0$aInstant messaging$xComputer programs. 615 0$aInternet telephony$xComputer programs. 615 0$aMultimedia systems$xComputer programs. 615 0$aSession Initiation Protocol (Computer network protocol) 676 $a004.62 676 $a620/.50289 700 $aJohnston$b Alan B.$0523308 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910456683903321 996 $aSIP$91222864 997 $aUNINA LEADER 01891oam 2200481 450 001 9910711719203321 005 20190524132735.0 035 $a(CKB)5470000002486883 035 $a(OCoLC)1045797575 035 $a(EXLCZ)995470000002486883 100 $a20180725d1952 ua 0 101 0 $aeng 135 $aur|n||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aWater levels and artesian pressure in observation wells in the United States in 1949$hPart 1$iNortheastern states /$fprepared under the direction of C.G.
