  2. Session Initiation Protocol SIP can be called a “rendezvous” protocol. That is, it allows endpoints on the Internet to discover, locate, negotiate, and establish sessions. What kind of sessions? Any kind of sessions. SIP is used to establish VoIP (of course), video, gaming, text, call control. SIP is an open protocol standard, with an active working group on the Internet Engineering Task Force (IETF). Avaya and other major companies are active in the IETF SIP working group and in other industry groups, working to ensure that SIP-enabled solutions work across businesses and enterprises with a variety of legacy, new, and evolving networking and telecommunications infrastructures and products to enhance and revolutionize the world of real-time business communications. SIP is used to identify, locate, and enjoin parties who want to communicate using any peer-to-peer media type. However, SIP does not transport the media itself: That is handled by codecs within the communications programs or devices.

  3. Gartner Hype Cycle – Where is SIP?

  4. Important SIP Characteristics • Born of the Internet • Made for mobility • Media agnostic (Separation of signaling and media) • Ability to support multiple media within the same session • Text-based and extensible (Heterogeneity is the norm) • Standard APIs “SIP is probably the third great protocol of the Internet, after TCP/IP and HTTP” - Vinton Cerf, “Father” of the Internet

  5. SIP Elements • User Agents (UA): Endpoint devices that originate or terminate the SIP signaling. They can be clients (UAC) that initiates a request, or a server (UAS) that terminates a request (most endpoints do both) • Proxies route SIP requests to their destination. They sit in the signaling path between endpoints, and may add parameters to a request or reject a request, but they do not initiate requests • Registrars handle REGISTER requests from endpoints to bind a user to the device. This information is then stored in a location service database for the proxy’s domain. • Back-to-Back User Agent(B2BUA): Similar to a proxy, except that it terminates the SIP dialog on both sides. Commonly used to provide services because it can manipulate the signaling between endpoints

  6. SIP Addressing/RegistrationSIP Connects People to People, not Device to Device Cell Phone How do I reach Jim? Just use sip:jim.su@quagga.com I am ready to take calls My ID: sip:jim.su@quagga.com Location: 5054@212.55.34.2 Desk Phone 212.55.34.2 Location Service Registrar IM Client

MM MX 3rd Pty VP CM SessionManager SIP Rich Communications Not Limited to the EnterpriseA More Complete User Experience – Extended to Your Customers 3G SIP Smart Phones Mobile Customer Care Voice Conference Web Conference Whiteboard Interactive Voice Interactive Video Unified Communications Voice 3G Mobile Network 3G Gateway • Session Manager Rich Communications • Media/session independence • Add new media without impacting existing services • Loosely coupled feature servers • Self-service IVR with video previews • Send information and images along with audio

  10. SIP ExtensibilityPrinciple: Heterogeneity is the Norm • SIP can be extended by adding new headers, methods, parameters, or bodies – without a dramatic impact on existing systems • Proxies only need to understand 3 core SIP methods (INVITE/CANCEL/ACK) – addition of new methods have no impact • New content types have no impact on proxy operation • Built-in mechanisms enable forward compatibility between clients and servers while minimizing possible interoperability breaks • Clients/servers are expected to NOT assume universal support for new extensions

  21. Introducing the SIP Session Manager Global Routing Policy

  22. A Rather Special SIP Routing and Integration Engine • Establishes an Open, Interoperable SIP Network • Integrates disparate PBX/Key systems into a single communication network • Normalizes SIP into a common, open implementation • Pools and shares global trunking resources • Fully leverages SIP trunk services from ITSPs • Manages a Global Network Dial Plan • Local PBX dial plans don’t change • Adapts to existing dial plans that overlap or have different digit patterns • One point of administration to handle dialplan changes between systems
