  1. SIP - Ready to Deploy Jim Nelson, Co-CEO

  2. Industry Mandates • A Robust Connection Management Platform Which • Interoperates • Scales • Is extendable • Enables applications

  3. SIP - ‘The Killer App’ • Developed in mmusic Group in IETF • Proposed standard - RFC2543 • Protocol for Session Invitation and Connection Management • Protocol Strengths • Highly scalable • Uses established Internet protocols • Media and transport independent • Enables applications • Highly secure

  4. Two Key Components - Agents • User Agent Client - UAC • Initiate SIP Requests • User Agent Server - UAS • Accepts or Rejects call • Reside in • Softswitches • IP and soft phones • Handheld and wireless devices • DSL/Cable equipment • PBX/UnPBX

  5. Two Key Components - Servers • Proxy Server • Heart of SIP network which contains all service logic • Redirect Server • Returns routing information to the initiating endpoint • Registration • Registration enables subscriber mobility

  6. Primary Place for SIP Services Controls all service logic Central point for location and billing services Internet Integration SIP integrates with web, email and chat applications Call Processing Language XML language for creating services and applications SIP Server Controls Service Logic

  7. Service Provider Networks ITSP’s Long distance carriers Cable MSO’s Firewalls Network address translations Network Access Points Cross network interoperability Where Should SIP Servers Reside?

  8. SIP Is Interoperable • 2 Successful Bake-offs • 15 companies • Began with basic call set up (2 Vendors) • Elevated testing to more advanced features such as; authenticated registrations, multi-hop proxy and media transport • Communication Between Endpoints • Two vendor demo - PingTel • Moving Forward with Interop Testing • Bake-off needs to focus on three-way testing between vendors to better model the needs of a commercial network

  9. SIP is Scalable • SIP Scales to the Internet • HTTP server comparison • Documented SIP Performance Exists • Ability to scale to 500,000 BHCA • Moving Forward with Scalability • Develop performance benchmark • Continued SIP performance from multiple vendors to eliminate any speculation that SIP is ready for deployment NOW

  10. SIP is Extendable • SIP-T - SIP for Telephony Interworking • SIP for intra-softswitch communications • Allows for the bridging of the PSTN and IP networks • CPL - Call Processing Language • Network edge service creation • Allows for the Proxy Server to handle service requests • DCS - Distributed Call State • SIP for cable telephony • Allows for service intelligence to be decentralized

  11. SIP Is Deployable Today!

  12. All This Leads to Applications • Follow-me • Mobility • Internet Call Waiting • Unified Messaging • Call Center • Web/Email Integration

  13. SIP Momentum • Softswitch to Softswitch Communication Using SIP-T • Level (3) • DCS - Cable Industry Support Distributed Call Signaling Using SIP • Packet cable initiative • Vendors and Service Providers are Now Choosing SIP • Softswitches (MGC), gateways, endpoints, application servers • SIP-based networks and services (MCI, Level(3), AT&T)

  14. SIP In the Industry • Consortium Support • International Softswitch Consortium • JAIN • Pulver Test Network • Packet Cable • Recent Articles • Future is SIP, Network Computing, September 20, 1999 • http://www.networkcomputing.com:80/1019/1019colwillis.html • SIP Gains Momentum, Telephony, August 23, 1999 • http://www.internettelephony.com/archive/8.23.99/NOTW.htm#A10 • Getting VoIP off the Ground, PC Week, August 2, 1999 • http://www.zdnet.com/pcweek/stories/jumps/0,4270,410814,00.html
