  1. Gurdeep Singh Pall General Manager Live Communications Group Microsoft Corporation SIP Directions at Microsoft SIP Conference Paris, Jan 21st 2004

  2. Our Vision • Bring “voice”, “screen”, “computation” together to improve: • How calls are initiated and received • How visual information and data are shared during the call • How calls are intelligently routed based on user context and preferences • How communications are archived, indexed, and browsed on-demand • … • With seamless interoperation between communication channels • With seamless interoperation with productivity tools • The goal and challenge are to make such capability pervasive • We believe that this convergence will drive productivity

  3. Unified Communications The End State End User Value • Message Management • Unified communications history • Improved Productivity • Info Agent, PC&Phone, One identity • Multi Device Access • PC, Phone, Cell, PDA • Integrated iWorker experiences • Productivity, CRM, Enterprise, work flow application integration Data People&Groups Info Agent Voice Presence Store, Identity, Media Servers, Relays Email Video IT Manager Value Developer Value Presence IM • Integration of infrastructure • Provisioning, Credentials, Auditing, Policies, Billing, Routing, Operations • Lower TCO • Consolidated extensible Platform • Multimodal capable • Simple, Orthogonal architecture • Lower development costs Speech/Text

  4. Why SIP? • Unified Communications vision mandates a lingua franca that is flexible and broadly understood; ecosystem is key • The first communications protocol that is designed and built around Internet principles; implies unification of at the core around namespace, security • Single protocol, useful in variety of topologies, applications, scenarios • The philosophy of SIP resonates with Microsoft’s vision of Unified Communications; distributed model, smart endpoints key • At this point SIP is a proven technology: both with successes in the industry and our own experiences building products with it

  5. SIP at Microsoft • SIP ships in Windows XP since 2001 • 130M+ served • SIP is the cornerstone of Enterprise Communications products • Live Communications Server 2003 • “Vienna” and “Istanbul” 2004 • Federation and connectivity with MSN Messenger Service • SIP is becoming the cornerstone of MSN Messenger Service • Today used for pc-phone and video calling • Goal is to move 100M users to SIP for all services (IM, voice, video) in 2006 timeframe • SIP is planned to be included in “Longhorn” the next major update to Windows SIP has gone beyond “boutique” status to become a core, mission critical component used by variety of applications & services across Microsoft

  6. Products and Standards Timeline *PIDF - <draft-ietf-impp-cpim-pidf-0x.txt>

  7. SIP Ecosystem and Microsoft

  8. Standards: Focus areas for Microsoft • Remote Control • Scenario: Integration with IP and TDM PBXs • We are considering the following approaches: • ECMA-323 XML messages transported over SIP (session and events) • Using REFER with additional semantics and expanding SIP Event Packages • Conferencing • Basic conferencing with SIP • http://www.ietf.org/internet-drafts/draft-ietf-sipping-cc-conferencing-02.txt • XCON for centralized conferencing • http://www.ietf.org/html.charters/xcon-charter.html • Security • Hop-by-hop auth and privacy using TLS is the de facto standard • End-to-end security becomes more important with federated scenarios • S/MIME is an option but PKI has deployment challenges

  9. Standards: where can we improve • Presence, many protocols, a world divided • Numerous standardization bodies and consortiums, some with multiple protocols! • Lack of consistency is going to slow down pervasive connectivity • Important that SIP becomes the universal connector for federation between networks • SIMPLE WG Issues • Slow pace hurting SIMPLE camp • We would like to see SIMPLE address different interfaces • wireless client-to-server, enterprise client-to-server, common federated server-to-server • Architectural direction – peer to peer yesterday, client/server driven by wireless scenarios today, tomorrow? • Instant Messaging directions • MESSAGE Page Mode? Session Mode? • MS(R)P (Message Session Relay Protocol)?

  10. In Conclusion • SIP is a Big Bet for Microsoft • A healthy SIP Ecosystem is critical for the industry and for Microsoft • Many innovations depend upon the SIP foundations • Industry must rally together to remove obstacles and improve pace of innovation
