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

2. 2 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. 3 3 Data Email IM Video Voice Store, Identity, Media Servers, Relays Info Agent Speech/Text End User Value IT Manager Value Developer Value Message Management Unified communications history Improved Productivity Info Agent, PC&Phone, One identity Multi Device Access PC, Phone, Cell, PDA Integration of infrastructure Provisioning, Credentials, Auditing, Policies, Billing, Routing, Operations Lower TCO Consolidated extensible Platform Multimodal capable Simple, Orthogonal architecture Lower development costs Unified Communications The End State People&Groups Integrated iWorker experiences Productivity, CRM, Enterprise, work flow application integration Presence

4. 4 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. 5 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. 6 6 Products and Standards Timeline *PIDF -

7. 7 7 SIP Ecosystem and Microsoft

8. 8 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. 9 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. 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
