  9. Presence Applications Services—Overview

  10. Presence and Communications • The primary use for presence information is to facilitate communication • The best way (but not the only way) to derive presence information is by monitoring communications Communications Presence

  11. The Three Stages of AllPresence Information Publish Collect Consume • Value increases quadratically with number of actors • Challenge is to connect them all Keyboards Phones Wireless AP Motion Sensors Network Storage Aggregation Policy Privacy Synchronization Desktop Apps PBX Calendar Collaboration Phone

  12. IBM Sametime Servers Inside a Single Enterprise:Standards-Based Interoperability IBM Presence Cisco Unified Presence Server SIP/SIMPLE Microsoft Presence Sametime Client Office and Messenger

  13. Presence and SIP/SIMPLE Interoperability • Peer—Peer Relationship via Standardized Protocol • Symmetrical Relationship—Data exchanged both ways to enhance Cisco customer experience with Cisco featuresas well as SIP/SIMPLE Enterprise services Live Communication Server Presence Applications Services Presence Voice, Video, IM Enterprise Desktop Cisco Enterprise Solution

  15. Cisco Is Committed to Making it Work… Innovating and Standardizing • Cisco leads key IETF SIP working groups: SIP, SIPPING, IPTEL, ENUM, MIDCOM, BEHAVE • Cisco leads efforts to standardize solutions to the “hard” problems… QoS, NAT/FW traversal, Secure Media and Signaling • Cisco has influenced nearly all voice RFCs • Cisco has authored or co-authored more SIP-related drafts and RFCs than any other company Develop Products Develop Standards Deploy With Customers

  16. Cisco SIP Standards Leaders • Cullen Jennings RAI Area Director • Dean Willis—SIP and SIPPING WGco-chair • Cullen Jennings—IPTEL, Behave, WebDAV WG co-chair • Patrik Faltstrom—ENUM WG co-chair • Melinda Shore—MIDCOM WG co-chair • Dave Oran—Speech SC WG co-chair • Mark Lindner - ECRIT co-chair • Dave Meyers - SpeerMint • James Polk—NENA (non IETF) co-chair • Jonathan Rosenberg—IAB

  17. What does “Ready” mean? • Typical progression of Idea • Mailing list discussion Very Fluid 0-infinity • Individual Internet-Draft Muddy 2-12 months • Working Group Internet-Draft Moist Clay 4-12 months • Working Group Last Call Solid 1-2 months • AD Review Solid 0-6 months • IETF Last Call Very Stable 1 month • IESG Review Very Stable 1-6 months • RFC-Editor Queue Ready 3-6 months • Published as RFC Ready • Informational • BCP • Standards Track (Proposed, Draft, Full Standards)

  18. Cisco Unified CallManager 5.0:SIP and Presence Integration

  19. A Bit of History ………… • 10 years ago, there were only traditional PBXs. • Today, the market would still be traditional PBXs if Cisco didn’t disrupt that market and build something better on an IP core. • To disrupt this market, Cisco’s first focus was to compete with PBX manufactures on their level • Build an IP-PBX equivalent to any PBX on the market. • At the time Cisco began work on Cisco Unified CallManager, • standardizing VoIP protocols were too immature to replicate • PBX features. • Cisco had to develop SCCP protocol to address the difficult issues and build that IP-PBX. • At the same time, we also have focused on the IETF standards body solving the difficult • SIP problems (SIP and SIPING WG leads, RFCs, etc…). • SIP is now ready to support the services and capabilities for the • Cisco Unified Communication system

  20. Cisco’s Product Integration of SIP Cisco Unified Presence Server Enhanced SIP Services Cisco Unified CallManager Cisco Unified Personal Communicator Cisco Unified MeetingPlace SIP proxy, SIP softswitch Cisco Unity SIP Phones- 40/60, 05/12. ATA Cisco Unified Enhanced IP Phones IOS Gateways PIX 2000 2003 SIP Next Generation Services SIP Integration into Enterprise Solution 2005 SIP Proof of Concept

  21. Key Guidelines for SIP Integration in Cisco Unified CallManager 5.0 • Preserve customer investment in Cisco Unified Communications system infrastructure during introduction of SIP based communications over 7 million phones, over 37,000 IPC customers • Allow at-your-pace customer migration to new capabilities provide seamless interoperability between SIP and SCCP • Continue to support existing features while introducing new SIP features must be feature parity between SIP and SCCP

  25. Guidelines for Presence IntegrationCisco Unified CallManager 5.0 • Presence Integration into the Infrastructure • Allows Presence to be used for both Cisco Unified CallManager internal features as well as Services in a Presence enabled IP Network • Allows for collection and passing of Cisco Unified CallManager internal status for any Cisco Unified IP Phone – both SIP and SCCP • Standards Based using SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) based • Supports Presence Event Package, Presence Information Data Format (PDIF), Rich Presence Extensions (RPID) • Allows for Interoperability with any SIMPLE based presence network • Provide Initial Presence Features • Proof of Presence Integration • Continue to provide more Presence Features to Cisco Unified CallManager in Future Releases

  26. Description Status Icon SpeedDial Unknown BLF SpeedDial Busy BLF SpeedDial Idle Initial Presence FeaturesCisco Unified CallManager 5.0 • Use Presence to Support Speed Dial Keys (Similar to Busy Lamp Field (BLF) feature) • Presence Enable Call Lists • Missed Calls, Received Calls, Placed Calls • Presence Enable Directories • Corporate Directories
