  12. Conferencing Support in Lync 2010 clients

  13. Video – Supported Formats • HD • High Definition • 1280x720(16:9), 25 fps, 1.5 Mbps • Quad Core > 2 GHz • CIF • Common Interchange Format • 352x288, 15 fps, 350 kbps • Single Core > 1.5GHz • VGA • Video Graphics Array • 640x480, 25 fps, 700 kbps • Dual Core > 1.9GHz • Panorama • Polycom CX5000 RoundTable • 1056x144 (22:3), 15 fps, 350 kbps • Single Core > 2 GHz

  14. VoIP and Video – Bandwidth Requirements

  15. Conferencing Details

  16. On-premise Audio Conferencing • Replaces ACP for ~85% of calls (Gartner) • Requires PSTN Gateway deployment on premise • Features • Name Recording, Entry/Exit announcements (default OFF) • Supports Lobby for easy join (Presenters grant access) • Easy PIN management, default no expiry • Recording from Lync client • Rich language support for IVR • Per-pool Limits (10 FEs/pool):80K users/pool, max mtg:250 • Limit of 6000 simultaneous users per pool: • 900 PSTN-only meetings, 2100 in VoIP-only, 2400 mixed

  17. Online (ACP) Audio Conferencing • Sign up with an ACP partner • Initially British Telecom, InterCall, Premier Global • Integrates automatically with VoIP users via VoIP bridge • Features • Dial-in from phone (details in invite, and conversation window) • Dial-out to self and others via ACP • Mute individuals from Lync • Eject individuals from Lync • End conference (ends for all Lync and PSTN users) • DTMF tones via ACP for Mute, Unmute

  18. Web Conferencing • Scale to 250 users per meeting • Screen sharing (256, 1000, 3500 kbps) • Supports P2P to reduce server traffic • Share Desktop, single app, multiple apps • Controllable via in-band policy settings • PowerPoint (20, 200, 500 kbps) • Converts to PPT 2003 and DHTML (web app), removes AV • Rich transitions, asynchronous navigation • Whiteboard/PPT Annotations (20, 200, 500 kbps) • Text support for note taking, clipboard support, images

  19. Manageability

  20. Manageability • Clients can now be managed using Lync Server Control Panel, the Windows PowerShell command-line interface, or both. Settings are sent to clients using in-band provisioning as opposed to group policies.

  21. Troubleshooting

  22. Client Troubleshooting • Call Quality Notifications to end user (next slides) • Logging • Enabled/disabled by policy/in-band setting • User can turn on/off in Options dialog if no policy set • Written to %userprofile%/tracing • Tools to analyze logs • Collect Logs • Packages logs into ZIP file with screen shot, voice sample • Enabled via regkey or policy/in-band setting • User sends to their IT admin on their own • Call Detail Records & Reporting on Server (on-premise)

  23. Events and Measurements Call Quality Notifications

  24. Events and Measurements Call Quality Notifications (cont.)

  25. CDR & Reporting improvements • MS diagnostics aka “msdiags” included with all SIP 4xx, 5xx, 6xx, BYEs • ms-diagnostic:<error code>;reason=“xxx”;description=“yyy”;source=“zzz” [;custom-param=“foo”] • Msdiags are: • Specific – one error code per distinguishable failure case • Admin Friendly – They describe failure from end user point of view; not in terms of internal implementation details, use official product nomenclature for server names (no hex codes) • Actionable – Many msdiags contain troubleshooting steps • Categorized – Success, UnExpectedFailure, ExpectedFailure • Greatly improved reliability reports on the monitoring server

  26. Lync in Office 365

  27. Online vs. On-premise Key Differences
