End to End Web Conferencing User Experience Ad-hoc conferencing from IM and Phone Scheduled meetings, Joining, Presentations DEMO
Deploying Web Conferencing • Plan Server Roles & Capacity • Consider Voice and Web Conferencing scale as part of front end planning • 250 active desktop/application sharing users (5 per conference) per machine • Consider Network usage • Plan/improve network capacity based on Voice/Video/Desktop Sharing usage • Plan client features • Plan in-band settings to enable/disable features based on needs, network capacity • Edge server required for outside (authenticated and anonymous) users • Roll out Cumulative Updates • Apply CUs to W13 Front Ends, Communicator and Live Meeting to current desktops Deploy Servers • Step-wise migration from previous server version to CS “14” • Migrate Users • Users continue with current clients until ready for next step • Can migrate previous content using resource kit tools • Deploy clients • Push clients, or use version check and allow users to download (on-prem or WU)
Topologies • Prescriptive guidance based on scale, workloads • 5K to 80K per pool • Configurable features based on needs & licensing • Enterpise Edition (EE) for large scale, Standard Edition for small scale
Supported Topology - EE pool with separate AV Conf Server pool • Ideal for • Large enterprise • Data center deployment • Scalability • Up to 80,000 users • 250 user large conferences • Conferencing functionalities • Audio/Video Conference • Web Conference (slide sharing, application sharing, whiteboard, etc.) • PSTN dial-in (requires mediation server and PSTN gateway) • Group IM • CWA
Supported Topology - EE pool with co-located AV Conf Server pool • Ideal for • Medium size business • Regional Deployment • Scalability • Up to 10,000 users • 250 user large conferences
Supported Topology - SE pool • Ideal for • Proof of concept • Large branch office • Scalability • Up to 5,000 users • 250 user large conferences

Deployment Considerations • Pre-requisites for migration • Users migrated to W14 pool • Users get new Communicator • Apply necessary Cumulative Update (CUs) • Latest CU for Outlook Add-In and Live Meeting to all users • Latest CU for W12 and W13 • Latest CU applied to all W13 frontend servers • Move users to W14 Pool • Users have either W12 or W13 clients • No CVC check • Communicator Attendee and Web App • Training/support when first pool rolls out • Web Access Server W13 • Leave as-is for web based IM/P support • New clients: • Users start migrating to use W14 clients and admins support them • MVMPOP • W12 and W13 clients still supported • CVC check to force upgrades
Migration – Scheduling • Users migrated to CS W14 pool • Users get new Communicator client • Live Meeting • User has W13 addin only • Conferences and Meetings scheduled with W13 addin continue as normal • Existing meetings on calendar continue to work • User now has both W13 and W14 addins installed, but sees only W14 addin • New meetings use W14 HTTPS links • Can’t schedule new on-prem Live Meetings • Works as expected
Migration - Join • Users migrated to W14 pool • Users get new Communicator client • Migrated meetings continue to behave like W13 meetings: • No Lobby • Federated users • Existing access numbers and conference IDs migrate and work as expected • New meetings: • Everyone joins with HTTPS link • The Launch page: • Launches Communicator “14”, or Communicator Attendee “14” if installed • Otherwise, auto-join using Communicator Web App • Admin setting to allow CONF: join with previous client versions • Access numbers: • Anyone can call any access number to join any meeting • Users get a new conference ID
Archiving & Compliance • Can Archive: • Meeting attendance & roles • Content added/shared/deleted/slide flips • Annotation contributions • Original content files and attachments • Transcript of meeting • Can control: • Turn on/off annotations • Desktop/Application Sharing and Encryption • Enable/Disable web conferencing • Polling • File Transfer / Attachments
Meeting types(from Gartner report) • Reservationless calling • 25 or fewer participants • One-off or Weekly staff, ½ - 2 hrs, usually with Web attached, intl. participation by company • Operator assisted • Roll call, polling • 25-100 participants Biweekly/monthly with Web attached • Managed event, external • Transcription, high touch, large audiences • 100+ participants, Quarterly, Web attached 85% <10% <5% Our target Stay on ACPs • Features needed for small/med.meetings • Simple and reliable join • Best in class UX on both the PSTN and soft client side
New Audio Conferencing Features in W14 • Provide all the features needed to handle small/mid-size meetings • DTMF controls • Entry/exit announcements • Make join simpler and more reliable • Lobby support for restricted meetings • Name recording for unauthenticated users • PIN improvements: default no expiration, e-mail notification, increased visibility • Provide a best in class UX on both the PSTN and soft client side • Control entry/exit announcements at schedule time and during conference • Recording of reservationless meetings

Deploying PSTN Dial-in • Plan Numbers and Capacity • Add DID numbers and PSTN trunk capacity • Configure Dial Plans • Configure dial-in conferencing regions • Deploy Gateways • PSTN gateways or configure SIP trunking • Configure access numbers • Globally or per site* • Order of access numbers per conference region (PowerScript cmdlet only)* • Configure DTMF commands* • Globally or per site • Configure PIN security settings • Complexity, expiration, etc. • Enable users for PSTN dial-in • Populate correct phone numbers for users (msRTCSIP-Line property) • Generate PIN and send welcome email via script * New in CS 14
Coexistence with OCS 2007 R2: Inter-pool Transfer • Problem: • All Conference Attendant (CA) access numbers globally available • User can call 2007R2 CA trying to join a conference hosted on W14 pool. • OCS 2007R2 CA cannot handle lobby (disconnects call) • Solution: • “Inter-pool transfer” transfers the call to W14 CA after conference ID has been entered, preserving language selection • On OCS 2007 R2 front-ends, requires cumulative update #5 or higher • CA will only accept transfers from another CA, will only transfer if meeting homed in W14 pool
Migration Steps • Coexisting phase: months or years • Decommissioning W13 pools • Getting to coexistence state • Deploy latest CU to all OCS 2007R2 FEs • Move data from OCS 2007R2 WMI to W14 SQUID using PowerShell cmdlets • Move users to W14 pool (their meetings are automatically migrated also) • W13 access numbers still around • W14 access numbers starting to be added • Any user can call any access number to join any meeting(interpool transfer) • Some meetings have old invites with W13 access numbers • New meetings have W14 access numbers • Migrate COs so that they point to a W14 pool instead of the W13 pool, using PowerShell cmdlets • Meeting invites that still have W13 access numbers will now be handled by CAA14 • Decommission W13 pool
Audio Conferencing: Scale SUBJECT TO CHANGE! Per-pool Limits (10 FEs/pool): • 80 000 users/pool • Max meeting size 250 Limit of 6000 simultaneous users per pool: • 900 users in PSTN-only meetings • 2100 more users in VoIP-only meetings • 2400 more users in mixed meetings: 1800 using OC, 600 using PSTN CPS RGS / AS CPS RGS / AS CAA CAS CAA CAS Front End Front End Back end Pool (up to 10 FEs)
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 • For a whole lot more on this: session UNC316, today, this room, 1:30pm
Top 5 takeaways • True unified client – one client handles both Web and Audio Conferencing • Everyone joins easily with the new lobby feature • Move 85% of your ACP conferences to Communications Server “14” • Start planning your deployment and migration early – lots of information and tools available to help • Flexible topologies supported to meet your organization’s needs
