Conferencing Scenarios

Rich conference calls Work with people anywhere

Effective Team Meetings Professional Presentations

End to End Web Conferencing User Experience
• Ad-hoc conferencing from IM and Phone
• Scheduled meetings, Joining, Presentations

DEMO
Deploying Web Conferencing
Consider Voice and Web Conferencing scale as part of front end planning
Plan Server Roles & Capacity 250 active desktop/application sharing users (5 per conference) per machine

Plan/improve network capacity based on Voice/Video/Desktop Sharing usage

Consider Network usage

Plan in-band settings to enable/disable features based on needs, network capacity

Plan client features 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”

Users continue with current clients until ready for next step
Migrate Users 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

Deployment Considerations
Pre-requisites for Users migrated to W14 Users get new
migration pool Communicator
• Apply necessary Cumulative • Move users to W14 Pool • New clients:
Update (CUs) • Users have either W12 or • Users start migrating to
• Latest CU for Outlook Add- W13 clients use W14 clients and
In and Live Meeting to all • No CVC check admins support them
users • Communicator Attendee • MVMPOP
• Latest CU for W12 and and Web App • W12 and W13 clients still
W13 • Training/support when supported
• Latest CU applied to all first pool rolls out • CVC check to force
W13 frontend servers • Web Access Server W13 upgrades
• Leave as-is for web based
IM/P support
Migration – Scheduling

Users migrated to CS Users get new Live Meeting

W14 pool Communicator client

• User has W13 addin • Existing meetings on • Works as expected

only calendar continue to
• Conferences and work
Meetings scheduled • User now has both
with W13 addin W13 and W14 addins
continue as normal installed, but sees
only W14 addin
• New meetings use
W14 HTTPS links
• Can’t schedule new
on-prem Live
Meetings
Migration - Join
Users migrated to W14 pool Users get new Communicator
client
• Migrated meetings continue to behave • New meetings:
like W13 meetings: • Everyone joins with HTTPS link
• No Lobby • The Launch page:
• Federated users • Launches Communicator “14”, or
• Existing access numbers and Communicator Attendee “14” if
conference IDs migrate and work as installed
expected • 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
Audio Conferencing Drilldown
Meeting types
(from Gartnerreport)

85% <10% <5%

• Reservationless calling • Operator assisted • Managed event, external
• 25 or fewer participants • Roll call, polling • Transcription, high touch,
• One-off or Weekly staff, ½ - 2 hrs, usually with • 25-100 participants large audiences
Web attached, intl. participation by company Biweekly/monthly with • 100+ participants,
Web attached Quarterly, Web attached

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

• Globally or per site*

Configure access numbers • Order of access numbers per conference region (PowerScript cmdlet only)*

Configure DTMF commands* • Globally or per site

Configure PIN security settings • Complexity, expiration, etc.

• Populate correct phone numbers for users (msRTCSIP-Line property)

Enable users for PSTN dial-in • 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

Coexistence with OCS 2007 R2

Call picked up by Conference homed in other 2007R2 pool Conference homed in other W14 pool
OCS 2007 R2 CA No transfer Transfer
W14 CA No transfer Transfer
 Migration Steps
Getting to coexistence Coexisting phase: Decommissioning
state months or years W13 pools

• Deploy latest CU to all OCS • W13 access numbers • Migrate COs so that
2007R2 FEs still around they point to a W14
• Move data from OCS • W14 access numbers pool instead of the
2007R2 WMI to W14 starting to be added W13 pool, using
SQUID using PowerShell • Any user can call any PowerShell cmdlets
cmdlets access number to join • Meeting invites
• Move users to W14 pool any meeting that still have W13
(their meetings are (interpool transfer) access numbers will
automatically migrated • Some meetings have now be handled by
also) old invites with W13 CAA14
access numbers • Decommission W13
• New meetings have pool
W14 access numbers
Audio Conferencing: Scale SUBJECT TO CHANGE!
Per-pool Limits (10 FEs/pool): Limit of 6000 simultaneous users per
80 000 users/pool pool:
Max meeting size 250 900 users in PSTN-only meetings
2100 more users in VoIP-only meetings
2400 more users in mixed meetings:
1800 using OC, 600 using PSTN

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
