Agenda Feature overview Deployment and server configuration End user administration Demo Call Flows Reporting Bringing it together Q&A

Office Communications Server 2007 Where Do We Play? PBX Functionality N-way conferencing “Conference” button on the desktop phone Bridge functionality Similar to that provided by ACPs Audio Conferencing Provider (ACP) Functionality Reservation-less bridges Dial-in number provided along with conference ID Operator assisted calls High profile assisted conferencing events Scheduled unattended Ports are reserved for the conference new R2 feature

What Do We Do? Feature SetsOffice Communications Server 2007 R2 Typical Audio Conferencing Provider Typical On-premises solution Paticipant Passcode Leader Passcode (Corporate User PIN) Music on Hold Multiple access numbers with Toll free support One access number supports multiple languages Entry/Exit Announcement (Tone only) Scheduled Meeting Reservation-less Meeting Mute/Un-mute Notification Usage reporting DTMF in-meeting controlOC roster control Recorded nameOC roster / caller ID User Identity User roles only

Microsoft’s Strategy Hit the core scenario Replicate engrained ACP experience No PC required Differentiate with Unified Communications Clear cost savings

Reservationless Comparison Dial-in Conference ID Authenticated user Music on Hold Conference Dial-in Participant pass code Leader pass code Music on Hold Conference Pass code Typical ACP OCS 2007 R2 Music on Hold

Differentiate With UC Ease of use Outlook based scheduling experience Non-UC participants can still join with CWA Simple roster control: drag and drop participants Secure AD authentication Additional security options Multi-modality Seamless escalation to video and desktop sharing Automatic handoff between PC and phone CWA dial out experience …more coming!

Deployment Requirements Standard OCS infrastructure – Front End Servers, AV Conferencing Server, Mediation Server, etc. UCAS with CA and CAS applications Installed and activated by default on each OCS pool CWA server OCS 2007 R2 clients for the best in-meeting experience OCS 2007 clients work as well Additional DID numbers and PSTN trunk capacity for access numbers

Deploy OCS 2007 R2 pool CA and CAS will be installed and activated by default on front end servers Deploy CWA server associate CWA to OCS pools Configure Location Profiles with normalization rules Globally manage access numbers Add access number Specify supported languages Choose CA (pool) to serve the number Assign phone numbers to regions (location profiles) Pool level Personal PIN settings Server Configuration Deployment

Server Configuration Operational Update meeting policies for users Dial-in conferencing capability Pass code requirements MOM monitoring CDR usage reporting

End-user Configuration Outlook-based Authentication method Passcode requirement Region settings Set meeting leaders CWA-based PIN management Access numbers listing

New Concepts Contact Object Based Routing Provides static routing of phone numbers to destinations such as applications An AD contact object is created for each access number with the following information: SIP AOR (Address of Record) Phone number (For RNL) Display phone number Associated pool Application type Application destination (GRUU)

New Concepts Trusted Conferencing Identities OCS allows applications join a conferencing with trusted conferencing identities (services) Trusted conferencing services can send requests to conference without getting challenged A GRUU is associated with each trusted conferencing service, so OCS can route a request to the application’s listening port Trusted conferencing services can: Impersonate a conferencing user (i.e. CA) Act as a “trusted bot” (i.e. CAS)

Conference Directory What is it? A mapping of to Conference IDs to Conference URIs Why do we need it? It is necessary to convert SIP URIs to numeric only ids input from numeric entry systems (such as PSTN) What is its impact? No end user impact Admins need to maintain Conference Directories (Disaster Recovery, Decommissioning Pools, Moving Pools) Related Terms Directory ID: a short numeric ID used to identify a conference directory Conference Resolution: Process of mapping a conf ID to a conference URI

Reporting and CDR Main data points captured for conferences Conference URI Conference start time Conference end time User join time User leave time User join time to conferencing servers (A/V, Data, IM etc) User leave time from conferencing servers Join via PSTN (For A/V Conferences only)

Reports can be filtered by: Dates (Admins can choose the range) Granularity (Hourly, daily, weekly, monthly) Participant Count/ Conference Count/ Minutes Monitoring Server Reports

Performance Counters in SCOM Some key Performance Counters collected by the OCS Management Pack Incomplete Calls per sec, Total Incomplete calls Total calls successfully transferred to conference Current & Total # of Calls on Music on Hold (MoH), Calls Timed out on MoH Total Calls from UC Client Total # of Mute/Un-Mute/Entry/Exit announcements Current & Total # of attendees that have joined conferences, Current & Total # of active personal announcers Current & Total # of conference attendees Performance Counters hold data since the last restart of OCS 2007 R2

Capacity and Scalability Component Supported Performance Conferencing Attendant 450 simultaneous calls (based on a computer with 8 processor cores running at 2.33Ghz, and 4GB of memory) Collocated Access Edge & Web Conferencing Edge Server Access Edge Server: 5,000 client connections Web Conferencing Edge Server: 1,500 client connections Collocated Access Edge, Web Conferencing Edge and A/V Edge Servers (Consolidated Edge Topology) Access Edge Server: 5,000 client connections Web Conferencing Edge Server: 1,000 client connections A/V Edge Server 500 concurrent audio/video sessions

Bringing it together: Scenario Fabrikam 5000 person company 12 offices main office (3500 workers) 1 large branch office (1000 workers) 10 small branch office (50 workers)

Bringing it Together: Deployment

Bringing it Together: Conference Call

Bringing it Together: Management

Bringing it Together: Savings Assuming average worker spends 48 minutes/week on conference calls 6.1 cents/minute 50% of the calls will go over voIP Savings $700k+ /year on ACP cost savings alone ~$8M cumulative cash flow over 3 years
