2. Adam Jacobs Lync MVP @adamjacobs http://imaucblog.com adam@imaucblog.com Introduction to Lync Server

3. Agenda What is Lync Server? History Industry recognition Implementation approaches Technical differentiators from Office Communications Server (OCS) Setup and deployment Introducing: The Central Management Store (CMS) Call Admission Control (CAC) Media Bypass Futures

4. What is Lync Server?

5. Lync not LINQ The new name for OCS An IP-PBX or traditional PBX replacement A new breed of software-based telephony Fully immersed within your PC (or Mac) desktop user experience – Office, SharePoint & Lync Client The heart of Microsoft’s UC stack

6. Authentication Administration Storage Compliance Authentication Administration Storage Compliance Audio Conferencing E-mail and Calendaring E-mail and Calendaring Web Conferencing Web Conferencing Telephony Video Conferencing Video Conferencing Voice Mail Instant Messaging (IM) Communications Today Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Authentication Administration Storage Telephony and Voice Mail Telephony and Voice Mail Instant Messaging E-mail and Calendaring Unified Conferencing: Audio, Video, Web Future of Communications

7. Then… Office Communications Server Microsoft® A PBX companion – high level deliverables include: Voice calls via existing handsets (RCC) and Communicator/“Optimised Devices” (EV) Video calls IM and presence Mobility (including IM, presence and single-number reach) *Office Communications 2007 R2 Collaboration (desktop/file sharing, group chat and *dial-in conferencing)

8. And now… A PBX replacement – via added functionality: Enhanced resilience - without the need for h/w load balancing (web workloads still require HLBs) Survivable Branch Appliance – a purpose-built appliance for branch deployments Call Admission Control (CAC) – for the prevention of VoIP over subscription Enhanced 9-1-1 (NA only) – CU1 delivers location functionality Superior conferencing - voice announcements and an integrated client! (no Live Meeting client or Outlook Conferencing add-in) Microsoft Lync ® TM

9. Industry recognition “Magic Quadrant for Unified Communications,” July 28, 2010. “OCS…is certainly going to shake up the market.” 36% companies surveyed are already using OCS as UC client, more than IBM, Cisco and Public IM clients. “If you didn’t think Microsoft was serious about voice communications before, you better believe it now.”

10. Implementation approaches Existing PBX with Remote Call Control (RCC) *Unified Communications Open Interoperability Program - herehere Hybrid - existing PBX with RCC and Enterprise Voice (EV) Full EV – no PBX Leverage existing PBX investment and introduce Communicator concepts via RCC Identify PBX integration opportunities – software upgrades and/or a vendor application gateway. Consult your PBX vendor and visit the *UCOIP Introduce Conferencing functionality and cut existing costs (measure telephony capacity first) – my workplace saved £60k per annum! Consult your PBX vendor and visit the *UCOIP, identify integration opportunities. Alternatively you can deploy a side-by-side voice gateway Initially choose mix legacy, RCC and EV for agile workers (project teams, senior executives and IT) Telephony growth supported by EV with Lync chosen as standard for strategic replacement For greenfield deployments a voice gateway could be used, consult the *UCOIP for supported hardware Alternatively it could be the right time to replace your existing PBX for Lync – how many times has this asset been written off?

11. Technical differentiators from OCS

12. Key Lync Roles and Servers *Central Management Store (CMS) covered in subsequent slide *Introduced with Lync Front End Server Handles authentication/registration, address book, IM, Conferencing & Response Groups Back End Server Lync database A/V Conferencing Server as the name suggests (can be collocated with Front End server or deployed separately) Edge Server used for external Communication & Collaboration (without the need for VPN) Mediation Server translates signalling and media (where bypass is not used) and routes to PSTN via gateway, IP-PBX or SIP trunk Monitoring Server collects call quality and CDR related information Archiving Server collects IM and Meeting content Director Internally, routes clients to corresponding home server Externally, reverse proxies authentication requests *Survivable Branch Appliance (SBA) a purpose-built Lync appliance, typically utilised for branch deployment

13. Setup and deployment changes worth mentioning Planning Tool Export to Topology Builder (.tbxml) Topology Builder Tool used for.tbxml import, topology setup, modification and validation prior to deploying first server and publishing within the Central Management Store (CMS) Mediation role can now be collocated with front end role = minus 1 server Essentially one Standard Edition Server could support Enterprise Voice, IM, Presence and Conferencing for up to 5000 users! For more information on planning and designing your Lync topology, I’d suggest you watch Lync Server Planning Tool: Design a Site and Create a Topology via TechNet NextHop (see resources slide)

14. Central Management Store (CMS) Replaces Active Directory for most configuration storage (phone numbers still held within AD) The CMS data is held within a SQL database Centralises the administration of all Lync Server roles (including Edge servers) There is a minimum requirement of 2 x CMS databases - 1 x master (RTC) and 1 x replica (RTCLOCAL) RTC and RTCLOCAL databases are replicated Resilient architecture – Front End Server CMS (replica) will continue to function where connectivity is lost to the master

15. Call Admission Control (CAC) Put simply CAC is the bandwidth management service built into Lync Server CAC bandwidth policies can be set to control Audio - max bandwidth (kbps) assigned for all/individual sessions Video - max bandwidth (kbps) assigned for all/individual sessions Policies are applied between sites, where multiple network subnets can be associated Alternate routes can be utilised where over-subscription occurs, i.e. when local ISDN is at capacity then a route to PSTN over an Internet based SIP trunk could apply

16. Media Bypass Media bypass reduces the load on your Mediation servers (allowing support for up to 5000 users, where Front End and Mediation roles are collocated) This is achieved by negating the need for transcoding between the Lync client or phone and the voice gateway In this scenario the G.711 voice codec is used, instead of RTAudio Recommended gateway vendors include AudioCodes, Dialogic, NET and Ferrari

17. Futures

18. Lync Mobile Mobile clients are expected for: *iPhone aka “iLync” *Windows Phone 7 BlackBerry – now available BES v.5.0 SP3 Nokia Android *NB Functionality will include: One-click to join conference Single number reach ETA late 2011

19. Lync for XBOX “videoKINECT” ETA late 2011

20. Lync Server + Skype = ? Jamie Stark Lync Server Product Manager
