  2. Session Objectives After this session, you will… Understand the value of Exchange Server 2007 Unified Messaging Learn about new features in Service Pack 1 Understand the Microsoft Exchange Server UM Architecture Understand the setup and basic administration process

  3. Why We Need Unified MessagingProblems of disunity • Voice and e-mail as separate inboxes • Different servers, access mechanisms • Desktop software (e-mail) • Phone (voice mail) • Fax messages • Stand-alone fax machines • Users and administrators must manage their messages from multiple locationswith different tools “With Exchange Server 2007, we look forward to being able to communicate better…Will this technology help us sell more golf clubs? In this case, yes, we believe that better communication will help us sell more golf clubs.” —Eric Hart, End-User Computing Manager, PING Inc.

  4. Exchange Server Unified MessagingDelivering on a clear and simple vision • Convenient, integrated access to your vital business communications • Reducing costs, increasing operational efficiency by consolidating infrastructure, training • Unified store, transport, directory • Increasing client reach to the telephone • “Anywhere access” to your messages, calendar, contacts “Having anywhere access to e-mail and voice mail is going to be a huge benefit... People can access information and interact with it using a variety of devices, at work, at home, and on the road; and all of this translates directly into productivity.” —Steven Presley, Senior IT Engineer for Messaging, QUALCOMM

  5. VoIP protocols (SIP, RTP, T.38) between UM and IP PBX/gateway Works with many varieties of PBX Well suited to site consolidation Scalable, reliable Exchange Server UM Architecture

  6. Setup and Basic Administration • Preparation • Install Exchange Server 2007 •  Mailbox •  Hub Transport •  Client Access •  Unified Messaging • Create mailboxes • Set up IP gateway • Demo • Configure UM • Create UM Dial Plan • Create UM IP Gateway • Join UM Server to Dial Plan • Call UM • “Welcome. You are connected to Microsoft Exchange…”

  7. demo UM Setup and Basic Administration

  8. Preparing the System for Callers • Enable Users for UM • Exchange Management Console • Exchange Management Shell • Dial Plan • Log in to Outlook Voice Access • New User Dialog (Record Name, Greeting) • Call UM-enabled user • Hear greeting • Record voice message • Receive fax message • Special storage quota

  9. demo Preparing Exchange UM for Callers

  10. UM Automated Attendants • Call Answering is great, but: • What if caller doesn’t know the user’s phone number? • What if the user doesn’t have a direct-dial number? • Automated Attendant • Create New Auto Attendant (Speech Enabled) • Customise Welcome Greeting • Configure Business Hours, Time Zone • Create Menu, Add Menu Options • Use menu option • Telephone keypad • Speak the option name • Transfer to user by speaking their name

  11. demo UM Automated Attendants

  12. UM in Outlook 2007 and OWA • Custom Rendering • Voice messages • Play (multimedia) • Play on phone • Fax messages • Voice mail options • Reset PIN • E-mail folder • Missed call notifications

  13. demo UM in Outlook Web Access 2007

  14. Outlook Voice Access • Phone interface to Exchange Server 2007 • Speech enabled (English) or Touch Tone • Voice • Play, forward, delete, call sender, etc. • E-mail messages • Language detection, play, forward, delete, find, hide etc. • Calendar • Accept invitation, play details, clear, etc. • Personal contacts, directory • Call (office/cell/home), send a message

  15. demo Outlook Voice Access

  16. UM Configuration and Site Topology • UM Servers can handle calls for multiple UM Dial Plans • UM Server • UM Dial Plan • UM Auto Attendant • UM Mailbox Policy • UM IP Gateway • UM Hunt Group • UM Mailbox • = UM-Enabled User

  17. UM Mailbox Policy • Configure properties for many UM-enabled users through a single object

  18. UM Dialing Rules • Dial Plan defines groups of number patterns, and which of them may be dialed • Mailbox Policy references allowed group(s) and determines who may dial them • Auto Attendants may also reference allowed groups

  19. demo UM Mailbox Policy and Dialing Rules

  20. Monitoring • Based on the Test-UMConnectivitycmdlet • Local (on UM Server) • Test-UMConnectivity • Remote (via gateway/PBX or IP-PBX) • Test-UMConnectivity –Phone 50000 –UMIPGatewayMyGW • End to end (accesses mailbox) • Test-UMConnectivity –TUILogon $true –Phone 56789 −PIN 672316 –UMDialPlanMyDP • UM rules in MOM Pack can build reports

  21. Availability through Redundancy • PBX routes calls to available VoIP gateways • VoIP gateways route calls to available UM servers • UM service redirects calls to worker process • UM accommodates outage in mailbox, transport, DC • Maintains service if possible Service Worker process

  22. Scalability • Provide capacity for concurrent calls • PBX • Provision circuit switched channels • Organise into hunt groups for IP gateways • IP Gateways • Add for capacity, redundancy • UM Servers • Add for capacity, redundancy • ~10,000 UM enabled users each • May be less if access is heavy Capacity required to fix probability (1%, 5%) of caller not being connected to UM in busiest hour (14% calls) of day for different patterns of UM usage

  23. Why UM Scales Better than VM • Typical MORG/LORG voice mail systems have 16 ports (or fewer) • Covers up to ~1000 voice mailboxes • Approx. 10× systems (160 ports) for 10K ORG • UM can cover 10K users with ~80 ports • Voice messages in Outlook (no call required) • Consolidation of spare capacity • 2 UM servers can replace 16 VM servers • (1 + 1) configuration for redundancy • Operating costs greatly reduced

  24. UM Changes in E2K7 SP1 • Support for Office Communicator 2007 and Office Communications Server 2007 • Support for Windows Server 2008 • Fax tone detection by UM Server • Support for SRTP • Support for quality of service for VoIP • Performance Improvements

  25. UM & OC/OCS Better Together

  26. Fax Tone Detection by UM Server • In E2K7 RTM, UM relied on IP gateway • GW detects fax tone • GW notifies UM server (RFC2833/CNG) • UM Server renegotiates media as fax (T.38) • Did not work with IP PBXs (Cisco, Avaya…) • In SP1, UM can detect fax tone itself • OFF by default • Must configure on each UM Server • EnableInbandFaxDetection (globcfg.xml)

  27. Support for Secure RTP (SRTP) • RTM: UM signaling could be secured • DialPlan.VoIPSecurity = None (TCP, RTP) • DialPlan.VoIPSecurity = SIPSecured (MTLS, RTP) • SP1: signaling and media can be secured • DialPlan.VoIPSecurity = Secured (MTLS, SRTP)

  28. Quality of Service (QoS) • Mark (VoIP) audio for expedited routing • RTC media “under” UM will support QoS • Differentiated Services Code Point (DSCP) • Codepoint for UM audio packets • Default 101000 (0x40); Group Policy control • Requires Windows QoS Packet Scheduler • In Windows Server 2008 • Manual install for W2K3

  29. UM Performance Improvements • Number of concurrent calls is the metric • Depends on codec used to record messages • 2 × 2-core 4 GHz Xeon proc, 4 GB RAM • Tested with Windows Server 2003 and 2008 • G.711 wire codec, TCP, RTP • G.723.1, TLS, SRTP give similar figures

  30. Compliance, Discoverability • Some confusion/concern about voice mail retention • Legal opinion (Covington & Burling LLP) • http://www.microsoft.com/exchange/evaluation/unifiedmessaging/dataretentionwp.mspx • “…no aspect of Exchange alters, by increasing or decreasing, the record retention obligations of … organisations [using it] in the U.S. or E.U.” • Exchange can help the customer • Many features to implement compliance policy • Easier to locate and sort voice mail, if needed
