3. Unified. Simplified. 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

4. Unified. Simplified. Why We Need Unified Messaging Problems 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 locations with 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.

5. Unified. Simplified. Exchange Server Unified Messaging Delivering 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

6. Unified. Simplified. Exchange Server UM Architecture 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

9. Unified. Simplified. 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

10. Unified. Simplified. Preparing Exchange UM for Callers

11. Unified. Simplified. 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

12. Unified. Simplified. UM Automated Attendants

13. Unified. Simplified. 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

14. Unified. Simplified. UM in Outlook Web Access 2007

15. Unified. Simplified. 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

16. Unified. Simplified. Outlook Voice Access

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

18. Unified. Simplified. UM Mailbox Policy Configure properties for many UM-enabled users through a single object PropertyDescription UMDialPlan Dial plan to which the user belongs MinPINLength Minimum number of digits allowed in user’s PIN PINLifetime Maximum time between PIN changes LogonFailuresBeforePINReset Consecutive TUI logon failures triggering PIN reset VoiceMailText Inserted at end of each voice mail message body AllowedInCountryOrRegionGroups Determines which dialing rules are allowed AllowedInternationalGroups Determines which dialing rules are allowed … …

19. Unified. Simplified. 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

20. Unified. Simplified. UM Mailbox Policy and Dialing Rules

21. Unified. Simplified. Monitoring Based on the Test-UMConnectivity cmdlet Local (on UM Server) Test-UMConnectivity Remote (via gateway/PBX or IP-PBX) Test-UMConnectivity –Phone 50000 –UMIPGateway MyGW End to end (accesses mailbox) Test-UMConnectivity –TUILogon $true –Phone 56789 −PIN 672316 –UMDialPlan MyDP UM rules in MOM Pack can build reports

22. Unified. Simplified. 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

23. Unified. Simplified. 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

24. Unified. Simplified. 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

25. Unified. Simplified. 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

26. Unified. Simplified. UM & OC/OCS Better Together

27. Unified. Simplified. 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 )

28. Unified. Simplified. 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)

29. Unified. Simplified. 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

30. Unified. Simplified. 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 CodecRTMSP1 (W2K3)SP1 (W2K8) WMA60 70 80 GSM75100+

31. Unified. Simplified. 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
