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 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. 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 Unified.

Availability through Redundancy PBX routes calls to available Vo. IP 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 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 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 10 K ORG UM can cover 10 K 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 Unified. Simplified.

UM Changes in E 2 K 7 SP 1 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 Vo. IP Performance Improvements Unified. Simplified.

UM & OC/OCS Better Together Unified. Simplified.

Fax Tone Detection by UM Server In E 2 K 7 RTM, UM relied on IP gateway GW detects fax tone GW notifies UM server (RFC 2833/CNG) UM Server renegotiates media as fax (T. 38) Did not work with IP PBXs (Cisco, Avaya…) In SP 1, UM can detect fax tone itself OFF by default Must configure on each UM Server Enable. Inband. Fax. Detection (globcfg. xml) Unified. Simplified.

Support for Secure RTP (SRTP) RTM: UM signaling could be secured (TCP, RTP) SIPSecured (MTLS, RTP) Dial. Plan. Vo. IPSecurity = None Dial. Plan. Vo. IPSecurity = SP 1: signaling and media can be secured Dial. Plan. Vo. IPSecurity = Secured Unified. Simplified. (MTLS, SRTP)

Quality of Service (Qo. S) Mark (Vo. IP) audio for expedited routing RTC media “under” UM will support Qo. S Differentiated Services Code Point (DSCP) Codepoint for UM audio packets Default 101000 (0 x 40); Group Policy control Requires Windows Qo. S Packet Scheduler In Windows Server 2008 Manual install for W 2 K 3 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 Codec RTM SP 1 (W 2 K 3) SP 1 (W 2 K 8) WMA 60 70 80 GSM 75 100+ Unified.
