1 Appendix A UM in Microsoft® Exchange Server 2010

2 Overview Planning the UM Infrastructure Planning the UM Configuration Planning UM Integration with Office Communications Server

3 Lesson 1: Planning the UM Infrastructure UM Architecture and Topology Infrastructure Requirements Business Requirements Planning Considerations Planning Considerations for VoIP Gateways

4 UM Architecture and Topology VoIP protocols- such as SIP and RTP-are between Unified Messaging and IP PBX or IP gateways Other protocols are between server roles Directory server Hub Transport server Mailbox server Client Access server Unified Messaging server Outlook Web Access Internet Microsoft Exchange ActiveSync UM IP Gateway IP PBX PBX PSTN Internal phone External phone Internal phone Internal phone Firewall SMTP MAPI RPC HTTPS VoIP RPC/HTTPS TDM LDAP Forest Site

5 Infrastructure Requirements Server roles Mailbox server Hub Transport server Client Access server Unified Messaging server Other infrastructure requirements VoIP phone AD DS PBX Unified Messaging IP gateway

6 Business Requirements Number of supported users Phone and voice mail users Storage requirements for users Voice mail codec Number of simultaneous users

7 Planning Considerations Telephony network and current voice mail system Current data network design AD DS environment IP/VoIP gateways, telephony equipment, and Unified Messaging servers placement PBXs are networked, centralized, or located in multiple locations Place PBXs physically close to IP gateways IP gateway and Unified Messaging placement Exchange Server roles and Unified Messaging Servers WAN termination Codec

8 Planning Considerations for VoIP Gateways Supported IP/VoIP gateways Two configurations for IP/VoIP gateway devices: IT/PBX: A single hardware device Legacy PBX and an IP/VoIP gateway: Two separate hardware devices Multiple IP gateways Multiple locations

9 Lesson 2: Planning the UM Configuration Hardware Infrastructure Requirements UM Dial Plan Object UM Hunt Group Object UM Server Object UM Mailbox Policy Object UM Clients Process for Deploying UM

10 Hardware Infrastructure Requirements Processor Minimum: 2 processor cores Recommended: 8 processor cores Maximum: 12 processor cores Memory Minimum: 4 GB Recommended: 2 GB per processor core Storage Number of users Number of language packs

11 UM Dial Plan Object A dial plan object: Is an Active Directory container object that logically represents sets or groupings of PBXs that share common user extension numbers Represents the scope of a voice mail system that Unified Messaging is replacing, generally A dial plan: User can reach all others using a fixed length extension number Extension is unique May consist of feature transparent PBX networks Plus the extension number uniquely identifies each Unified Messaging user A dial plan object: Is an Active Directory container object that logically represents sets or groupings of PBXs that share common user extension numbers Generally represents the scope of a voice mail system that Unified Messaging is replacing A dial plan: User can reach all others using a fixed length extension number Extension is unique May consist of feature-transparent PBX networks Extension number uniquely identifies each Unified Messaging user

12 UM Hunt Group Object A hunt group: Is a group of PBX or IP/PBX resources or extension numbers, that represent a collection of like endpoints Is used to distribute calls efficiently into or out of a given business unit Is accessed by using a pilot number Hunt group objects: Represent a hunt group configured at the PBX, to direct calls to a VoIP gateway Are contained within a Unified Messaging IP gateway object One or more hunt groups can be associated with a Unified Messaging IP gateway

13 UM Server Object An administrable object used for controlling Unified Messaging properties on an Exchange Server 2010 server running the Unified Messaging server role Performs directory lookups in AD DS in these scenarios: To locate the Mailbox server that hosts the user mailbox To locate user’s prerecorded, spoken names from AD DS To locate subscriber extensions and other attributes A default deployment of a Unified Messaging server can support up to 100 concurrent voice mail connections

14 UM Mailbox Policy Object Unified Messaging mailbox policies are conceptually similar to traditional voice mail Classes of Service Unified Messaging mailbox policy properties can include: Dial plan (required) Maximum greeting length Number of unsuccessful login attempts before password reset Minimum digits required in a PIN Number of days until a new PIN is required Number of previous passwords disallowed Calling restrictions

15 UM Clients Unified Messaging clients include: Office Outlook 2007 Outlook Web Access Windows® Mobile and Microsoft Exchange ActiveSync Outlook Voice Access (internal and external phone)

16 Process for Deploying UM 1.Create a Dial Plan object 2.Create a Unified Messaging IP gateway object, and associate it with the Dial Plan object (optional) 3.Create a Hunt Group object, and associate it with a Unified Messaging IP gateway object (optional) 4.Enable users, and associate them with a mailbox policy

17 Lesson 3: Planning the UM Integration with Office Communications Server Office Communications Server 2007 R2 Features Benefits of UM Integration with Office Communications Server 2007 Planning the UM and Office Communications Server Integration

18 Office Communications Server 2007 R2 Features Office Communications Server 2007 provides: Instant messaging Presence information Web conferencing VoIP Unified Messaging can be integrated with Office Communications Server 2007 to provide access to messaging and voice functionality using both messaging and Office Communications Server clients

19 Benefits of UM Integration with Office Communications Server 2007 Integration provides these additional benefits: Dial plans enable an Office Communications Server 2007 user to call another without dialing that user High-fidelity voice messages Access to Outlook Voice Access from Office Communicator 2007 without requiring a PIN Office Communicator 2007 clients can associate subjects and priorities to voice messages Missed call e-mail notification messages using Message Waiting Indicator Messages received within the Office Communications Server 2007 environment cannot be forwarded outside the Office Communications Server 2007 environment to preserve the security and privacy of voice mail

20 Planning the UM and Office Communications Server Integration Integration planning considerations Bandwidth Dial plans Number of users IP gateway placement Fault tolerance
