6. Types of PBXs PBX Type Description Analog Sends voice and signaling information as actual analog sounds Digital Encodes analog sound into a digital format IP PBX Uses packet switching to carry voice conversations over data networks Acts as a gateway between telephone and data networks Hybrid PBX Provides both digital and IP PBX capabilities

7. What Is a VoIP Gateway? VoIP gateway converts traditional circuit-switching protocols into packet-switched protocols Circuit-switched networks use a dedicated connection between two network devices, such as phones Packet-switched networks divide each data message into packets that are sent to their destination and reassembled VoIP enables IP-based networks as the transmission medium for telephone calls

8. Unified Messaging Protocols Protocol Description Session Initiation Protocol (SIP) Signaling protocol used to create, manipulate, and disconnect interactive communication sessions on an IP network Real-Time Transport Protocol (RTP) Protocol used to transmit streaming voice or video data over an IP network Unified Messaging Web Services IP-based network communication between a client, the Unified Messaging server, the Client Access server, and computers running other Exchange Server 2010 server roles

International Requirements for Unified Messaging Copies the language prompts that will be used to configure Unified Messaging dial plans and auto attendants Allows the Text-To-Speech (TTS) engine to read messages when Outlook Voice Access users access their Inbox. Enables Automated Speech Recognition (ASR) for speech-enabled Unified Messaging dial plans and auto attendants for the language installed. Unified Messaging provides language packs to satisfy international requirements for Unified Messaging Available language packs include: German, Spanish, French, Japanese, and more A language pack adds the following: Copies the language prompts used to configure Unified Messaging dial plans and auto attendants Allows the Text-To-Speech (TTS) engine to read messages when Outlook Voice Access users access their inboxes Enables Automated Speech Recognition (ASR) for speech-enabled Unified Messaging dial plans and auto attendants

18. Lesson 3: Configuring Unified Messaging Process for Installing Unified Messaging What Is a Unified Messaging Dial Plan? What Is a Unified Messaging IP Gateway? What Is a Unified Messaging Hunt Group? What Is a Unified Messaging Mailbox Policy? What Is a Unified Messaging Auto Attendant? Rules for Call Answering

19. Process for Installing Unified Messaging Create a Unified Messaging hunt group 4 Install the Unified Messaging server role 1 Create a Unified Messaging IP gateway 3 Configure a Unified Messaging mailbox policy 5 Enable mailboxes for Unified Messaging 6 Create a Unified Messaging dial plan 2 Create an auto attendant 7

20. What Is a Unified Messaging Dial Plan? Unified Messaging dial plans: Are used to link user mailboxes to their extension numbers Are used to configure default settings such as greetings, dial codes, and languages Are managed using the Exchange Management Shell or the Exchange Management Console You need at least one Unified Messaging dial plan, and that dial plan requires a Unified Messaging server and an associated Unified Messaging IP gateway

21. What Is a Unified Messaging IP Gateway? Unified Messaging IP gateways: Are managed using the Exchange Management Shell or the Exchange Management Console Can be disabled to drop all calls or stop receiving new calls A Unified Messaging IP gateway is an Active Directory container object that logically represents a physical VoIP gateway or IP-PBX device

22. What Is a Unified Messaging Hunt Group? Unified Messaging hunt groups: Are logical representations of an existing PBX hunt group to link IP gateways and dial plans Are used to locate the PBX hunt group Are managed using the Exchange Management Shell or the Exchange Management Console

23. What Is a Unified Messaging Mailbox Policy? You can specify: Dial plan Maximum greeting length Login attempts before the password is reset PIN restrictions Restrictions on international calling Protected voice-mail settings Unified Messaging mailbox policies apply configuration settings for Unified Messaging–enabled users

24. What Is a Unified Messaging Auto Attendant? Auto attendants provide: Corporate or informational greetings Custom corporate menus A directory search function The ability to connect to the telephone of organizational members Auto attendants let callers navigate through a voice-menu system to locate, and place calls to, users in the organization

25. Rules for Call Answering Call answering rules provide users with more control over their personal call answering system with features such as special greetings by contact or time of day Call answering rules include: Conditions: If it evaluates to true, then run A greeting and menu: Collect caller’s menu selection Actions: Transfer, “Find me,” or leave message Configure call answering rules in Outlook Web App or Outlook 2010
