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
