  • Automatic Speech Recognition (ASR) that is used with the Voice User Interface (VUI) in Outlook Voice Access
  • The Text-to-Speech (TTS) engine that reads e-mail, voice mail, and calendar items and plays the menu prompts for callers

4. What is Unified Messaging work Process?

A Unified Messaging worker process is a process that is created during the startup of the Microsoft Exchange Unified Messaging service. UM worker processes interact with all incoming and outgoing requests that have been received by the Microsoft Exchange Unified Messaging service.

The Unified Messaging Worker Process Manager is also a component of the Microsoft Exchange Unified Messaging service. The UM Worker Process Manager handles the creation and monitoring of all the UM worker processes that are created.

5. What are the Unified Messaging Server consolidations?

To consolidate unified messaging server, place all the Unified Messaging Server Role in a central location and place IP gateways in branch offices.

6. How e-mail, voice and fax services are managed in UM?

Unified messaging puts all a UM-enabled user’s e-mail, voice, and fax messages into their Exchange 2007 mailbox and that can be accessed from a variety of devices.

  6. Voice mail message delivered to users mailbox

12. What is PBX and IP gateway?

PBX – Private Branch Exchange

PBX, sometimes known as a telephone switch or telephone switching device, is a device that connects office telephones in a business to the public telephone network. The central functions of a PBX are to route incoming calls to the appropriate extension in an office, and to share telephone lines between extensions. Users of the PBX share a certain number of outside lines for making telephone calls external to the PBX.

IP Gateway

IP gateway devices are integral to deploying Exchange 2007 Unified Messaging in your organization. There are two types of IP gateway devices that you can use with Exchange 2007 Unified Messaging: an IP PBX and IP gateway. Both types of devices can exist in a single organization. However, you must configure each IP gateway or IP PBX device correctly to successfully deploy Exchange 2007 Unified Messaging.

The IP PBX or the IP gateway devices in your organization are the intermediary components between your organization’s telephony network and your organization’s data network. IP PBXs and IP gateways act as a “translator” and are used to convert the circuit-switched protocols that are found in your telephony network to the packet-switched protocol, IP, that is found in your data network.

13. What are the Active Directory UM objects?

Following are the Active Directory UM objects

  • UM Auto attend
  • UM mailbox policy
  • UM IP gateways
  • UM hunt group

14. Explain Outlook Voice Access?

  1. 1. UM-enabled user dials the subscriber access number configured on a dial plan
  2. 2. UM server associated with the dial plan checks active directory for address and access information

16. What are the unified messaging Mailbox policies?

UM mailbox policies are required when you enable users for Exchange 2007 Unified Messaging. They are useful for applying and standardizing Unified Messaging configuration settings for UM-enabled users. You create UM mailbox policies to apply a common set of policies or security settings to a collection of UM-enabled mailboxes.

  • PIN policies
  • Dialing restrictions
  • Other general UM mailbox policy properties – increase the level of PIN security by reducing the maximum number of logon failures

17. what is UM hunt group?

A hunt group describes a set of PBX or IP PBX resources or extension numbers that are shared by users. Hunt groups are used to efficiently distribute calls into or out of a given business unit. For example, a PBX or IP PBX might be configured to have 10 extension numbers for the sales department. The 10 sales extension numbers would be configured as one hunt group. In a PBX or IP PBX, hunt groups are used to efficiently locate an open line, extension, or channel when an incoming call is received

18. what is UM IP Gateway?

A UM IP Gateway object is a container object that logically represents a physical IP gateway hardware device, IP-PBX, or other SIP server that can interoperate with Exchange Unified Messaging. Before the IP gateway can be used to process Unified Messaging calls, it must be represented by an object in Active Directory.
