Exchange Server 2010: Unifying the Messaging Infrastructure

Email | Print

Unified messaging combines voice and e-mails into a single infrastructure by putting voice and e-mail messages into one mailbox. The unification is carried further by making it possible to access the mailbox from different devices, including Outlook Voice Access, telephone, mobile phone or computer.

To deliver this functionality the Unified Messaging server (UMS) must be deployed in Exchange Server 2010. The UMS role can be installed on a computer that has no other server roles, or it can be installed along with other roles. The installation can be done using the setup wizard or command prompt.

Installing the UMS alone is not enough for the server to process incoming calls. See http://technet.microsoft.com/en-us/library/dd335104.aspx for the steps needed to deploy a unified messaging environment. The steps include providing PBX lines and related tasks, for example.

After the UMS role is created, a UM Dial Plan must be created to establish a link from the telephone extension to the UM enabled mailbox. The Dial Plan can be created using the Exchange Management Console or PowerShell script.

A UM IP Gateway is created to enable Unified Messaging servers to connect to a new IP gateway or an IP Private Branch eXchange (PBX). The gateway provides compatibility between the telephony network and the IP or packet switched network.

Exchange Server 2010 can use the Microsoft Communication Server 2007 platform to unify instant messaging, audio/video conferencing and enhanced presence with e-email. The enhanced presence notifications indicating the availability of a contact will also be available across a variety of applications. Users can also switch from one mode of communication to another as needed.

The Communications Server and Exchange Server 2010 can be used together to create a great communication scenario that includes:

  • Call Notification: If a call is unanswered, the called person receives an email indicating that the caller called.
  • Voice Mail Messages: When a call is unanswered, the caller can be invited to leave a voice mail message
  • Subscriber Access: A subscriber can call an access number and listen to e-mail and voice messages in the mailbox, and use the callback option to return a call from a caller.

Integrating Exchange Server 2010 and the Communications Server is discussed at http://technet.microsoft.com/en-us/library/bb676499.aspx.

Specific actions in addition to deploying the UMS role are needed to create the kind of unified communications infrastructure outlined above.
