Add a SIP Address for a UM-Enabled User

  • Article

Applies to: Exchange Server 2010

When you enable a user for Unified Messaging (UM), you must define at least one extension number that's used by Unified Messaging when voice mail is submitted to the user's Microsoft Exchange Server 2010 mailbox. But you have the option to add a Session Initiation Protocol (SIP) address for a user if the user is associated with a SIP Uniform Resource Identifier (URI) dial plan. After you enable the user for Unified Messaging, you can add SIP addresses to the user's mailbox by configuring the Exchange Unified Messaging proxy address (EUM proxy address) on the user's mailbox.

  • The SIP address that's assigned to the UM user is valid according to the UM dial plan that's associated with the UM-enabled user.
