How to Add, Remove, or Modify a SIP Address for a UM-Enabled User

 

Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1, Exchange Server 2007

Topic Last Modified: 2007-08-22

This topic explains how to add, remove, or modify Session Initiation Protocol (SIP) addresses for a recipient who is enabled for Microsoft Exchange Server 2007 Unified Messaging (UM). If you have the original release (RTM) version of Exchange 2007 installed, use the Exchange Management Shell to perform this procedure. If you have Exchange Server 2007 Service Pack 1 (SP1) installed, you can make these changes by using either the Exchange Management Shell or the Exchange Management Console.

noteNote:
In the RTM version, you must use the Set-Mailbox cmdlet to add, remove, or modify extension numbers.

When you enable a user for Unified Messaging, you must define at least one extension number that will be used by Unified Messaging when voice mail is submitted to the user's Exchange 2007 mailbox. However, you will have the option to add a SIP address for a user if the user is associated with a SIP URI dial plan. After you have enabled the user for Unified Messaging, you can add SIP addresses to the user's mailbox, or modify or remove them by configuring the Exchange Unified Messaging proxy address (EUM proxy address) on the user's mailbox.

The mailbox of a UM-enabled user can be associated with only one UM dial plan. However, the mailbox of a UM-enabled user can be assigned the following:

  • A single extension number, SIP address, or E.164 address on a single dial plan.

  • Multiple extension numbers, SIP addresses, or E.164 addresses on a single dial plan.

  • Multiple extension numbers, SIP addresses, or E.164 addresses on two separate dial plans.

For example, a UM-enabled user travels frequently from New York to Tokyo. The user's mailbox is associated with the New York dial plan and a single SIP address is configured on the user's mailbox. A second SIP address is configured on the user's mailbox for the Tokyo dial plan. When callers dial either extension number and leave a voice message for the user, the voice message will be delivered to the same UM-enabled mailbox.

You can also add, remove, and modify extension numbers and E.164 addresses. For more information about how to add, remove, and modify extension numbers and E.164 addresses, see the following topics:

To perform the following procedures, the account you use must be delegated the Exchange Recipient Administrator role.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

Also, before you perform these procedures, confirm the following:

  • The existing Exchange recipient has an Exchange 2007 mailbox.

  • The existing Exchange 2007 recipient is enabled for Unified Messaging.

  • A SIP URI dial plan has been created.

  • A UM mailbox policy has been created.

  • The SIP address that will be assigned to the UM user is valid.

  1. In the console tree, expand Recipient Configuration, and then click Mailbox.

  2. In the result pane, select the mailbox for which you want to add a new e-mail address.

  3. In the action pane, under the mailbox name, click Properties.

  4. In <Mailbox User> Properties, click the E-Mail Addresses tab.

  5. To create a new e-mail address, under E-mail Addresses, perform one of the following tasks:

    • To add a new EUM proxy address, click the drop-down arrow next to Add, and then click EUM Address. In UM Address (Extension), in the Address/Extension box, type the SIP address. In the Dial plan (Phone context) box, click Browse to locate the dial plan for the user.

    • To modify an existing EUM proxy address, select the appropriate EUM proxy address, and then click Edit. In UM Address (Extension), in the Address/Extension box, type the new SIP address. In the Dial plan (Phone context) box, click Browse to locate a new dial plan for the user.

    • To remove an existing EUM proxy address, click Remove icon.

  6. Click Apply, and then click OK.

  • To add a SIP address for a user, run the following command:

    $mbx = Get-Mailbox tony.smith
    $mbx.EmailAddresses +="eum:tony.smith@contoso.com; MyDialPlan.contoso.com"
    $mbx | set-mailbox
    
  • To modify a SIP address for a user, run the following command:

    $mbx = Get-Mailbox tony.smith
    $mbx.EmailAddresses.Item(1) ="eum:tsmith@contoso.com;phone-context=MyDialPlan.contoso.com"
    $mbx | set-mailbox
    
    noteNote:
    You must determine the position of the EUM proxy address that you want to modify. To determine the position of the EUM proxy address, use the $mbx.EmailAddresses command. The first proxy address in the list will be 0.
  • To remove a SIP address for a user, run the following command:

    $mbx = Get-Mailbox tony.smith
    $mbx.EmailAddresses -="eum:tony.smith@contoso.com; MyDialPlan.contoso.com"
    $mbx | set-mailbox
    

For more information about syntax and parameters, see Set-Mailbox or Get-Mailbox.

  • Run the following command:

    Enable-UMMailbox -Identity tonysmith@contoso.com -UMMailboxPolicy MyDomainUMPolicy -SIPResourceIdentifier: +14255550105
    
    noteNote:
    In the release to manufacturing (RTM) version of Exchange 2007, to configure a SIP address for a user, you must use the Enable-UMMailbox cmdlet. You cannot use the Set-Mailbox cmdlet to add, remove, or modify SIP addresses.

For more information about syntax and parameters, see Enable-UMMailbox (RTM).
