Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

 

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

This topic explains how to use the Performance console and the Exchange Management Shell to view the number of active Unified Messaging (UM) calls that are being processed. You can view the number of active calls for a UM dial plan, a Unified Messaging server, or all calls for a UM IP gateway. If you use the Get-UMActiveCalls cmdlet to view the number of active calls for dial plans or IP gateways, the cmdlet uses the Active Directory directory service to determine which Unified Messaging servers must be contacted.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group for the target server.

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

Procedure

To use the Performance console to view the number of active calls

  1. Click Start, click Programs, click Administrative Tools, and then click Performance.

  2. In the Performance console, right-click in the details pane, and then select Add Counters from the menu. You can also press CTRL+I to open the Add Counters window.

  3. In the Add Counters window, in the Performance object list, select MSExchangeUMGeneral.

  4. In Select Counters from list, select Current Calls, click Add, and then click Close.

  5. In the Performance console, in the details pane, select the Current Calls counter to display the number of current calls.

To use the Exchange Management Shell to view the number of active calls for a UM server

  • Run the following command:

    Get-UMActiveCalls -Server MyUMServer

    Note

    When a Unified Messaging server is process cycling, the Get-UMActiveCalls cmdlet will not return a list of all calls for the retired process and the active process. It returns the active calls only for the new process.

For more information about syntax and parameters, see Get-UMActiveCalls.
