View the Number of Active Calls for a UM Server

  • Article

Applies to: Exchange Server 2010

You can view the number of active Unified Messaging (UM) calls 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 Active Directory to determine which Unified Messaging servers must be contacted.

Use the Shell to view the number of active calls for a Unified Messaging server

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM server" entry in the Unified Messaging Permissions topic.

This example displays the details of all active calls on the local Unified Messaging server.

Get-UMActiveCalls

This example displays the details of all active calls on a Unified Messaging server named MyUMServer.

Get-UMActiveCalls -Server MyUMServer

This example displays the details of all active calls being processed by a UM IP gateway named MyUMIPGateway.

Get-UMActiveCalls -IPGateway MyUMIPGateway

This example displays a list of active calls associated with the UM dial plan named MyUMDialPlan.

Get-UMActiveCalls -DialPlan MyUMDialPlan

Note

When a Unified Messaging server is process cycling, the Get-UMActiveCalls cmdlet won't 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.
