You can test the operation of Unified Messaging (UM) and related connected telephony equipment. When you perform the following procedure, the Client Access and Mailbox server tests the full end-to-end operation of the voice mail system. This includes the telephony components connected to the Client Access and Mailbox servers, including VoIP gateways, Private Branch eXchanges (PBXs), IP PBXs, and cabling.

For additional management tasks related to troubleshooting UM, see UM services procedures.

Use the Shell to test the operation of the Unified Messaging and telephony components

This example tests the ability of the UM IP gateway to listen on TCP port 5060 for incoming SIP requests.

Test-UMConnectivity -ListenPort 5060 -UMIPGateway MyIPGateway

This example tests the ability of the local Mailbox server to use an unsecured TCP connection instead of a secured mutual TLS connection to place a call through a UM IP gateway named MyUMIPGateway by using the telephone number 56780.

Test-UMConnectivity -UMIPGateway MyUMIPGateway -Phone 56780 -Secured $false

This example tests the Outlook Voice Access number on a dial plan by using a SIP URI. This example can be used in an environment that includes Lync Server.

Test-UMConnectivity -UMIPGateway OCSGateway1 -Phone "sip:SIPdialplan.contoso.com@contoso.com"

Note

You can set the -Timeout parameter with a value of less than 5 seconds. However, we recommend that you always configure this parameter with a value of 5 seconds or more. Use mode 2 when the ­UMIPGateway parameter is specified in the command-line syntax.
