If a user cannot receive inbound calls from the PSTN gateway, you can troubleshoot the issue as follows:

  1. Verify that the Mediation Servers and Enterprise Voice gateways are connected and available by using the VoIP Test Set.

  2. Verify that the Mediation Server is assigned a default location profile and is configured to use the Standard Edition Server or Enterprise pool on which the user is homed. For details about configuring a Mediation Server with a default location profile and specifying the Standard Edition server or Enterprise pool, see the Deploying Enterprise Voicedocumentation.

  3. Verify that the call is traversing Office Communications Server and that it is being presented to the Mediation Server and to the PSTN gateway. For details, see Network Issues from the PSTN to the Mediation Server.

  4. Verify that the phone number dialed is associated with a user who is enabled in Active Directory for unified communications (UC), as described in Active Directory Domain Services Attributes and Descriptionsin the Preparing Active Directory Domain Services for Office Communications Server 2007 R2 deployment documentation .

  5. Review the regular expressions for number normalization and translation, as described in Translation Pattern and Regex Validation. You can also turn on the TranslationApplication traces through the Office Communications Server 2007 R2 Logging Toolto help determine whether the number is correctly normalized.

  6. Review the InboundRouting traces in the Logging Tool to see if the call is being routed to the appropriate user.

  7. Check Event Viewerfor failures of the inbound routing application.
