Create a Hybrid PSTN Usage

  • Article

 

This step creates a usage specifically for your Lync Online users, which is called HybridVoiceUsage. The new PSTN usage must be tag or global scope. You can also use an existing PSTN usage as long as it is tag scope or global scope.

Using Windows PowerShell command-line interface to create a PSTN usage

  1. Log on to the computer as a member of the RTCUniversalServerAdmins group, or as a member of the CsVoiceAdministrator, CsServerAdministrator, or CsAdministrator role. For details, see Delegate Setup Permissions.

  2. In the Lync Server Management Shell, type the following commands, replacing the placeholders with the correct information for your organization:

    Set-CSPstnUsage -Usage <String>

    For example:

    Set-CSPstnUsage -Usage @{add="HybridVoiceUsage"}
