Support anonymous PSTN callers to start a static meeting without an authenticated user in Skype for Business Server 2015

In Microsoft Skype for Business Server 2015, anonymous PSTN callers now are supported to start a Static/My dedicated meeting space meeting in addition to Dynamic meetings. This is true regardless of whether an authenticated user is joined.

To support this new capability, a dial-in conferencing setting named "AllowAnonymousPstnActivationForDedicatedMeetings" is now added. By using this setting, the AllowAnonymousPstnActivation parameter (an existing setting) enables dynamic meetings to be started only by anonymous PSTN callers, and the AllowAnonymousPstnActivationForDedicatedMeetings parameter (the new setting) additionally enables this change for static meetings. The default value of the AllowAnonymousPstnActivationForDedicatedMeetings parameter is false.

• To enable anonymous PSTN callers to start Static and Dynamic meetings, use the following cmdlet:

Set-CsDialInConferencingConfiguration -Identity < global or site:sitename> -AllowAnonymousPstnActivation $True -AllowAnonymousPstnActivationForDedicatedMeetings $true

Note The AllowAnonymousPstnActivation parameter must be set to true to be able to set -AllowAnonymousPstnActivationForDedicatedMeetings to true.

• To enable anonymous PSTN callers to start only Dynamic meetings, use the following cmdlet:

Set-CsDialInConferencingConfiguration -Identity < global or site:sitename> -AllowAnonymousPstnActivation $True -AllowAnonymousPstnActivationForDedicatedMeetings $false
