To enable Microsoft® Lync® or Skype® for Business users in an enterprise to join Vidyo conferences, VidyoCloud customers must federate their on-premise Skype for Business Server 2015 (or Office 365®) with the VidyoCloud Skype for Business server.
For VidyoCloud customers with an on-premise Skype for Business Server installation, we recommend you use either the “Discovered Partner Domain (aka Open Enhanced Federation)” or “Allowed Partner Domain (aka Enhanced Federation)” federation type. The domain to federate with is vidyocloud.com.
For VidyoCloud customers with an Office 365 account, you must enable external access for your users to communicate with the vidyocloud.com domain.
For more details on how to set up federation and external access for your Skype for Business or Lync users, please consult your Skype for Business Server administrator.
