You can buy Calling Plan if it is offered for your purchasing program and in your country or region. In addition, using on-premises voice connectivity, you can connect Phone System to your existing telephony infrastructure—such as on-premises SIP trunks offered through your local/regional telco—enabling Phone System to perform call control and call management features.
If you are an Office 365 E5 or Phone System customer, you can connect your existing PSTN service provider with Microsoft cloud-based call control. Scenarios are based on whether a customer already has a Skype for Business Server deployed. You can set up a new server pool or use an existing Skype for Business Server deployment to configure it to connect to Phone System functionality that is covered under existing server licensing.

If you don’t have an existing server, you can use a minimal Skype for Business Server deployment through the Cloud Connected Edition that includes four preconfigured Virtual Machines (VMs) deployed on customer-owned Windows Servers. Skype for Business Server roles in VMs are not paid roles and are licensed for use with Phone System.
Office 365 Calling Plan is subject to geographical and channel availability. See countries and regions that are supported for more information.
