-## Overview of telephony
-Whenever your users interact with a traditional telephone number, calls are facilitated by PSTN (Public Switched Telephone Network) voice calling. To make and receive PSTN calls, you need to add telephony capabilities to your Azure Communication Services resource. In this case, signaling and media use a combination of IP-based and PSTN-based technologies to connect your users. Communication Services provides two discrete ways to reach the PSTN network: Voice Calling (PSTN) and Azure direct routing.

To make and receive PSTN calls, you need to add telephony capabilities to your Azure Communication Services resource.

 ### Voice Calling (PSTN)
 
 An easy way of adding PSTN connectivity to your app or service, in such case, Microsoft is your telco provider. You can buy numbers directly from Microsoft. Azure Cloud Calling is an all-in-the-cloud telephony solution for Communication Services. It is the simplest option that connects Communication Services to the Public Switched Telephone Network (PSTN) to enable calls to landlines and mobile phones worldwide. Microsoft acts as your PSTN carrier, as shown in the following diagram:
