Phone calling is a traditional telephone call, when the caller and the callee or both are using a phone line using a mobile device or a land line phone.


In-app voice calling is a pure software-based call, where audio and/or video information is transmitted over the Internet between caller and callee. Once integrated in your app, users can make calls from their computers or mobile devices.
