Use this Cordova plugin to make your VOIP (audio and video calling) apps feel more native by having calls within your app appear like regular phone calls. You can display the incoming call screen and outgoing call screen by simply calling a JavaScript function. Ringtone sound, call icon, and several other features can be customized. This plugin takes advantage of iOS CallKit and Android ConnectionService in order to allow you to give your app users a better experience by having audio and video calls from your app appear like regular phone calls. WebRTC goes very well with this plugin.
