This is an event that fires when the user presses the start call button.
document.addEventListener("startcallbutton", yourCallbackFunction, false);
If you need to override the default start call behaviour you can register an event listener for the ‘startcallbutton’ event.
Typically, you will want to attach an event listener with document.addEventListener
once you receive the Cordova ‘deviceready’ event.
document.addEventListener("startcallbutton", onStartCallKeyDown, false); function onStartCallKeyDown() { // Handle the start call button }
