+### - checkReachability
+
+On Android when the application is in background, after a certain delay the OS will close every connection with informing about it.
+So we have to check if the application is reachable before making a call from the native phone application.
+
+```js
+RNCallKeep.addEventListener('checkReachability', () => {
+  RNCallKeep.setReachable();
+});
+```
