 /**
- * Provides access to Telecom-related functionality.
+ * Provides access to information about active calls and registration/call-management functionality.
+ * Apps can use methods in this class to determine the current call state. Apps can also register new
+ * {@link PhoneAccount}s and get a listing of existing {@link PhoneAccount}s.
+ * <p>
+ * Apps do not instantiate this class directly; instead, they retrieve a reference to an instance
+ * through {@link Context#getSystemService Context.getSystemService(Context.TELECOM_SERVICE)}.
+ * <p>
+ * Note that access to some telecom information is permission-protected. Your app cannot access the
+ * protected information or gain access to protected functionality unless it has the appropriate
+ * permissions declared in its manifest file. Where permissions apply, they are noted in the method
+ * descriptions.
