SMS Lib调用通知无效

Question

我正在使用SMSLib 3.5.2库来发送/接收短信。当我尝试通过实现回调方法时，我没有收到消息。此外，甚至从不调用来电通知的功能。 任何帮助都将受到高度赞赏.....

gateway = new SerialModemGateway(MODEM_IDENTIFIER, SERIAL_PORT, BAUD_RATE, MODEM_MANUFACTURER,"");

gateway.setInbound(true);

gateway.setOutbound(true);

ICallNotificationI ic = new ICallNotificationI();
Service.getInstance().setCallNotification(ic);

Service.getInstance().addGateway(gateway);

Service.getInstance().startService();

，实现接口ICallNotification的类永远不会被调用：

public class ICallNotificationI implements ICallNotification {

@Override 
public void process(AGateway gateway, String callerId) {

    System.out.print("Hello Buddy in the call");
    MLog.log(Level.INFO, ".ICallNotification.Process", "We rececived call"
            + " from this number "+callerId);

}
