Personally, I wouldn't dwell on it too much. I'd simply acknowledge the fact that you heard your name being called. Simply say a thank you and move on. Continue asking for communication. Like Verunia said: don't jump to conclusions. I know it's tempting since we want to hear from our guides (I'm still waiting to communicate with mine, too), but in my opinion, there are greater signs to be had from them, and you'll receive them in due time.
So just let them know of your intent to communicate - perhaps ask them to show you the best way to do so.
