In total, there are four exchanges (two questions and two answers). However, if you look closely, the second person's reply of 'Yes' already confirms that they can both hear and speak. Therefore, the second 'Can you hear me?' is unnecessary. With just three exchanges (one question and two answers), both people know that they can send and receive messages.
