"Find and view several YouTube videos on unified communications. Identify the URLs for three that you think do a particularly good job illustrating the characteristics and capabilities of UC systems. Select the one that you think is best and briefly justify your selection." write a short two page paper about this topic, citing at least one major IT magazine or academic review. Focus on addressing the assignment statement at the end of the question. I am not interested in merely a 'book report', but your short analysis of the issue/problem the book wishes you to address. Thanks.
