VoIP and Internet Telephony are fast moving areas. Telephony in general has a long history and has had dramatic effect on culture and society around the world. Unfortunately, 14 weeks is not enough time to cover all of the emerging technical aspects nor the rich cultural and societal impact that telephony has had. In order to add more variety into the course material each student will be assigned to a group to give a short (15 minutes maximum) presentation on one historical, cultural, societal or emerging technical aspect that we are not covering in course material.
