While this is hilariously funny, especially the part about the guy talking to the wall at 1:50, this is why I rarely have telephone conference calls.
Remember people, IP Telephony/VoIP is all fail. We all hate web conferences because they all work badly (some much worse than others, thats right Webex I’m looking at you) . It works for a few people in a few unique circumstances. You need to be thinking of new tools and methods to replace telephone calls – it’s 2014 after all, this is the future.
