One of the joys of working for a US firm is that at 3pm every day now we all have 2 hours of conference calls to attend.  Happily in Microsoft, most are live meetings now and most are recorded. The challenge is, you see, that now I almost always have a clash with another live meeting.  So the best solution I've found is don't attend any of them, just listen to the recordings on triple speed.  Yes, you do feel a bit like Neo in the Matrix, learning kung fu but you can listen to two meeetings in less time thatn it would take you to attend just one of them.  It really is absolutely understandable as well which i do find surprising even now.
