Getting up to speed quickly - ITEXPO or Astricon?

I’m trying to learn more about the entire voip/Asterisk “ecosphere”; eg. business, markets, technologies, products, etc., and plan to attend either Astericon ( Budget will probably not permit me to attend both. Any recommendations on which to attend, and why, would be appreciated.



[Aside to moderator - I should have posted this to [events], but can’t figure out how to move it. Can you help?]
