I have gone to a couple of the conferences. I will have to agree with the person stating the sessions presented by the end users are more helpful, more "how to" info. I have attended several sessions put on by vendors, business partners and Avaya that feel like a sales pitch. For example, I would guess a lot of Avaya presentations will cover what has just been released or subject to release this summer. The sessions by the end users tend to be more along the lines of a mini-class, and always seem to get good participant discussions going about the subject matter. And the end user's equipment and versions aren't always the latest and greatest, and they are willing to discuss programming from CMS r12 or CM 2.2,..., where the vendors/business partners and Avaya will probably discussing CM 4.x.
