I went to a couple of schools in Richardson, TX from a company called Global Knowledge that was affiliated with Nortel some how. I just went to the 101 class and the moves, adds and changes class. They were very over priced for what you get out of it. One idea you may think about if your company is paying for it is to have a consultant or a tech from a phone vendor come out and do some training, for us the hourly rate was cheaper than school. But I work for the feds so I know the rates we pay per hour a probably cheaper than most. And you get alot more of what you actually can use then a bunch of the junk they teach in school.
