I'm gonna have to agree wth you DRPBX, manuals only go so far. If the company is willing to pay for certification then I'm gonna take the course. It looks a little better on your resume anyway. I'm going to hire someone who know's the in and outs of the system rather than someone that opens a book and reads how to do things. I'm sure there are many tech's that rely on documentation to get things done. There are some key systems you can do that with such as the Northern's. All your programming is done from the phones. All in all I'll take the certification if they are willing to pay for it!!!
