After some unpleasent dealings with our service provider, the big boss would like to cut out third parties entirely in regards to Phone switch maintenance.
I have googled a bit but seem to come up short searching for online training/certs for NEC products. Is this something only NEC offers?
Also what are some pre-reqs to taking an NEC specific course.
I am a fluent network admin, and can muddle through the hardware aspects of telcom, but have no formal training except "oh-sh*t it's down, fix it" when it comes to phone/PBX programming.
What certifications, classes etc have any of you taken? Are they even worth it? should I just rtfm :read: ?

thanks
