After three tries I finally passed my certification for the NEC SV9500 phone system. This is the largest phone platform that NEC supplies, which means it is also the most complicated. I have been working with phone systems for almost twenty years and I have never taken a more difficult test. Most systems come with two manuals, hardware and software, this one had eleven. I still require eight more certs on the system to get me fully certified on all the peripherals.
