So I signed up for Avaya University so I could finally get some training on this system I've Admin'd for 2 years without any prior Telecom experience 
I'm completely overwhelmed by my options to say the least.
I admin everything about the current system, s8500 and Intuity Audix but have been letting our contract vendor handle the big stuff (gateway installs, firmware upgrades, etc). So I'm not sure where to focus my attention Training or Certification wise. Is it worth it to try and learn how to deploy gateways? Or should I let the vendor continue to install them so it's their fault when it doesn't work?
I'm most definitely called upon to do more than just MACs in my curent position but as the sole Telecom person I do process my share of them. What focus (Cert) should I concentrate on? What (if any) Avaya training do you suggest?
I've had zero formal training and have survived on documentation, Avaya's website and this forum up until now. My prior background was Network related so VOIP was easy to pickup as was taking care of the digital and analog punch blocks (we're a mix of Prologix and VOIP Gateways). I feel there are a great deal of "holes" in my knowledge scope as I tend to learn enough about the issue at hand to solve the problem and then move on to the next. Is it worth starting from scratch with the training?
I appreicate any feedback you guys can toss at me!
