For a lack of a better place to put this....

I am looking for some advice from all the ppl out here in AO land, I have been recently instructed by my boss that if I can learn about our PBX/Avaya switch network that I can get hired on full time by the company I am being contracted to, taking over their telephony.

This would include patching down all network and telephone drops while still providing network support and Telephone support

Current Setup:
We have 2 avaya switches
Main Phone Switch is a Definity switch (big SOB)
Voicemail is a Intuity switch

My boss told me if i can start by learning just basic commands and how to's (ie setup new extensions, move phones, create voicemail accts) that he could get me hired on and then the company would pay for future trainings. Well thats just the thing, i dont even know where to start looking,

I checked out Avaya's website and their learning center didnt really do much other than confuse me. I am hoping someone out here has some experience or may be able to point me to some reading materials or perhaps some tutorials or online courses. I am looking for online classes that would be under $200 US.

Thanks in advance
