Mike said most of it right there. I too came from a heavy Nortel background, but I also had a heavy background in Partner/Magic/Definity so I think I was ahead of most of the Nortel only guys. It is, and continues to be a steep learning curve, but also in my opinion the best long term option. I like IPO's Manager software much, much more than I ever liked Element Manager or NRU. With R7 and above you can re-use nortel sets so they wont have as big of a hit on system purchase. Contact Matt, Mongo5150, on this board. He was extremely helpful to us in getting on board as an Avaya BP. He can get you in contact with the right people. There are also many sources for support outside of Avaya as well such as boards like this and sites ran by some of the IPO Office experts..
