As has already been said above,....... it's all about who you buy from rather than brand.
Although,.... I am partial to the Avaya IPO as that is what we sell and service and find it to be a real work horse.
Avaya won't be the cheapest, but do your research (as you seem to be) and make sure you are comparing apples to apples before making your decision.
Oh,..... and welcome to the board.
