It is because of our requirement for redundancy. Mitel is stating that you have to literally buy TWO 5000s to be redundant, whereas the 3300 has this as a part of its structure. In a new building we are moving to, we will have to move to IP also, due to the wiring structure, so we will have to replace the digital phones, which of course adds a large chunk to make it equivalent in that regard to the 3300
