bvtech,
The MiVO-400 is an Aastra product and the Mitel 3000 was an Inter-Tel product that have nothing in common. The 3000 doesn't have any hospitality features associated with it. The Mitel 3300 on the other hand does have hospitality built into it because that is a homegrown Mitel product.
Also, the MiVO-250 didn't replace the new MiVoice 5000. The MiVO-25 used to be an Inter-Tel product called the CP-5000 or the HX-5000 depending on the hardware platform it was on. When Mitel bought out Aastra they also had a 5000 model so Mitel renamed the HX-5000 to the MiVO-250 and the Aastra product is now the MiVoice 5000 product.
Hopefully that clears up the confusion. I have to go take an Excedrin Migraine now.
Thank,
Steven
