What Happened to the Mitel 3300 Controller? Has Mitel Stopped Selling the 3300 Controller?

The Mitel 3300 Controller was renamed MiVoice Business and is no longer sold under the 3300 name.

What should I do next? What are the best alternatives and replacements to the Mitel 3300 Controller?


The best alternative/replacement to many customers who used or considered the 3300 Controller is MiVoice Business, a modern unified communications system.

For small businesses or branch locations up to 150 users, you should consider the SMB Controller (SMBC), upon which you can build MiVoice Business or MiVoice Office 400, depending on your geography.
