Mitel's SX-200 has roots in the 1980s, and the older MiVoice 3300 ICP controllers that followed have reached end of life. If your Mitel is one of these generations, it's on Mitel's retirement list, not its roadmap.

fvoip replaces the controller and its cabinet with a cloud platform, ports your numbers, and rebuilds your call routing — with native mobile and desktop apps included for every user.

Why it's time to move.

End-of-life and support details reflect published information at the time of writing and can change — always confirm current status with the vendor.

Your migration, step by step.

We rebuild your call flows on fvoip — auto-attendant menus, ring groups, business hours, and voicemail boxes — while Mitel SX-200 & 3300 ICP keeps answering. You test everything on temporary numbers, and we port the real numbers only once you sign off. If anything looks wrong, the old system is still there.

Frequently asked questions

Is the Mitel SX-200 or 3300 ICP still supported?
The SX-200 and older 3300 ICP controllers have reached end of life. Confirm your specific controller and software load with Mitel, but these generations have no forward roadmap.
Can I reuse my Mitel phones?
Legacy Mitel digital handsets are proprietary. Some newer SIP-capable Mitel models may re-provision; otherwise switch to SIP phones you can rent from $8.99/mo.
How disruptive is the cutover?
Minimal. fvoip runs in parallel with your Mitel and we port numbers only after you've approved the new call flows.
