Inter-Tel Axxess End of Life & Replacement

System type

Digital PBX (Axxess / Mitel 5000 / MiVoice Office 250)

Status

Discontinued — absorbed by Mitel

Manufacturer support

End of life

In service

1990s–2010s

Inter-Tel was acquired by Mitel in 2007. The Axxess platform lived on as the Mitel 5000 and later the MiVoice Office 250 — which Mitel has since flagged for end of life. Whether your label says Inter-Tel, Mitel 5000, or MiVoice Office 250, it's the same aging system.

fvoip replaces it with a cloud platform that keeps your numbers and extension plan intact and gives every user a mobile and desktop app your Axxess never could.

Why it's time to move.

End-of-life lineageThe Axxess / Mitel 5000 / MiVoice Office 250 line has reached end of life on Mitel's roadmap.
Proprietary handsetsInter-Tel and Mitel 5000 digital phones are locked to the platform and can't move to a modern SIP system.
Processor and card scarcitySpare base servers and expansion cards are increasingly hard to source and unwarranted.
No native mobilityRemote work and mobile extensions were bolt-ons; fvoip includes them for everyone.

Your migration, step by step.

We rebuild your call flows on fvoip — auto-attendant menus, ring groups, business hours, and voicemail boxes — while Inter-Tel Axxess 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 Inter-Tel Axxess / Mitel 5000 still supported?

The Axxess line became the Mitel 5000 and MiVoice Office 250, which Mitel has flagged for end of life. Confirm your exact date with Mitel, but the platform has no forward roadmap.

Can I keep my Inter-Tel phones?

No — they're proprietary. Use them until cutover, then move to SIP handsets you can reuse or rent from $8.99/mo.

Will my extensions change?

No. We rebuild your extension map and auto-attendant on fvoip so the dialing experience stays the same.
