Ended

In service

1980s–2010s

Iwatsu (Omega/ADIX/ECS), Comdial (DX-80, FX), and Vodavi (STARPLUS, XTS) were common small-business key systems that are now discontinued and effectively orphaned — Comdial's assets scattered years ago, and Iwatsu and Vodavi are long out of the US market.

If your office still runs one of these, you're maintaining hardware no one makes anymore. fvoip retires the box, keeps your numbers, and rebuilds your call flow in a supported cloud.

Why it's time to move.

No manufacturer behind themIwatsu, Comdial, and Vodavi are discontinued and orphaned — there is no OEM support, warranty, or parts pipeline.
Used-market hardware onlyKSUs, cards, and proprietary phones come from third parties with no guarantees.
Copper-line dependenceMany of these systems rely on analog lines carriers are phasing out.
No modern featuresNo mobile app, no remote extensions, no encryption — capabilities fvoip includes as standard.

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 Iwatsu, Comdial & Vodavi 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.

What you keep

Your phone numbersWe port every direct-dial and main line to fvoip — callers keep reaching you at the same numbers, with no gap in service.
Your extensions & menusWe rebuild the extension map, auto-attendant, ring groups, and business hours your team already knows.
Business continuityfvoip runs in parallel with the old system and cuts over only when you approve — phones never stop ringing.
Compatible SIP phonesReuse standards-based SIP desk phones where possible, or rent auto-provisioned handsets from $8.99/mo.

Frequently asked questions

Are Iwatsu, Comdial, or Vodavi still supported?

No. All three are discontinued and orphaned — Comdial's assets were dispersed years ago, and Iwatsu and Vodavi have long left the US market. Support and parts are third-party only.

Can I keep my existing phones?

These systems use proprietary handsets that won't work on fvoip. Use them until cutover, then move to SIP phones you can rent from $8.99/mo.

Will I keep my phone numbers?

Yes. We port your numbers to fvoip and rebuild your extensions and auto-attendant before cutover, so nothing changes for callers.

Ready for a phone system that just works?

Set up in a day. Keep your numbers. Cancel anytime — every plan is month-to-month with a 30-day money-back guarantee.
