Avaya built much of the on-prem phone world: Partner ACS, Merlin, Definity, and later IP Office sat in millions of offices. But the company filed for Chapter 11 bankruptcy protection in 2017 and again in 2023, and its stated direction since has been large enterprise and cloud, with far less attention on the small-business systems that made its name. Older lines like Partner ACS reached end of life years ago, and the dealer network that once supported small Avaya systems has thinned considerably. If your Avaya system still runs, it runs on borrowed time and secondary-market parts.

Migrating is more routine than it feels. Your phone numbers belong to you under FCC porting rules, and we port them to fvoip for free: local numbers in 3 to 10 business days, toll-free in 10 to 15. Our team maps your existing setup, including your auto-attendant tree, hunt groups, and extension list, then rebuilds it on fvoip before anything changes. We run the new service in parallel with the Avaya system during the port, so your callers never hit a dead line. When cutover day arrives, it is a non-event: calls simply start ringing the new phones.

The economics usually settle it. An aging Avaya PBX carries maintenance contracts, per-visit technician fees, PRI or analog trunk charges from a legacy carrier, and the standing risk that one failed card takes the office dark while a used part ships from a reseller. fvoip replaces all of that with a published per-user price starting at $21 per month, no contract, no setup fees, and hardware you can buy outright or rent from $8.99 per month. Businesses leaving legacy carriers and PBX maintenance behind typically cut phone spend 40 to 60 percent.

Frequently asked questions

Our Avaya IP Office still works. Why move now?
Because the risks compound quietly: parts get scarcer, the techs who know the system retire, and Avaya's post-bankruptcy focus is large enterprise. Migrating on your schedule beats migrating during an outage.
Can we keep our phone numbers?
Yes, all of them, including toll-free. Porting is free and we coordinate it so the Avaya system stays live until the new service carries your calls.
Can you replicate our auto-attendant and hunt groups?
Yes. We document your current call flows and rebuild them on fvoip before cutover, then refine anything you want changed. Multi-level auto-attendant and business-hours routing are included on every plan.
What happens to our Avaya handsets?
Avaya's proprietary digital sets do not carry over, but that is usually good news: modern Yealink, Poly, and Grandstream phones arrive auto-provisioned, and you can rent them from $8.99 per month instead of buying outright.
