Avaya filed for bankruptcy in 2023 and has shifted its focus away from small businesses

Avaya IP Office is still commercially available and supported on current releases (R12.0). However, Avaya filed Chapter 11 bankruptcy in February 2023, emerged in May 2023, and has since announced a strategic pivot toward large enterprises (200+ seats). As of June 30, 2025, Avaya discontinued support for contact centers with fewer than 200 seats. For small and medium-sized businesses currently running Avaya IP Office, the question isn’t whether to plan a migration — it’s when and to what.

Avaya IP Office — Evaluating Your Options

Moving Away from Avaya IP Office? Here’s What Phonewire Recommends for Small Business.

Avaya IP Office served hundreds of thousands of small businesses for decades — reliable call handling, voicemail, auto-attendant, and a wide range of expansion options. But the landscape has changed. Between two bankruptcy filings in six years and an explicit strategic shift away from the SMB market, many small business owners are now asking the same question: is it time to find a vendor that’s actually committed to businesses our size?

Phonewire has been installing and supporting business phone systems since 1998. We’ve helped many businesses migrate off Avaya IP Office — keeping their numbers, preserving the features they valued, and delivering a managed system with a single point of accountability for support and maintenance.

Still Running Avaya IP Office?

If your system is currently working on a supported release (R12.0 or R11.1.3+), there’s no emergency today. But it’s worth assessing your release version, hardware age, and support contract status — and planning your migration before a failure or support gap forces a rushed decision.

Avaya System Failing or Unsupported?

If you’re running Avaya IP Office R11.1 or earlier, or if your IP500v2 hardware is failing and replacement parts are difficult to source, Phonewire can deploy a modern replacement with a fast turnaround — nationwide installation, same-day configuration, and U.S.-based support from day one.

Why Small Businesses Are Moving Off Avaya IP Office

Two bankruptcies in six years — and an explicit pivot away from SMB. Avaya filed for Chapter 11 bankruptcy in January 2017 and again in February 2023. After emerging from its second filing, Avaya’s stated strategy has been to focus on large enterprise customers (G1500 — 1,500+ seats) and its cloud-based Avaya Experience Platform. The June 2025 announcement discontinuing support for contact centers with fewer than 200 seats made the direction explicit. Small businesses are not Avaya’s priority market anymore.

Shrinking reseller and support ecosystem. As Avaya has pivoted upmarket, many of its SMB-focused resellers and certified partners have moved to competing platforms. Finding a qualified Avaya IP Office technician who knows the system deeply — and can respond quickly when something breaks — is harder than it was five years ago. The Avaya partner ecosystem for small business support has contracted significantly.

Aging hardware with no clear successor. The IP500v2 — the most common Avaya IP Office hardware in small businesses — is aging hardware with no direct next-generation successor in the SMB segment. Avaya’s current investment is going into cloud infrastructure, not new on-premises SMB hardware. Replacement parts for older IP500v2 units are increasingly difficult to source.

Per-user licensing that compounds as you grow. Avaya IP Office’s licensing model — where each user, trunk, feature set, and application requires separate licensing — creates ongoing cost complexity as businesses add staff or change how they communicate. Phonewire’s hybrid on-premises system uses a flat annual license of $699/year for up to 20 users, regardless of features used.

No single point of accountability. In the Avaya channel model, the hardware, software licensing, SIP trunks, and support often come from different vendors — the reseller, Avaya directly, the carrier, and a maintenance contractor. When something breaks, the finger-pointing starts. Phonewire owns the entire system — hardware, configuration, numbers, and support — under one relationship. When something needs attention, there’s one phone call.

What Avaya IP Office Users Valued — And What Replaces It

✓

Robust call routing and hunt groups. Avaya IP Office has excellent call routing capabilities — time-based routing, ring groups, call queues, overflow rules. Phonewire’s hybrid system replicates all of this, configured by Phonewire’s team before installation day. You describe how you want calls to work; we build it.

✓

Voicemail Pro and voicemail to email. Avaya’s Voicemail Pro is one of the strongest voicemail systems on the market. Phonewire includes voicemail to email on every installation — audio delivered to your inbox, with optional human-powered transcription so you can read messages like email.

✓

On-premises ownership and control. Many Avaya IP Office customers chose it specifically because they wanted hardware on their premises — their system, their data, their control. Phonewire’s hybrid delivers the same ownership model on modern open-standard SIP technology, with a flat annual license and professional support that Avaya’s channel increasingly can’t match.

✓

Business continuity during internet outages. Avaya IP Office’s resilience features were a genuine differentiator. Phonewire’s hybrid can include built-in cellular failover — if your internet goes down, calls automatically continue on a 4G LTE backup in under one second. No manual intervention, no dropped calls.

What a Migration from Avaya IP Office to Phonewire Looks Like

Free consultation and system assessment. Phonewire reviews your current Avaya IP Office setup — release version, hardware model, number of users, call routing rules, and what’s working vs. what needs to change. We give you a specific recommendation and all-in pricing. No generic quote ranges — a real number. Schedule yours here.

Network assessment by a CCNA-certified engineer. Before installation day, a Phonewire engineer reviews your internal network — QoS settings, internet reliability, router configuration — to confirm the infrastructure is ready for the new system. No surprises on installation day.

Number porting — your numbers stay yours. All existing business phone numbers are ported to the Phonewire system. Porting typically takes 2–4 weeks. During the transition, your Avaya system remains live and call forwarding routes calls seamlessly. There’s no gap in service.

Professional on-site installation — all hardware, all configuration. Phonewire field installs everything at your location. New desk phones, new system hardware, and all cabling. Our PM handles all portal setup and programming — you don’t touch a configuration screen until your system is already working. See how installation works.

Staff training and go-live on day one. Phonewire conducts end-user training for your entire staff — voicemail setup, phone operation, and mobile app — the day of installation. Administrators receive separate portal training. By end of day, your team is operating on the new system and the Avaya equipment is ready for decommission.

Frequently Asked Questions

Is Avaya IP Office actually discontinued?

Not entirely. Avaya IP Office R12.0 is the current release and remains supported as of early 2026. However, older releases (R11.1 and earlier) are losing software patch and security support. More significantly, Avaya announced in 2025 that it is discontinuing support for contact centers with fewer than 200 seats and is explicitly focusing its investment on large enterprise customers and its cloud platform. For small businesses, the practical trajectory is clear even if the formal EOL date hasn’t been announced.

What release of Avaya IP Office am I running, and does it matter?

Yes — significantly. If you’re running R12.0, you’re on the current supported release and have more time. If you’re running R11.1, R11.0, R10.x, or earlier, you’re already in a reduced-support window with limited or no software patch availability. Your Avaya system’s admin portal shows the current release version, or your reseller can confirm it. Phonewire can also help you identify this during a free consultation.

Can I keep my existing phone numbers when I migrate?

Yes. Your business phone numbers port to the Phonewire system regardless of where they’re currently hosted. Porting typically takes 2–4 weeks depending on your current carrier. During the transition, call forwarding from your Avaya system keeps calls connected. Your numbers are yours — no Avaya involvement is required to port them.

Can I reuse my existing Avaya IP phones?

Possibly. Avaya’s proprietary H.323 phones (1600, 9600 series) are generally not compatible with non-Avaya systems. SIP-compatible Avaya phones may be adoptable depending on the model. Phonewire evaluates existing handsets during the consultation — if reuse is possible and cost-effective, we’ll tell you. If replacement is required, Phonewire recommends Snom, Yealink, Poly, or Panasonic phones matched to your deployment environment.

How does the 5-year cost compare to staying on Avaya?

The Phonewire 5-year TCO analysis shows that the on-premises hybrid system typically runs $19,000–$22,000 over five years for a 20-user business — compared to $65,000–$83,000 for a comparable legacy PBX deployment when you factor in licensing, maintenance contracts, and support costs. Avaya IP Office’s per-user, per-feature licensing model makes the gap even wider as user count grows.

What happens to my existing Avaya IP Office system after migration?

Once number porting is complete and your new Phonewire system is live, your Avaya IP Office hardware can be decommissioned. Phonewire can advise on proper decommission procedures. The Avaya hardware itself has some resale value in the secondary market if it’s a recent-generation unit in good condition.
