Avaya IP Office customers weighing a move to Avaya Cloud Office have been handed a simpler version of a more complicated story. The shorthand version is straightforward: IP Office is mature, ACO is the cloud answer, time to sign the renewal. The longer version — the one that actually affects multi-year platform decisions — is worth understanding before anyone commits.

Both platforms work. Thousands of businesses run IP Office every day without incident, and Avaya Cloud Office has a growing installed base of its own. This post isn’t an argument against either one. It’s an argument for understanding the full picture — how the products are structured, how the commercial relationship behind Avaya Cloud Office has evolved, and what other options exist — before treating the default migration path as the only migration path.

Businesses that skip this context sometimes discover it later, usually at the worst possible moment. A renewal cycle. A feature request that isn’t on the roadmap. A support escalation that routes somewhere unexpected. The cost of learning these things in advance is an hour of reading. The cost of learning them after signing tends to be measured in years.

What Avaya IP Office and Avaya Cloud Office Actually Are

Avaya IP Office is a mature on-premise PBX platform with a long track record in the SMB market, and Avaya Cloud Office is a cloud UCaaS product delivered in partnership with RingCentral — two different products with two different architectures and two different strategic trajectories.

IP Office has served the small and mid-sized business market dependably for more than two decades. It routes calls, manages extensions, runs auto-attendants, and handles call queues with the kind of steady competence that keeps IT managers from losing sleep. Avaya continues to support the platform for existing customers. What’s changed is where Avaya’s fresh development investment is directed — publicly, that focus has shifted toward the cloud portfolio, including Avaya Cloud Office, Avaya Experience Platform, and Avaya Infinity.

Avaya Cloud Office launched in 2020 as Avaya’s cloud UCaaS answer. The architecture is public and well-documented: ACO runs on RingCentral’s platform, with Avaya providing brand, channel, and — in hybrid deployments — integration with Avaya Aura telephony. The arrangement lets Avaya offer cloud capabilities without building a second UCaaS stack from scratch, and it gives RingCentral access to Avaya’s enterprise and SMB channel footprint. Neither of those facts is hidden. They’re just worth knowing.

One practical implication of that architecture: Avaya Cloud Office typically tracks RingCentral’s feature roadmap on a brief delay. That’s how white-label partnerships work across the industry — integration, QA, and localization take time. It isn’t unique to Avaya or RingCentral. For IP Office customers accustomed to Avaya-built software running on an Avaya-controlled roadmap, it’s simply a different model to evaluate against.

How the RingCentral Partnership Evolved Through Avaya’s 2023 Restructuring

The commercial structure behind Avaya Cloud Office has changed meaningfully since the partnership launched — a fact that tends to surprise ACO customers who haven’t reviewed their contract paperwork in a while.

The original 2019 partnership agreement was substantial. RingCentral committed roughly $500 million in combined equity investment, licensing fees, and pre-paid royalties, and Avaya agreed to exclusive distribution of RingCentral’s UCaaS platform through the Avaya channel. Under the original structure, Avaya and its resellers sold ACO subscriptions, but RingCentral owned the underlying customer relationship. Resellers acted as agents, earning commissions while the contract and customer data lived with RingCentral.

That structure created some well-documented friction in the channel. Partners who had built their businesses on owning customer relationships weren’t universally enthusiastic about selling a product where the end customer technically belonged to a third party. Channel uptake, by most industry accounts, was slower than the partnership’s original projections assumed.

According to Bloomberg Law reporting, by late 2022 the partnership had accumulated more than $300 million in disputed contract liabilities, and both companies had engaged outside legal counsel. When Avaya filed Chapter 11 in February 2023, the restructuring resolved that dispute through a renegotiated commercial agreement rather than through litigation. Two things changed: RingCentral’s $125 million preferred equity stake in Avaya was eliminated in the restructuring, and the ACO sales model shifted so that Avaya and its partners could sell ACO on their own paper and own the customer relationship directly.

For existing ACO customers, service continued uninterrupted. What changed was the contractual framework underneath. Customers on contracts from the original agency model were, in most cases, migrated or renegotiated over time. It’s worth checking. The commercial structure of a phone system relationship doesn’t usually matter day to day — until it does.

For a look at how a very similar partnership pattern played out with another legacy vendor, the Mitel and RingCentral partnership breakdown covers comparable commercial dynamics from a different angle.

What Current Avaya IP Office Support and Development Looks Like

Avaya IP Office is in a mature product phase — stable, supported, and still receiving maintenance updates, though no longer the primary destination for Avaya’s new development investment.

This is a normal phase in the life of any enterprise software product. Vendors build, mature, and eventually transition products to maintenance mode while strategic investment moves to the next generation. IP Office has been in market for more than two decades. Its transition to a mature-phase product isn’t surprising, and it isn’t the end of the road for existing deployments.

What it does mean, practically, is that businesses planning three-to-five-year platform investments should review Avaya’s published roadmap with their reseller and understand where IP Office sits in Avaya’s long-term plans. New feature velocity on IP Office has slowed as Avaya’s engineering focus has shifted to cloud platforms. Partners who work with IP Office daily have noted longer intervals between major releases and a narrower scope of new capabilities as the roadmap has matured.

Avaya has also made some targeted portfolio adjustments that affect specific IP Office use cases. In June 2025, Avaya discontinued SMB contact center support for deployments under 200 seats — a formal narrowing of which customer profiles Avaya continues to serve with its legacy contact center products. For small businesses running IP Office with attached contact center functionality, that announcement is worth factoring into renewal planning.

None of this makes IP Office an unsupported platform. It does mean the platform’s trajectory looks different than it did during its active development years, and customers planning multi-year investments benefit from factoring that trajectory into their decision.

• Current IP Office status: supported, maintained, in mature product phase
• New development focus: Avaya’s cloud portfolio (ACO, Experience Platform, Infinity)
• SMB contact center support: discontinued for deployments under 200 seats as of June 2025
• Release cadence: slower than historical IP Office norms, per channel reporting

When Avaya Cloud Office Is the Right Fit — And When Other Options Deserve a Look

Avaya Cloud Office is genuinely the right answer for some Avaya IP Office customers and genuinely the wrong answer for others — the distinction usually comes down to deployment requirements, existing Avaya investment, and what happens after the migration.

ACO makes a strong case in a few specific scenarios. Large enterprises with significant Avaya Aura infrastructure already in place often benefit from the hybrid Aura-plus-ACO deployment model, which layers modern cloud collaboration onto existing Avaya telephony. Organizations with deep existing Avaya channel relationships often prefer continuity over vendor switching costs. And businesses that are fully committed to a pure cloud SaaS model, are comfortable with a multi-tenant architecture, and don’t need on-premise flexibility will find ACO a capable platform.

For SMB IP Office customers moving to cloud for the first time, the calculation gets more nuanced. Buying a RingCentral-powered product through Avaya’s channel means working within a two-vendor structure, which some businesses find valuable for continuity and others find unnecessarily complex. There’s no universally right answer — it depends on the buyer’s priorities.

There are also legitimate scenarios where ACO simply doesn’t fit. Businesses with compliance requirements that favor private-instance or on-premise deployment don’t have an on-premise option with ACO. Businesses in locations where internet reliability is variable may prefer architectures that keep internal calls local during outages. Businesses that prefer capital investment over recurring subscription cost may find capex licensing models more attractive than SaaS-only pricing. Cloud isn’t the right answer for every business, and pure cloud isn’t the right cloud architecture for every cloud adopter.

For those scenarios, IP Office customers have more options than the default reseller conversation sometimes suggests. Evaluating two or three platforms against documented requirements before signing anything is usually a few hours of work that pays for itself.

An Additional Option Worth Evaluating: Techmode

Techmode’s communications platform gives Avaya IP Office customers an additional option to evaluate alongside Avaya Cloud Office — particularly for businesses that want genuine deployment flexibility or want to keep a single-vendor relationship through the migration and beyond.

The platform is built on 3CX and available three ways: on-premise for businesses that need or prefer local deployment, cloud-hosted on Techmode’s private, triple-redundant AWS infrastructure for businesses ready to move to cloud, or hybrid for businesses with mixed requirements. Licensing comes in either perpetual capex or subscription opex, depending on how the business prefers to structure the expense. Features include AI call summaries, native SMS and MMS from business numbers, Microsoft Teams integration without a separate SBC project, mobile apps that work without a VPN, and a web-based admin portal that any office manager can navigate without calling IT.

The private-instance architecture matters in a specific way that tends to get glossed over in UCaaS conversations. When a multi-tenant cloud platform has a bad day, every customer on that infrastructure has a bad day at the same time. Private-instance deployment means each customer runs on their own dedicated infrastructure — not sharing compute, storage, or network resources with anyone else. For businesses whose phone system reliability directly affects revenue, that architectural difference shows up in the uptime math. For a deeper look at why, the private instance vs. multi-tenant breakdown explains the tradeoffs in plain language.

Techmode’s Premier Launch handles the migration itself. A dedicated project manager owns the project from kickoff through go-live, coordinating number porting, mapping and testing call flows before cutover, training users, and making sure the new system works on day one without the usual migration chaos.

White-glove installation isn’t a marketing phrase at Techmode — it’s how every deployment runs, because the alternative is the kind of rushed cutover that everyone remembers for all the wrong reasons.

After deployment, Techmode’s U.S.-based concierge support team handles ongoing support. Real people who know the system, know the business, and don’t require a case number to start a conversation.

No offshore call centers, no ticket queues that disappear into the void, no scripts that send every caller through the same seven-question diagnostic tree regardless of whether the caller is reporting a mild echo or a full outage.

That’s how Techmode maintains an NPS of 85 and an A+ BBB rating — the boring, unglamorous work of actually answering the phone when customers call.

None of this is an argument that Techmode is the right answer for every IP Office customer. It’s an argument that the Techmode platform belongs on the evaluation shortlist alongside Avaya Cloud Office, and that the shortlist approach — comparing two or three options against documented requirements — produces better long-term outcomes than accepting the default migration path without comparison.

Frequently Asked Questions

Q: Is Avaya Cloud Office built on RingCentral’s platform?

Yes. Avaya Cloud Office runs on RingCentral’s infrastructure and platform, with Avaya providing the brand and channel relationships. This structure is publicly documented and has been the case since the partnership launched in 2019. RingCentral drives the product roadmap and feature releases, and Avaya Cloud Office typically follows RingCentral’s own product release cycle on a slight delay.

Q: How did Avaya’s 2023 restructuring affect Avaya Cloud Office customers?

Avaya’s 2023 Chapter 11 restructuring included a renegotiation of the Avaya Cloud Office commercial agreement with RingCentral. The updated structure allowed Avaya and its channel partners to sell ACO on their own paper, rather than acting as agents for RingCentral. Existing customer contracts and service continued, though the commercial framework underneath changed. Customers with active ACO subscriptions are generally encouraged to confirm current contract terms directly with their reseller.

Q: What is the current state of Avaya IP Office development?

Avaya IP Office remains a supported product for existing customers, but Avaya has publicly shifted its strategic development focus toward its cloud portfolio, including Avaya Cloud Office, Avaya Experience Platform, and Avaya Infinity. IP Office is in a mature, stable product phase with ongoing maintenance and security updates. Customers evaluating long-term platform investments are encouraged to review Avaya’s current published roadmap to understand how IP Office fits into their multi-year planning.

Q: Does Avaya Cloud Office make sense for every IP Office customer?

Avaya Cloud Office is a strong fit for some IP Office customers, particularly larger enterprises with existing Avaya Aura infrastructure who benefit from the hybrid Aura plus ACO deployment model. For smaller businesses moving to cloud for the first time, ACO is one option among several and worth evaluating alongside other cloud UCaaS platforms. Customers with compliance, reliability, or cost requirements that favor on-premise or private cloud deployments may also want to consider alternatives.

Q: What alternatives should Avaya IP Office customers evaluate?

Techmode’s platform, built on 3CX, is one option worth evaluating. It is available as an on-premise deployment, a cloud-hosted system on private AWS infrastructure, or a hybrid, with both perpetual capex and subscription opex licensing. Features include AI call summaries, native SMS and MMS, Microsoft Teams integration, mobile apps, and analytics. Techmode’s Premier Launch provides a dedicated project manager and U.S.-based concierge support throughout migration and beyond.
