As businesses navigate the ever-evolving landscape of communication technology, Avaya’s recent announcement has sent ripples through the industry. Specifically, by June 30, 2025, Avaya will discontinue support for contact centers with fewer than 200 seats, while simultaneously scaling back operations in Europe and the Middle East. Consequently, this shift toward large enterprises (G1500) leaves small and medium-sized businesses (SMBs) and Avaya resellers searching for reliable alternatives. For those currently relying on Avaya, IP Office, or legacy business phones, now is the ideal moment to consider a phone system migration or, alternatively, a phone system upgrade to future-proof your communications.

Enter Yeastar, a global leader in unified communications (UC) and contact center solutions, which offers a robust alternative to Avaya IP Office. With a proven track record of seamless Avaya-to-Yeastar migrations, Phonewire delivers cutting-edge features, flexible pricing, and unmatched compatibility. As a result, Phonewire stands out as an ideal choice for both SMBs and enterprises. In this comprehensive guide, we’ll explore why Yeastar from Phonewire is the go-to solution for businesses facing Avaya’s strategic pivot, how it supports a smooth phone system migration, and, most importantly, why upgrading your business phones with Phonewire ensures long-term success.


Why Avaya’s Shift Signals the Need for a Phone System Upgrade

Avaya’s decision to focus on large enterprises and discontinue support for smaller contact centers reflects a broader trend in the communications industry. Specifically, as legacy systems like Avaya IP Office face reduced investment, SMBs increasingly risk being left with outdated business phones that lack modern features, scalability, and reliable support. Consequently, this situation creates a critical need for a phone system upgrade that aligns with today’s demands for flexibility, seamless integration, and cost-efficiency.

For Avaya resellers, the challenge is even more pronounced. In particular, with Avaya cutting ties with smaller customers, resellers must quickly pivot to a provider that prioritizes SMBs while still offering enterprise-grade capabilities. Fortunately, a phone system migration to a platform like Yeastar not only addresses these challenges but also opens new revenue streams through flexible pricing and recurring income models. Moreover, Yeastar’s robust solutions enable resellers to meet diverse customer needs effectively, ensuring long-term success in a shifting market.


The Case for Yeastar: A Superior Alternative to Avaya IP Office

Yeastar stands out as a leading choice for businesses and resellers seeking a reliable, feature-rich, and future-proof phone system upgrade. Specifically, the Yeastar Software Edition (PSE) combines advanced unified communications (UC) and contact center functionalities with seamless compatibility, making it a natural fit for those transitioning from Avaya IP Office. Here’s why Yeastar is the ideal solution for your phone system migration:

1. Outperforming Features Compared to Avaya IP Office

Yeastar offers a comprehensive suite of features that rival and often surpass those of Avaya IP Office and even Avaya Aura. These include:

  • Unified Communications (UC): Seamlessly integrate voice, video, messaging, and collaboration tools to streamline business operations.

  • Third-Party Integrations: Connect with CRMs, helpdesk software, and other business tools to enhance productivity.

Whether you’re a small business looking to modernize your business phones or an enterprise seeking scalable solutions, Yeastar’s feature set ensures you stay ahead of the curve.

2. Exceptional Compatibility with Avaya and TDM Devices

One of the biggest hurdles in a phone system migration is hardware compatibility.

Why SMBs Should Act Now: The Risks of Staying with Avaya IP Office

For small and medium-sized businesses (SMBs) currently using Avaya IP Office, the discontinuation of support for smaller contact centers serves as a critical wake-up call. Specifically, continuing to rely on an unsupported platform introduces several significant risks:

  • Firstly, lack of updates and security patches: Without ongoing support, Avaya IP Office users may encounter vulnerabilities that seriously compromise system security.
  • Secondly, limited scalability: Legacy business phones often struggle to accommodate business growth or seamlessly integrate with modern tools, hindering expansion.
  • Thirdly, increased maintenance costs: Aging systems frequently require costly repairs and inefficient workarounds to maintain basic functionality.
  • Additionaly, missed opportunities for innovation: By sticking with an outdated phone system, businesses inevitably miss out on advanced unified communications (UC) and contact center features that significantly enhance efficiency and customer satisfaction.

Fortunately, a phone system migration to Yeastar with the team from Phonewire effectively mitigates these risks, providing a modern, scalable, and secure platform that aligns perfectly with your business goals.
