12 top contact center platforms of 2025
Which came first: the evolution of the contact center or the evolution of its supporting software? It's the old chicken-and-egg debate. Either way, AI is the catalyst.
Contact center software has existed since the dawn of digital contact centers decades ago. But in recent years, the contact center software industry has changed significantly. New types of technology, such as generative AI, have opened opportunities for developers to add powerful types of innovative contact center features to their platforms. And hyperscalers like Microsoft and Amazon have entered the space hoping to use their command of adjacent markets to claim a slice of the contact center software ecosystem.
All these developments prompt a reevaluation of modern contact center platform options. We identified the leading contact center platforms and summarized their most prominent features and drawbacks so businesses can make informed decisions. Consideration was given to research by IDC and independent user reviews appearing on TrustRadius and G2. Based on this analysis, we created an unranked, alphabetical list of 12 top platforms. The 12 software providers range in age from just a few years to a few decades, but the common thread is the integration of AI's evolving capabilities into their new and upgraded platforms.
1. Amazon Connect
Introduced by Amazon in 2017, Amazon Connect offers a centralized hub from which contact center agents can engage with customers across multiple channels, including voice, chat and messaging, and that can integrate with other Amazon products and services. In 2023, Amazon Connect incorporated several AI-based capabilities, such as support for creating virtual assistants.
2. Avaya
Software vendor Avaya traditionally focused its contact center software on on-premises hosting models, but it has recently expanded into cloud-based options that support public and private cloud deployments. Avaya provides all the core capabilities that businesses expect from a modern contact center platform as well as certain innovative features like AI-based virtual assistants.
3. CloudTalk
CloudTalk is most notable for its heavy focus on automation and analytics features designed to streamline contact center performance and increase operations efficiency. It also offers innovative AI-powered features, such as topic extraction, which automatically monitors conversational topics.
