Innovation by software providers is outpacing enterprises' ability to adapt but provides opportunity to modernize customer experiences, new research says

The evolution of AI in contact centers and enterprise operations is disrupting customer processes and may change the outcomes of software investments, according to new research from global AI-centered technology research and advisory firm Information Services Group (ISG) (Nasdaq: III).

The ISG Buyers Guides™ for Contact Centers, produced by ISG Software Research, provide the rankings and ratings of 40 software providers across four software categories and three vertical industries, assessing products that support automated and intelligent contact centers. The research finds that many enterprises are overhauling contact centers that have remained largely unchanged for decades. Using new tools derived from conversational and generative AI, they are expanding opportunities for customers to have intelligent self-service interactions while enabling agents to more effectively engage with customers.

"Contact centers have seen more innovation in the past three years than at any other time in their history," said Keith Dawson, director of research, Customer Experience, ISG Software Research. "By 2027, more than three-quarters of them will include multiple GenAI applications in their service processes."

The transformation of contact centers is being fueled by AI, cloud technology and new market entrants, the research finds. Beyond the core functions of routing and workforce management, today's platforms are defined by analytics, automation, conversational AI and integration with customer relationship management (CRM) and customer experience (CX) systems. However, enterprises first and foremost are looking for ease of use, interoperability, clear ROI, and proven AI results from contact center software, ISG research finds. To succeed, platforms must combine rock-solid reliability with advanced AI-driven features that improve efficiency and elevate the customer experience.

Most current software configurations are deployed in the cloud in the form of contact center as a service (CCaaS), the research finds. They have turned the routing engine at the heart of contact center infrastructure into a commodity. As a result, enterprises have been able to build contact center systems based on whichever component is most important to them, but the cost and maintenance requirements are significant, and contact center suites with platforms and tools are readily available today.

Enterprises are now most often sourcing contact center technology from as few providers as possible and prefer suites for simplicity of administration, the research finds. Most companies evaluating products today have not bought contact center systems since before the pandemic and are facing a world of new capabilities with AI that did not exist five years ago. ISG advises buyers to focus on customer experience. Customer interactions require not just routing and self-service but the foundation for agents and knowledge to guide engagements toward mutually beneficial resolutions and outcomes.

For its 2025 Buyers Guides™ for Contact Centers, ISG evaluated software providers across four software categories — Contact Centers, Agent Management, Customer Interaction Analytics and Intelligent Self-Service — and three vertical industries: Contact Centers for Healthcare, Contact Centers for Insurance and Contact Centers for Retail. ISG produced a separate Buyers Guide for each category and industry. A total of 40 providers were assessed: 8x8, Aircall, Alvaria, Aspect, Avaya, AWS, Calabrio, CallMiner, Cisco, Content Guru, Dialpad, Eleveo, Emplifi, Enghouse Interactive, evaluagent, Exotel, Five9, Genesys, GoTo, Intradiem, LivePerson, Microsoft, Mitel, net2phone, Nextiva, NiCE, Odigo, RingCentral, Salesforce, Sinch, Sprinklr, Talkdesk, Twilio, UJET, Verint, Vonage, XTIUM, Zendesk, Zoho and Zoom.

ISG Software Research rates software providers in seven evaluation categories. Five are related to product experience, covering the software's overall capabilities and the adaptability, manageability, reliability and usability underlying them. Two are related to customer experience: validation and total cost of ownership and return on investment (TCO/ROI). Providers ranked in the top three for each evaluation category are named as Leaders. Within each platform category, those with the most Leader rankings are named as Overall Leaders.

The Overall Leaders of the 2025 Buyers Guides for Contact Centers were the following:
