Constellation ShortList™ Contact Center as a Service (CCaaS)

Contact center solutions have largely stayed the course in terms of functionality, enabling organizations to route, address, and resolve inbound customer interactions and engagements. Contact center as a service (CCaaS) shifted this critical frontline of customer experience (CX) to the cloud, with the promise of scalable infrastructure and a flexible toolset to modernize a contact center that has become more complex. But in the age of AI, experienced teams expect more: more engagement, more channels, more connections, and more cost savings to materially impact the bottom line. What has emerged is a new breed of CCaaS tools that can offer traditional inbound engagement interactions with fully integrated outbound dialing and multi-channel digital communications, predictive dialers, proactive cross-channel messaging and engagement, and more robust collaboration and workforce management tools.

While 2025 saw a boom in generative AI tools, 2026 will be the year of the autonomous enterprise with workflows and agentic capabilities that automate common operations. Agents and supervisors now expect smart co-pilots at the ready to help guide customers to positive outcomes. AI-powered tools, including smart routing, intelligent workforce planning, agent assist, sentiment analysis, chatbots, Interactive Virtual Agents (IVA), data management, conversational intelligence, and process automation, have become core considerations in provider selection. Customers now expect smarter self-service experiences, allowing them to manage more of their own self-determined experiences in the moments and channels of their choice. And increasingly, everyone expects voice to be an interface, not just a channel. 

2026 will bring more AI-driven change, with more robust analytics, experience augmentation through real-time, personalized content creation, and the reality of cross-functional CX operations coming into view. But the AI proof-of-concept experiments initiated years earlier continue to struggle, often failing to become fully operationalized projects, adding pressure on COOs and Chief Experience Officers to advance their AI initiatives and budgets in the contact center. While CX leaders initially laid blame for this lack of AI scalability on an enterprise and agent aversion to change or a lack of AI readiness, it has become clear that legacy systems and a lack of meaningful, renewable data are central culprits in the lag in adoption and acceleration. This is especially true of buyers still pushing their cloud shift agendas who are now being asked by the Board to showcase how AI will be deployed as a business transformation and differentiation tool. The pressure to perform will be intense, and AI will increase scrutiny of the value being delivered. Contact center leaders, once convinced that AI and the cloud could eliminate headcount, are reinvesting in people who expect more robust, usable AI-powered tools. This will add pressure to CCaaS vendors to deliver AI capabilities focused on new key performance indicators and business outcomes as strategies shift away from the days of containment and deflection and more earnestly into AI empowered continuous relationship building.

Constellation Research has excluded solutions where communications channels like voice and telephony are delivered via partnership, leading to worthy solutions like Google Cloud CCAI Platform (partnering with UJET) and Zendesk CCaaS (built on Amazon Connect) just outside of this year’s consideration
