“Enterprises are looking for practical AI that improves customer experience without forcing them to start over,” said Joe Bigio, Senior Vice President of CCaaS, CX, and AI Solutions at CallTower. “This partnership expands CallTower’s AI capabilities with solutions that help organizations automate more effectively, support agents more intelligently, and deliver stronger multilingual experiences across their contact centers.”

“What makes this partnership especially valuable is how well SESTEK’s technology fits into the environments customers already have in place,” said Alain LeBrasseur, CCaaS, AI, and CX Product Owner at CallTower. “It gives us the ability to bring advanced conversational AI, analytics, biometrics, and translation into existing CX strategies while pairing those tools with the design, implementation, and support needed to make them effective in real-world operations.”

A Shared Vision for Cloud-Agnostic CX Evolution

With over two decades of dedicated R&D in conversational technologies, SESTEK supports more than 700 enterprise organizations spanning 20 countries. Its strong footprint across heavily regulated and high-volume sectors-including banking, insurance, telecommunications, retail, and Business Process Outsourcing (BPO)-validates the scalability of its software.

SESTEK’s cloud-agnostic architecture and proprietary AI models match perfectly with CallTower’s philosophy of delivering highly adaptable communication systems, allowing businesses to roll out cross-channel AI without introducing structural complexity.

“At SESTEK, we believe the future of customer experience isn’t defined by a single AI capability, it’s created when automation, human expertise, and conversational intelligence continuously improve one another,” said Yalim Eristiren, Managing Director, North America at SESTEK. “Our partnership with CallTower enables organizations to bring that vision to life by delivering AI that not only automates customer interactions, but also measures performance, empowers agents, and makes every interaction better than the last.”
