rewrite this title Big UC Update: CallTower – UC Today

Join Kieran Devlin from UC Today as he sits down with William Rubio, Chief Revenue Officer at CallTower, for a comprehensive “Big UC Update.” If you are navigating the complex world of Unified Communications or trying to figure out where AI actually fits into your business strategy, this conversation sets the stage for what’s working in 2026.

In this candid session, Kieran and William explore the “colossal” year CallTower has had and what lies ahead. They move beyond the standard corporate pitch to discuss the “CallTower Dedicated” culture and the specific technologies that are solving real-world headaches for international businesses today.

William breaks down CallTower’s philosophy of “enabling people to connect,” highlighting their agnostic approach to the big three – Microsoft, Cisco, and Zoom. The discussion gets specific on new innovations that are changing how employees communicate, shifting from general connectivity to seamless mobile integration.

Key discussion points include:

The “Dot Dot Dot” Ecosystem: How CallTower integrates over 30 applications – including CCaaS leaders like Genesys and Five9 – to create a turnkey solution that works identically in Germany, Brazil, or Canada.
Product Innovation: A look at their game-changing WhatsApp integration for Microsoft Teams and the Dual eSIM technology that allows seamless, compliant separation of business and personal calls on a single mobile device.
The AI Reality Check: William discusses the pressure boards are putting on CIOs to “implement AI,” and how CallTower is helping clients take a practical, “build the house before the city” approach to avoid failed, massive projects.
Market Outlook: Predictions on the inevitable consolidation of AI startups and the critical need for vendors to fill the education void for end-users.
