Listen to this articleCourt Square Capital Partners acquired a majority stake in CallTower from BV Investment Partners, with BV and management retaining minority interests to fuel the next phase of global growth in managed cloud communications.
Court Square has acquired a majority stake in CallTower, a global provider of managed cloud communications, collaboration, and contact center solutions. The deal transfers ownership from BV Investment Partners, which had held a majority stake since late 2023. BV and CallTower’s management team are retaining a minority interest, aligning incentives for continued growth.
What is Court Square’s main focus?
Court Square Capital Partners is a leading U.S. middle market private equity firm with more than 40 years of experience partnering with management teams, founders, and families to build scalable businesses in sectors including technology and telecom. The firm focuses on market leaders and consolidators, emphasizing transformational growth through operational expertise, strategic add-ons, and capital deployment.
What is CallTower?
CallTower, founded in 2002 and headquartered in South Jordan, Utah (with additional offices in Rochester, New York; Montreal; London; and the Philippines), operates as a premier global cloud managed service provider. It specializes in complex, multi vendor, multi location environments, delivering Unified Communications as a Service (UCaaS), Contact Center as a Service (CCaaS), collaboration tools, and AI powered customer experience (CX) solutions. Key integrations include Microsoft Teams (Operator Connect, Direct Routing, GCC High), Webex by Cisco, Zoom Phone, Genesys Cloud CX, and Five9 Intelligent CX Platform, supported by more than 25 carriers and a proprietary integration platform called CallTower Connect. The company maintains 15 geo-redundant data centers and serves over 5,000 mid market and enterprise customers across more than 80 countries. Its differentiator is end to end managed and professional services that simplify deployment, ongoing management, analytics, and AI insights without requiring customers to become experts in multiple vendor ecosystems.
Under BV Investment Partners’ ownership starting in 2023, CallTower strengthened partnerships with major vendors, broadened distribution channels, accelerated bookings, expanded its geographic footprint, and enhanced its solution portfolio through the acquisition of Inoria (now providing consulting and professional services). This period positioned the company for its next phase of scaling.
The transaction is a classic secondary buyout in the tech enabled services space. Financial terms were not disclosed, which is standard for such private deals. Q Advisors acted as exclusive financial adviser to CallTower, and Ropes & Gray provided legal counsel. The structure, majority to Court Square with management and prior sponsor retaining minority stakes, facilitates continuity while injecting fresh capital and expertise.
Strategically, the acquisition aligns perfectly with both parties’ objectives. Court Square views CallTower as a best in class operator in an evolving market, citing its solution agnostic approach and proven ability to deliver reliable, tailored connectivity in hybrid and distributed work environments. Christopher Bloise, President and Managing Partner at Court Square, noted that CallTower has “set the standard for global cloud based communications, excelling in complex, multi vendor, and multi location environments.” The firm plans to support further innovation, channel expansion, and both organic and inorganic growth.
Bret England, President and CEO of CallTower, described the investment as a “transformative” milestone that will accelerate distribution channels, enhance proprietary technology, and extend modern platforms to more global enterprises. He emphasized continuity from the strong results achieved with BV while positioning CallTower to capitalize on the ongoing shift from legacy telephony and on-premises contact center systems. CallTower’s managed service model, powered by CallTower Connect and AI driven analytics, gives it a defensible edge as enterprises demand seamless, secure, and scalable communications without vendor lock-in.

The broader market context reinforces the deal’s timing. Demand for best of breed managed UCaaS and CCaaS platforms continues to surge as organizations navigate hybrid workforces, global operations, and AI integration in customer experience. CallTower’s focus on multi vendor orchestration, professional services, and 24/7 support addresses pain points that pure play vendors or basic cloud providers often cannot fully resolve for complex enterprises. The partnership enables accelerated international expansion, deeper AI/CX capabilities, and potential add-on acquisitions similar to Inoria, all while maintaining high service quality across 80+ countries.
The combination positions CallTower for accelerated leadership in the managed cloud communications sector. With Court Square’s middle market expertise and resources, the company is expected to pursue geographic growth, product innovation (particularly around AI and analytics), and strategic M&A to broaden its ecosystem. Management’s continued equity stake and the successful track record under BV suggest strong operational momentum. For Court Square, the investment adds a high growth, tech centric platform to its portfolio, consistent with its strategy of backing scalable leaders in communications and technology enabled services.
This acquisition represents a seamless handoff that builds on CallTower’s established foundation while unlocking the next stage of global scale and innovation in enterprise cloud communications.
