Global enterprises need more than a communications platform. They need a technology partner capable of delivering reliable voice services, seamless collaboration, resilient infrastructure, regulatory compliance, and integrated customer experience solutions across multiple regions. CallTower is a global managed communications provider that helps enterprises consolidate unified communications, cloud voice, contact center, and collaboration under one strategic partnership. We combine industry-leading unified communications platforms like Microsoft Teams, Webex by Cisco, and Zoom with worldwide voice coverage, resilient infrastructure, centralized administration, and expert support. With services available in 80+ countries and support for more than one million users globally, CallTower helps global enterprises reduced complexity, improve reliability, and modernize communications at scale.
CallTower helps enterprises deploy, manage, and optimize cloud communications across multiple platforms and regions. Instead of forcing organizations into a single-vendor model, we support Microsoft Teams, Webex by Cisco, Zoom, and blended communications environments. This gives IT leaders flexibility while preserving centralized management, global voice consistency, reliable PSTN connectivity, and expert support.
CallTower strengthens communications continuity through a resilient global voice architecture designed to reduce single points of failure. For enterprises that depend on voice availability across locations, departments, and customer-facing teams, we combine geo-redundant infrastructure, carrier diversity, hosted session border controllers, and call routing tools that help maintain service during outages or network disruptions.
Enterprise communications platforms must support security, governance, data protection, and industry-specific compliance requirements. CallTower helps regulated organizations modernize unified communications and cloud voice while addressing compliance considerations across healthcare, government, financial services, retail, legal, and other sensitive environments. Relevant compliance frameworks include:
CallTower reduces communications complexity by bringing voice, unified communications, collaboration, contact center, mobility, analytics, and support into one managed services relationship. This approach helps enterprises avoid fragmented carrier contracts, disconnected administration portals, inconsistent support models, and unnecessary vendor sprawl. For IT, operations, and CX leaders, we create a simpler path to enterprise communications modernization.
CallTower's strength lies not only in delivering world-class communications platforms, but also in enabling organizations to pair those platforms with industry-leading contact center solutions like Genesys Cloud, Five9, Webex Contact Center, and Zoom Contact Center. By integrating UCaaS and CCaaS technologies, we help businesses create a unified environment that supports agents, employees, and customers alike. Professional services and long-term support further ensure these solutions continue delivering value after deployment.

CallTower brings these capabilities together across Microsoft Teams, Webex by Cisco, Zoom, Genesys, Five9, and other enterprise communications environments. By consolidating voice, collaboration, UCaaS, CCaaS, AI-enabled CX, and support into one managed services relationship, we help businesses simplify operations, protect continuity, improve customer and employee experiences, and scale communications worldwide with confidence.
