Arcstar UCaaS

Arcstar UCaaS was a cloud-based Unified Communications as a Service (UCaaS) solution developed by NTT Communications to facilitate seamless global collaboration. Built on the Arcstar Universal One VPN, it provided businesses with secure and reliable communication tools, including telephony, messaging, conferencing, and file sharing. The platform aimed to reduce total cost of ownership (TCO) while improving communication flexibility, making it a preferred choice for enterprises with distributed teams. However, the service ended sales on September 30, 2023, and is set to be fully discontinued on August 31, 2024, prompting businesses to seek alternative solutions. The user-friendly interface of Arcstar UCaaS enabled teams to efficiently switch between different communication features such as voice calls, instant messaging, video conferencing, and scheduling tools. With seamless cross-device compatibility, employees could access their communication suite from desktops, laptops, smartphones, or tablets. Integration with Cisco Unified Communications technology ensured high-quality audio and video conferencing experiences, while the platform’s secure cloud-based infrastructure allowed professionals to collaborate from anywhere. Businesses benefited from real-time presence indicators and instant notifications, streamlining workflow management and decision-making.
