Here’s what it delivers:

  • Hosted in the Cloud: Your entire phone system runs securely in the cloud (no servers to maintain, no downtime to manage).
  • VoIP Business Phone System: Calls travel over the internet for crisp audio quality and consistent reliability.
  • Unified Communications as a Service (UCaaS): Combine voice, video, messaging, and conferencing in one platform for simpler collaboration.
  • Microsoft Teams Integration: Connect your 8x8 system with Teams for seamless internal and external communication.
  • Scalable & Secure: Easily add users, devices, or locations while maintaining enterprise-grade encryption and compliance.

A modern, cloud-based approach simplifies communication and supports hybrid work. Your business stays connected without the cost or complexity of traditional phone systems.

What is a Cloud-Based Business Phone System?

Cloud migration services involve moving your organization’s applications, servers, and data from on-premises or legacy systems into modern cloud environments. This process improves flexibility, enhances security, and reduces the costs of managing physical infrastructure. thirtyone3 technology’s cloud migration services are built around precision and planning. We assess every workload, dependency, and compliance requirement to ensure your transition is seamless and your data integrity remains intact.

What's Included

A cloud-based business phone system uses internet connectivity instead of traditional phone lines to make and receive calls. It allows your team to communicate from anywhere (through desk phones, computers, or mobile devices) without complex infrastructure or expensive maintenance.

With VoIP technology and providers like 8x8, calls are routed securely through the cloud, giving businesses reliable service, clear audio, and easy scalability. Features like auto-attendants, call forwarding, conferencing, and analytics are included out of the box, helping small and midsize businesses operate like large enterprises.

Unlike legacy PBX systems, cloud-based phone systems grow with your organization; offering flexibility, lower costs, and better performance whether you have five users or five hundred.
