Features & Services

ESI eCloud PBX™

ESI eCloud PBX™ is a fully hosted business phone system that replaces traditional on-premise phone hardware with a powerful, cloud-based solution.
It gives your organization the same advanced features used by large enterprises — auto attendants, call queues, voicemail-to-email, call recording, SMS, and more — all managed through a simple web dashboard.

With 99.999% uptime, U.S.-based support, and built-in disaster recovery, ESI eCloud keeps your business connected anywhere you work — desk, mobile, or remote — while eliminating the cost and complexity of maintaining physical phone systems.

Cloud PBX Integration with Microsoft Teams

While Teams is great for collaboration, ESI Cloud gives your business the phone system power Teams alone can’t — advanced call handling, voicemail-to-email, SMS, fax, and 99.999% uptime. It’s everything you already like about Teams, but business-grade and fully supported — enterprise-level call control and cloud simplicity.
