Hosted Cloud Phone Systems

Fully Managed Yeastar P-Series Cloud PBX | Scalable UCaaS for Businesses

In today’s hybrid and remote work environment, hosted cloud phone systems (also known as a Cloud Pbx Phone System, Cloud Based Phone System, or UCaaS) deliver enterprise-grade communication without hardware hassles. Your entire Cloud Phone Systems infrastructure runs on secure, redundant cloud servers—accessible from anywhere, on any device, with automatic updates, built-in high availability, and zero server maintenance.

At Hosted VoIP Services, we specialize in the Yeastar P-Series Cloud Edition—a powerful, full-featured Business Phone System that brings the same advanced capabilities of the on-premise P-Series to the cloud. Hosted by Yeastar (or self-hosted on your infrastructure via BYOI), it combines voice, video, messaging, contact center tools, and deep integrations into one seamless platform. No on-site appliance needed—just reliable, scalable business phone service that grows with you.
