Deliver and Manage Cloud PBX Services
through a Central Platform

Yeastar offers a fully-managed turnkey solution to ensure fast time to market and high return on investments for service providers. Better yet, with the help of Yeastar Central Management (YCM), everything from service delivery to business operation is simplified in one place.

Simplify Service Delivery

Simplify Service Delivery

You have the flexibility to select preferred hosted servers closest to your customers. It only takes minutes, if not seconds, to create PBX with different capacities for your customers and the PBX will go live immediately. Your customers can then access and manage their phone systems right through the web. All PBX instances and customers are displayed in a list view and you can check the details of any of them.

Customize and Scale on Demand

Customize and Scale on Demand

It is clicks away to scale up and down services and upgrade subscription plans for various needs. There is literally no limit on instances and users, so whether there are a handful of customers or thousands, you can give them the freedom to grow at their own pace. This solution also enables you to create your own service packages, bundle IP phones and other hardware, and adds on SIP trunking and other services.

Real-time Performance Monitoring

Real-time Performance Monitoring

With YCM automatically monitoring the status of all your customers’ PBX instances, you get instant alerts when threats, security-related risks, or any other critical system issues occur, and can quickly diagnose and troubleshoot them before they hurt your bottom line. In addition, you can view the real-time status of all PBX instances at a glance in a single, customizable, widget-based dashboard.

Streamline Management in One Place

Streamline Management in One Place

YCM also serves as a consolidated management interface. For example, you can download firmware and backup files in one place, receive push notifications on new version releases, and view customers’ subscription status. YCM admins can add Colleague and Reseller accounts to co-manage the platform and customer devices, enabling granular administration by limiting permissions, grouping devices, etc.
