The module magic does not end here; in Yeastar S-Series, SIP users and concurrent calls are also expandable with suitable modules, allowing your telephone system to truly grow with your business.

Don’t be surprised to learn that some features are also modular as they can be separately installed and uninstalled in App Center. And there is no need to upgrade firmware when new features are added, as they can also be managed in App Center.

Curious about configuration and maintenance? Everything can be configured if you log in the graphical UI on any Internet-enabled device. Yeastar S-Series introduces sleek and intuitive Metro UI which allows users to configure PBX settings in a familiar Windows PC style with desktop, taskbar, minimize/maximize/close button and everything.

No Licensing Fees = New Features+ Existing Rich Features

Hundreds of practical features beneficial to businesses are packed into Yeastar S-Series without extra licensing fees, providing a dramatically lower total cost of ownership.

Call Recording

All models of Yeastar S-Series support
Automatic Call Recording to monitor the conversation for various purposes
required by your business. All the recordings can be inquired, replayed,
and managed by administrator or by
permitted individuals on the Web GUI.

Event Center

17 kinds of events are recorded in
Event Center. When abnormalities like
SIP trunk registration failure, user login
failure, network attack, and system
overload occur, administrator will be
notified by Email, phone call or SMS.

SIP Forking

Yeastar S-Series is able to support SIP
forking feature and register one
extension number to multiple SIP
endpoints. With SIP forking, your desk
phone ring and mobile softphone can
ring at the same time, and you will be
able to take calls from either device.

Visual Status Monitor

Yeastar S-Series provides real-time
graphical monitoring for PBX status
like extensions, trunks, concurrent
calls, and resources usage like CPU,
memory, and Ethernet rate.

AutoClip

Never miss a returned call! The AutoCLIP feature will store information about outgoing calls in the AutoCLIP list and match a returned call with the original caller. In other words, when a person calls back, the call will be routed to the original extension automatically if you enable AutoCLIP feature. Free the front desk from the hassles of constantly asking who called who question.
