Yeastar P-Series
Designed Migrated Managed by Liberty-i

More than a replacement PBX
Yeastar P-Series combines core call handling with Linkus unified communications, operator tools and optional customer-contact capabilities. Liberty-i turns those components into a service built around your numbers, users, sites and security requirements.
IVR, voicemail, call recording, routing, ring groups and business-hours control.
Supported web, desktop and mobile clients keep the business extension with the user.
Presence-led operator tools plus inbound queue panels, wallboards and reporting.
Messaging and Microsoft, CRM, helpdesk, directory or hospitality integration options.
One number across devices
Linkus can extend the phone system to supported browsers, Windows and macOS computers, iOS and Android devices. Users can work with presence, contacts, call history, voicemail and recordings from a consistent interface.

From answering calls to managing demand
P-Series can grow beyond standard telephony. Eligible editions and plans can introduce queue management, service-level visibility and omnichannel workflows without forcing every customer into the same licence profile.
Use IVR, queues, skills-based routing, priority and callback options to direct demand.
Give supervisors queue panels, wallboards, agent views and service-level information.
Use queue logs, recordings, disposition and performance reports where configured.
Eligible Enterprise and Ultimate plans can support central SMS and WhatsApp workflows.
Scope matters: contact-centre, messaging and integration availability depends on deployment edition, model, firmware, subscription plan and third-party service. Outbound contact-centre functionality is edition-specific. Liberty-i confirms each required capability before quotation.
