Linkus is Yeastar’s unified communications (UC) client — the application that connects users to their Yeastar PBX system from a desktop computer, mobile phone, or web browser. It is included at no additional cost across all Yeastar P-Series licence tiers, which makes it a straightforward inclusion in any Yeastar deployment and a useful part of the reseller proposition when competing against platforms that charge separately for mobile or desktop clients.
What Linkus Includes
Linkus is available in three versions that cover different user scenarios:
- Linkus Desktop Client (Windows and macOS): Full PBX functionality on a laptop or desktop — calls, call transfer, voicemail access, internal messaging between colleagues, and presence indicators showing who is available. Suited to office-based staff who prefer a softphone to a physical desk phone.
- Linkus Mobile Client (iOS and Android): Extends the office phone system to staff mobile phones. Push notifications ensure incoming calls wake the device reliably — a common failure point of less mature mobile softphones. Staff can receive calls on their office extension without giving clients or suppliers a personal mobile number.
- Linkus Web Client: Browser-based access to the same core functionality. Useful for users on managed devices where installing software is restricted, or for hot-desking environments where a persistent app installation is not practical.
Microsoft Teams Integration
Yeastar P-Series includes native Microsoft Teams integration, allowing Teams users to make and receive PBX calls directly within the Teams interface. This is relevant for clients who are invested in the Microsoft 365 ecosystem and want to avoid running a separate communications application alongside Teams. The integration is built into Yeastar natively — it does not require a third-party connector or additional Microsoft licensing.
This is an increasingly common question in client conversations as Teams adoption has grown across the UK SME market. Having a clear answer — native integration, no extra cost, configured by X2 as part of deployment — simplifies that part of the sales conversation considerably.
How to Position Linkus in Client Conversations
Linkus addresses a question most SME clients are asking implicitly: can my staff work properly from anywhere using the office phone system? For clients on legacy ISDN systems, the contrast is significant. They are accustomed to desk phones only, with no remote working capability at the telephony level. Linkus allows their existing phone numbers and extensions to follow staff wherever they work — home, client sites, on the road — without complexity.
For clients comparing Yeastar against competitors: Linkus is included in the base Yeastar P-Series licence. Some competing platforms charge separately for mobile clients or restrict them to higher licence tiers. The inclusive positioning is a clean commercial point in the initial proposal.
What X2 Handles
As part of any Yeastar deployment, X2 configures Linkus alongside the rest of the system. User provisioning, push notification setup, and QR code generation for rapid mobile deployment are all handled by our engineering team. You present the capability to the client; we handle the technical configuration.
