Yeastar’s latest P-Series update brings a fresh wave of innovation to business communications — and it’s packed with smart, user-driven enhancements. From tailored presence statuses and hands-free Linkus CarPlay support to seamless S-Series migrations and expanded language options, this firmware release is designed to simplify workflows and keep teams connected, wherever they are. Whether you’re managing a growing business or supporting a hybrid workforce, these new features offer greater flexibility, mobility, and control.
🌟 What’s New in the June 2025 P-Series Update?
✅ Presence Customisation – Smarter Status Management
Now you can tailor user presence settings to reflect real-time availability with greater accuracy. The update allows you to:
-
Modify the default six presence statuses or create custom ones (e.g., “In Training”, “On-Site Visit”).
-
Add unique icons and names to suit your team structure.
-
Keep remote and hybrid teams in sync with live, synced updates across Linkus clients.
Why it matters: Clearer communication with fewer messages and less confusion — everyone knows who’s available and why at a glance.


🚘 Linkus CarPlay Support – Stay Connected on the Go
The Linkus Mobile Client now supports Apple CarPlay, allowing you to handle calls safely while driving:
-
Answer or reject calls from your car display.
-
Use Siri to dial contacts, check voicemail, and more — hands-free.
-
Navigate contacts and messages easily via the CarPlay interface.
Pro Tip: Just connect your phone via Bluetooth or USB/Type-C, launch Linkus, and drive smarter.
