Cloud PBX powered by Yeastar P-Series — Official Yeastar Partner. 100% software solution with Linkus softphone on mobile, desktop and browser. No phone hardware required.

Why Yeastar P-Series Cloud

Smart-VoIP is a certified Yeastar Partner. We deliver the P-Series Cloud Edition — Yeastar’s flagship software-based unified communications platform, with over 450,000 deployments worldwide, hosted in our own infrastructure in Greece (GR-IX peering).

We sell a pure software service: monthly subscription, zero hardware investment, no on-site installation. Just user accounts and the Linkus app on devices you already own.

Linkus — Your office in one app

Every user gets access to Linkus UC Clients, Yeastar’s official softphone:

• Linkus Mobile (iOS / Android) — make and receive business calls from your personal mobile with your corporate number
• Linkus Desktop (Windows / macOS / Linux) — full-featured softphone with headset support
• Linkus Web Client — work from any browser, no installation needed

One account, everywhere: voice calls, chat, video meetings, file sharing, presence, voicemail-to-email. You don’t need IP phones — Linkus fully replaces the physical handset.

Compatibility (if you already have devices)
