The Yeastar P-Series P550 is the ultimate telephony backbone for medium-sized enterprises, regional branch offices, and growing call centers. Moving away from restrictive subscription-based cloud platforms, this on-premise PBX appliance provides total ownership over your communication infrastructure. Housed in a durable 1U rackmount chassis, it centralizes voice, video, instant messaging, and advanced call handling into a single, highly secure network device capable of connecting your internal teams to the outside world seamlessly.
• Key Features
Built for Growing SMEs: Natively supports up to 50 internal extensions and handles up to 25 concurrent calls simultaneously, ensuring your phone lines never face bottlenecks during peak business hours.
Extensive Modular Expansion: The highly customizable motherboard accommodates multiple expansion modules, allowing you to deploy up to 8 FXS (Analog Phone) ports, 8 FXO (Analog Line) ports, or 8 BRI ports.
Quad-Cellular Fallback (3G/4G): Supports up to four distinct cellular SIM modules, providing an unbreakable disaster recovery lifeline for internet outages or enabling direct mobile routing to save on carrier costs.
Linkus UC Ecosystem: Transform your workforce into a truly mobile entity. The included Linkus Unified Communications app allows employees to make and receive corporate calls via iOS, Android, Mac, or Windows desktop software.
Advanced Call Center Suite: Elevate your customer service with built-in skills-based routing, SLA monitoring, live wallboards, call recording, and supervisor barge-in/whisper features.
Seamless Business Integration: Integrates flawlessly with top-tier business tools including Microsoft Teams, WhatsApp Business, Salesforce, HubSpot, and Zoho CRM.
• Performance / Technology
The P550 is powered by a rock-solid, proprietary Linux-based OS engineered for maximum uptime. Voice traffic is protected against eavesdropping and SIP hacking using military-grade TLS and SRTP encryption protocols. A built-in VPN server makes provisioning remote IP phones incredibly simple and highly secure, bypassing complex firewall configurations for remote employees.
• Design & Ergonomics
Unlike smaller desktop PBX models, the P550 features a professional 1U Rackmount form factor (34 x 21 x 4.4 cm), allowing it to bolt directly into standard 19-inch server racks alongside your existing networking switches and patch panels. It includes an integrated NFC tag on the chassis for rapid IP configuration via mobile phone, and a front-facing USB port for storing vast amounts of voicemails and call recordings on external flash drives or SSDs.
• Compatibility / Use Cases
The Yeastar P550 is universally compatible with standard SIP endpoints (such as Yealink, Fanvil, Grandstream, and Snom IP phones) and seamlessly bridges connections with major SIP trunk providers. It is the definitive communication infrastructure for mid-sized corporate offices, busy medical centers, automotive dealerships, and logistics hubs requiring robust, high-volume call handling.
• Why This Product Stands Out
The Yeastar P550 stands out by bridging the legacy hardware world with modern unified communications. It allows a business to retain their old copper Etisalat/Du analog lines via FXO modules, while simultaneously modernizing their internal office with video conferencing, mobile apps, and SIP routing—all without forcing the business to abandon their existing infrastructure overnight.
