SKU : YEALINK SIP-T88W PRO
Android 13
TEE hardware encryption solution
7 inch (1024 x 600) capacitive adjustable touch screen
Supports Yealink Bluetooth Handset BTH88
Optimal HD audio, Yealink Noise Proof Technology

The Yealink SIP-T88W Pro sits at the pinnacle of Yealink’s next-generation smart business phone lineup. Powered by Android 13 and anchored by a tilting 7-inch 1024×600 capacitive touchscreen, it combines the simplicity of a traditional PBX desk phone with the speed and third-party app extensibility of a smart tablet. Unlike the standard corded T88W, the Pro edition includes the BTH88 Wireless Bluetooth Handset right in the box—giving executives untethered freedom to pace the office while maintaining crystal-clear HD audio.
• Performance / Technology
Engineered on Android 13 with Yealink’s "Three Rings of Security" architecture, the SIP-T88W Pro utilizes a Trusted Execution Environment (TEE) for hardware-level encryption, secure boot verification, TLS 1.3, SRTP, and WPA3 wireless security. Its integrated Wi-Fi 6 radio ensures low-latency VoIP packet prioritization in dense wireless environments, while Dual-Port Gigabit Ethernet with IEEE 802.3af PoE provides full 1Gbps wired workstation passthrough.
• Design & Ergonomics
Designed for prestigious executive suites, the SIP-T88W Pro features an ultra-slim silhouette, an adjustable floating-style 7-inch display, and a wear-free magnetic Hall-effect hookswitch. The user interface includes native Light/Dark Theme switching and Accessibility Mode for effortless daily visibility, while the cordless BTH88 handset eliminates tangled desk cords.
• Compatibility / Use Cases
The SIP-T88W Pro integrates seamlessly with major on-premise and cloud SIP platforms—including 3CX, Yeastar P-Series, Grandstream UCM, Asterisk, FreePBX, and Broadsoft—and supports centralized zero-touch deployment via the Yealink Device Management Platform (YDMP/YMCS). In addition to standard PBX calling, it supports IP intercom/doorphone video preview and one-button door release, making it ideal for CEO offices, VIP reception desks, clinics, and law firms.
• Why This Product Stands Out
While standard executive IP phones tether you to your desk with a coiled cord and require external USB dongles for Wi-Fi or Bluetooth, the Yealink SIP-T88W Pro delivers an all-in-one wireless powerhouse. By combining built-in Wi-Fi 6, Android 13, a tilting 1024×600 touchscreen, and the cordless BTH88 Bluetooth Handset, it offers the most versatile voice-first executive experience in the Yealink portfolio.
