The Yealink W77P is a high-performance, ruggedized SIP DECT cordless phone system built for professionals who work in challenging environments. Combining the IP54-rated W57R ruggedized handset with the W70B base station, the W77P is engineered to withstand drops from up to 3.5 meters, water splashes from any direction, and dust ingress — making it an ideal communication tool for manufacturing plants, warehouses, automotive shops, construction sites, and industrial facilities.
The system supports up to 10 W57R handsets, 10 SIP accounts, and 20 simultaneous calls per base station, with seamless scalability through up to 6 optional RT30 repeaters for extended indoor and outdoor coverage. The W57R handset features a 1.8" 128 x 160-pixel TFT color display, industry-leading battery life (up to 40 hours talk time / 575 hours standby), and a built-in vibration alarm that ensures no call is missed — even in the noisiest environments.
Equipped with Yealink's Noise Cancellation and FNR (Flexible Noise Reduction) technology, the W77P delivers crystal-clear voice in high-bandwidth or degraded network conditions.
