Detailed Specifications
Yealink W77P - Ruggedized DECT IP Phone System
Overview :
The Yealink W77P is a professional ruggedized DECT IP phone system engineered for facility managers, logistics supervisors, and procurement teams in demanding industrial environments. It resolves voice communication breakdowns caused by dust, moisture, physical drops, and high background noise in warehouses, production floors, commercial kitchens, and outdoor loading bays.
The system comprises the W70B base station and the W57R rugged handset. The W57R carries an IP54 ingress protection rating and survives falls from up to 3.5 meters, with a durable rubber surface preventing slips, scratches, and everyday wear and tear. Acoustic performance includes HD voice, Opus codec support, and Flexible Noise Reduction (FNR) for crystal-clear calls in noisy conditions.
Deployment supports up to 10 registered W57R handsets per W70B base, up to 10 SIP accounts, and 20 simultaneous calls. Additional coverage extends via up to 6 RT30 DECT repeaters. Zero-touch provisioning via Yealink RPS and Boot mechanism simplifies mass deployment. Do not use this system with non-Yealink DECT devices, as interoperability is not supported. Home or light office environments do not require the ruggedised build of this system.
Key Features :
IP54 dust and splash proof handset
3.5m drop-resistant durable rubber surface
10-minute quick charge for 2 hours talk time
