Work doesn't stop at the desk.
With Grandstream Wi-Fi cordless phones, your team stays connected across warehouses, retail floors, offices and large facilities — without being tied to a fixed location. Designed for mobility, durability and crystal-clear voice quality, the WP Series keeps your business moving from any corner of your premises.
Built for mobility. Built for business.
Designed for environments where staff need to roam — warehouses, retail floors, hospitality venues, healthcare, multi-floor offices.
True Mobility
Stay connected across the whole workplace. Handsets roam seamlessly between access points — warehouse, floor, between rooms.
HD Audio & Dual-MIC
Every model features HD voice with dual-MIC and echo cancellation. Selected models add AI noise reduction.
Seamless Roaming
Fast roaming (802.11k/r/v) on most models — calls aren't dropped when moving between access points.
Flexible Deployment
Works with your existing Wi-Fi network — no proprietary base stations. Compatible with BizTel, iPECS Cloud, all standard SIP platforms.
Long Battery Life
From 6 hours on entry models to 20 hours on the WP856. Standby up to 240 hours on selected models.
Scalable Solutions
Single handset for a small office or fleet for a large enterprise. Central provisioning via Grandstream GDMS.
