Grandstream WP836
The cordless phone for hard places. It's sealed against water and dust, can be washed down, survives a 2-meter drop, and watches out for the person carrying it.
- Set up for WaveCore PBX before it ships. Give us your Wi-Fi name and password and it arrives ready to ring.
- Works from home, too. Join it to the Wi-Fi at home or at another office and it's still your extension on your office system.
- IP67 and IP69K. Waterproof and dustproof, and it stands up to high-pressure, high-temperature wash-down and cleaning chemicals.
- Drop-safe to 2 meters. Built for warehouses, kitchens, job sites and the outdoors.
- Lone-worker alarms. Man-down, no-movement and running alarms, plus a push-button alarm, so a fall or emergency calls for help on its own.
- Your extension, anywhere on site. Wi-Fi 6 with fast roaming (802.11k/r/v) and up to 10 hours of talk time.

Man-down, no-movement, running and ambient-sound alarms, plus a push-button alarm, for people working alone.
Push-to-talk and paging
