Description
The WP816 is Grandstream's entry-level cordless Wi-Fi IP phone. It registers two SIP accounts on two lines and delivers HD voice thanks to its two microphones, echo cancellation and Noise Shield technology that blocks background noise. Its dual-band 802.11 a/b/g/n/ac/ax Wi-Fi, with an efficient antenna and advanced roaming, keeps the call alive when the user moves to another access point. Built-in Bluetooth allows a wireless headset, and a 3.5 mm jack takes a wired one. A configurable key serves as push-to-talk, while an emergency button and an accelerometer complete the safety functions. The 1,500 mAh battery gives 6 hours of talk time and 120 hours of standby, and recharges quickly through the USB-C port.

Use and tips
The WP816 suits staff who must stay reachable while moving around a Wi-Fi covered site: sales assistants, front desk staff, maintenance technicians, small warehouse teams. It registers on the IP PBX like a regular SIP phone and avoids installing a DECT base station. Ensure gap-free Wi-Fi coverage and fast roaming between access points. If you need more battery life or three SIP accounts, choose the WP826; for a rugged casing with lone worker alarms, the WP836.
