More product details
The Grandstream WP816 is a cordless Wi-Fi IP phone designed for environments where desk phones are impractical but cellular coverage is unreliable. It is a strong fit for warehouse floors, retail sales floors, hospital corridors, or any setting where staff need to stay reachable while moving around a building. The integrated Wi-Fi 6 and roaming support mean it can follow a user across a properly configured wireless network without dropping calls, which is a genuine advantage in larger office or industrial spaces. The device pairs naturally with a hosted PBX or an on-premise SIP server, and its push-to-talk button makes it useful for intercom-style communication among teams. A practical tradeoff is the 6-hour talk time; heavy users will need to dock the phone between shifts, and the reliance on Wi-Fi means call quality depends on network coverage and congestion, not on a dedicated base station. For a small retail shop with a single access point, the roaming features are overkill, but for a multi-floor GTA office with a well-tuned Wi-Fi network, the WP816 can replace a traditional DECT system without requiring dedicated base stations or repeaters.
