More product details
The Grandstream GRP2602W is a two-line IP phone built for small-to-medium business environments where wired Ethernet isn't always available or convenient. Its integrated dual-band Wi-Fi (2.4 GHz and 5 GHz) makes it a solid choice for desk workers in shared offices, retail counters, or home offices where running a cable is impractical. The phone also includes dual switched 10/100 Mbps Ethernet ports, so you can still connect it via cable when a port is nearby, and even daisy-chain a computer. For a business relying on a hosted VoIP provider, this phone can be provisioned and managed remotely through Grandstream's GDMS platform, simplifying deployment across a team. The HD audio and noise-shield technology help keep calls clear in open-plan settings, though the two-line limit means it won't suit a high-volume call center or a user who needs multiple simultaneous conversations. It supports Electronic Hook Switch (EHS) with common headset brands, which is practical for professionals who take a lot of calls hands-free. In a Canadian context, this phone works well with most SIP-based providers in the GTA, provided the WiFi network has sufficient coverage and bandwidth. The lack of PoE support (due to the WiFi model) means you'll need a nearby power outlet or a USB power adapter for some setups. While the display is small and monochrome, it's sufficient for call status and soft keys, and the phone's overall build quality suits a busy office environment.
