Insights

Professionals who manage high call volumes, such as executives, managers, and knowledge workers handling multiple projects, often need visibility into more lines and contacts than a basic desk phone can display. The GRP2616 addresses this with dual color LCD screens and 48 virtual multi-purpose keys, giving users at-a-glance access to line status, BLF monitoring, and speed dial without digging through menus.

Its integrated Wi-Fi 6 and Bluetooth also reflect the realities of modern offices, where not every desk has a convenient Ethernet drop and many users want to pair a wireless headset or mobile device directly to their desk phone, all while retaining the option of a simple, single-cable PoE installation when wired connectivity is preferred.
