The Grandstream GRP2616 is the dual-screen executive model in Grandstream's GRP2600 carrier-grade family — a 6-line desk phone built for the people who handle the most calls and watch the most lines at once: receptionists, managers, dispatchers, and busy power users.

A 4.3-inch color LCD anchors the phone for the call in front of you, while a second 2.4-inch color screen sits beside the keypad and is dedicated to multi-purpose keys, so BLF status and speed dials stay visible without crowding the main display. The phone features 48 virtual multi-purpose keys, six line keys, and support for up to 16 SIP accounts, with 3-way audio conferencing built in.

Placement is flexible. Dual switched Gigabit Ethernet ports with integrated PoE run power and data over one cable in a standard wired install, while integrated dual-band Wi-Fi — Wi-Fi 6 (802.11a/b/g/n/ac/ax) on hardware version 5.0 and above — puts a phone where no network drop exists. Built-in Bluetooth pairs wireless headsets, and an RJ9 headset jack with EHS support covers wired headsets.

Calls are HD wideband on both the handset and the full-duplex speakerphone, with support for the major voice codecs including G.722 and Opus.

For administrators, the GRP2616 was designed for mass deployment: zero-touch provisioning and centralized configuration, monitoring, and firmware management through Grandstream's GDMS cloud platform, secure boot, dual firmware images, and encrypted data storage. The swappable faceplate lets a business or service provider put its own logo on every phone in the rollout.
