Grandstream GRP2650 Carrier-Grade IP Phone

The Grandstream GRP2650 is the largest conventional-key phone in the professional GRP range. Fourteen line keys and fifty-six virtual multi-purpose key positions are driven by a 5-inch 1280 × 720 display — a genuinely high-resolution screen by desk-phone standards, which makes labels, directories and call lists far easier to read than the 480 × 272 panels used further down the range.

That combination is aimed at operators, coordinators and executive support staff who need a real console rather than a desk phone with a few extra keys. Six programmable soft keys, 5-way conferencing and noise shield handle the call work; dual-band Wi-Fi 6, Bluetooth and USB headset support handle the connectivity. Despite the size, it draws a maximum of 6.2W, so it sits comfortably on an 802.3af PoE port.

Ideal for

• Switchboard and operator positions in larger organisations
• Executive assistants supporting several senior managers
• Service desks and dispatch teams monitoring many extensions
• Hotel and hospital front-of-house positions
• Users who struggle with small phone displays
• Sites wanting console capability without a separate expansion module

Key features

• Fourteen line keys with 16 SIP accounts — full console line capacity in one unit
• Fifty-six virtual multi-purpose key positions — extensive BLF and speed-dial coverage
• 5-inch 1280 × 720 colour display — the highest-resolution screen in the professional GRP range
• Six programmable soft keys — XML context-sensitive functions that follow the call state
• 5-way audio conferencing — multi-party calls without involving the PBX bridge
• Noise shield technology — suppresses background noise on speakerphone calls
• Integrated dual-band Wi-Fi 6 — 802.11a/b/g/n/ac/ax on 2.4GHz and 5GHz
• Integrated Bluetooth — wireless headsets and mobile contact syncing
• USB and RJ9 EHS headset support — works with almost any headset a user brings
• 6.2W maximum draw — a large phone that still sits comfortably on 802.3af PoE
