The Grandstream GRP2650 is a professional 14-line desk phone in Grandstream's GRP carrier-grade family — built for receptionists, dispatchers, and busy professionals who need a lot of lines and contacts visible at once, on a phone that an IT team can roll out by the hundreds.

The 5-inch color LCD (1280 x 720) sits between banks of line keys and gives the phone 56 multi-purpose keys (MPKs) for line appearances, busy-lamp fields, and speed dials across 14 lines and 16 SIP accounts. For desks that outgrow even that, the GRP2650 supports Grandstream's GBX20 extension module — up to four modules, adding up to 160 contacts/extensions.

Placement is flexible. Dual switched Gigabit Ethernet ports with integrated PoE run power and data over a single cable in a standard wired install, while integrated dual-band Wi-Fi 6 (hardware version 5.0 and above) and Bluetooth put the phone where no network drop exists and pair wireless headsets cable-free. An RJ9 headset jack with EHS support covers Plantronics headsets, and a USB port supports USB headsets.

Calls are HD wideband on both the handset and the full-duplex speakerphone, with noise shield technology to keep background office noise out of the conversation, and 5-way audio conferencing is built in. A 12V power adapter is included in the box, so the phone works with or without a PoE switch port.

For administrators, the GRP2650 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.
