Grandstream GRP2650 IP Phone, 14 Lines, 16 SIP, 5 Inch Colour, Wi-Fi 6

Overview

An executive, operator or busy reception desk that handles many lines needs a large, clear view of call status. The Grandstream GRP2650 is a 14-line phone with 16 Session Initiation Protocol (SIP) accounts and a 5 inch high-resolution colour screen that shows up to 56 virtual multi-purpose keys. It supports Wi-Fi, Bluetooth, USB headsets, Gigabit Power over Ethernet (PoE) and up to four GBX20 expansion modules, and comes with a 12 V adapter.

Is it right for you?

• Suits executives, operators and busy reception desks that handle many lines and want a large screen for call status and busy lamp field (BLF) monitoring.
• Suits headset users, with Bluetooth, USB and RJ9 options on the same phone.
• Can grow with GBX20 expansion modules.
• Choose the GRP2670 instead if you prefer a 7 inch touch screen.

Key features

• 14 lines and 16 SIP accounts, so one handset can answer up to 16 numbers and hold 14 calls.
• 5 inch colour screen (1280 x 720) whose 14 line keys page through up to 56 virtual multi-purpose keys, so a large team’s status is readable at a glance.
• Two switched Gigabit (10/100/1000 Mbps) network ports, so a computer connected through the phone keeps its full Gigabit link, with built-in PoE (IEEE 802.3af) so the phone can draw power from a PoE switch.
• Dual-band 2.4 and 5 GHz Wi-Fi 6 (802.11a/b/g/n/ac/ax) on hardware version 5.0 and above, so the phone can use the less crowded 5 GHz band in a busy office.
• Built-in Bluetooth, so a wireless headset can pair straight to the phone.
• High-definition (HD) wideband audio with dual microphones on the handset and speakerphone, and 5-way audio conferencing with Opus and G.722 codecs.
• 2,000-entry phonebook and a 2,000-record call log.
• Swappable faceplate, so you can add your company logo.
• Zero-touch cloud provisioning through Grandstream Device Management System (GDMS), with secure boot and encrypted data storage.

What else you need

• A SIP account for each line, from a phone system (IP PBX) in your building or in the cloud, or from a hosted voice over IP (VoIP) provider. The phone registers to any of them over standard SIP.
• Power from either the 12 V DC, 1 A adapter that comes with the phone or an IEEE 802.3af PoE switch port, so a desk with PoE needs no mains socket.
• A 2.4 or 5 GHz Wi-Fi network, or a network cable to the desk.
• Only if you want the phone on a wall, the GRP_WM_C wall mount bracket, sold separately.
• Only if you want a wired headset, one with an RJ9 plug; electronic hook switch (EHS) control works with Plantronics headsets, and the USB port takes Grandstream GUV series and other USB headsets.
• Only if you want more keys than the phone itself provides, GBX20 expansion modules: up to four can be chained for 160 extra contacts.

Installation

A desk phone is a plug-in job that an office IT person or phone installer can do: fit the handset cord, connect the network cable and the power adapter or a PoE switch port, then enter the SIP account details in the phone’s web interface. For a roll-out of many phones, an installer can push the settings through GDMS or TR-069 instead.

The supplied desk stand gives two desk angles.

For wall use, fit the GRP_WM_C bracket. Screws and wall anchors are not included with the bracket, so match them to your wall. Reverse the hookswitch tab under the handset rest so the handset stays put when the phone is upright.

Software and licences

GDMS cloud provisioning and TR-069 let an installer or IT team configure, monitor and update phones centrally, and the web interface covers a single phone. Grandstream’s Click2Dial browser extension places calls from a computer.
