Grandstream GRP2624 IP Phone, 8 Lines, 12 SIP, Wi-Fi 6, Bluetooth

Overview

Knowledge workers and team leads who live on headsets, and reception desks that may add key modules later, want one phone that does both. The Grandstream GRP2624 is an eight-line phone from the GRP2600 Professional range with 12 Session Initiation Protocol (SIP) accounts, a 2.8 inch colour screen and dual microphones. It adds Wi-Fi, Bluetooth and a USB headset port to Gigabit Power over Ethernet (PoE) ports, accepts up to four GBX20 expansion modules and comes with a 12 V adapter.

Is it right for you?

• Suits knowledge workers and team leads who use headsets heavily, with Bluetooth, USB and RJ9 options.
• Suits reception desks that may later add GBX20 modules for busy lamp field (BLF) monitoring.
• Works on Wi-Fi or cable, powered by PoE or the included adapter.
• Choose the GRP2634 instead if you want 10 fixed paper-label keys on the phone and do not need module support.

Key features

• 8 lines and 12 SIP accounts, so one handset can answer up to 12 numbers and hold eight calls.
• 2.8 inch colour screen (320 x 240) with 8 line keys, so you can see every active call.
• 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.
• Dedicated Transfer and Hold keys and a 2,000-entry phonebook.
• 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_B 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_B 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.

Before you buy

• Wi-Fi 6 applies to hardware version 5.0 and above; older stock may carry an earlier radio, so confirm the hardware version with us if Wi-Fi 6 matters to you.
• Power draw is 9.5 W at most on the adapter or 10.8 W on PoE, so check the switch’s PoE budget on a large roll-out.
• The GRP_WM_B wall mount bracket is sold separately and comes without screws or wall anchors.
• It is made for indoor desks, with an operating range of 0 to 40 °C.
