Grandstream GRP2624 8-Line Carrier-Grade IP Phone

The Grandstream GRP2624 8-Line Carrier-Grade IP Phone provides reliable voice service for modern businesses. It combines clear sound, strong security, easy setup, and advanced call tools in one smart desk phone.

The phone supports 8 line keys and up to 12 SIP accounts. Therefore, users can manage several business lines, extensions, or departments from one device. This makes it useful for staff who receive many calls during the working day.

In addition, the GRP2624 features a clear 2.8-inch colour LCD screen. The display gives quick access to contacts, call history, voicemail, menus, and line status. As a result, users can find key phone tools without moving through long menus.

The GRP2624 also supports zero-touch setup and remote control through Grandstream Device Management System. Consequently, IT teams can install and manage many phones with less work.

Supports Eight Lines and Twelve SIP Accounts

The Grandstream GRP2624 supports 8 lines and up to 12 SIP accounts. Therefore, one user can handle several numbers or extensions from a single desk phone.

For example, a receptionist can manage calls for sales, support, accounts, and other departments. Meanwhile, managers can use different SIP accounts for separate offices or business units.

The phone also offers four soft keys and several set function keys. As a result, users can place calls on hold, transfer callers, mute the microphone, check messages, and use the speakerphone with ease.

This line capacity makes the phone ideal for:

• Reception areas
• Front desks
• Customer care teams
• Sales departments
• Office managers
• Executive users
• Multi-branch businesses

Clear 2.8-Inch Colour Display

The GRP2624 includes a 2.8-inch, 320 × 240 colour LCD screen. Therefore, call details and phone menus remain clear and easy to read.

Users can quickly view:

• Incoming caller details
• Active lines
• Call history
• Contact lists
• Voicemail alerts
• Phone settings
• Network details
• SIP account status

In addition, the phone has a simple menu system. As a result, new users can learn how to use it quickly. The clear display also helps reduce errors when handling several calls at once.

Built-In Dual-Band Wi-Fi 6

The Grandstream GRP2624 supports integrated dual-band Wi-Fi 6 on hardware version 5.0 and above. It works on both the 2.4GHz and 5GHz Wi-Fi bands.

Therefore, businesses can place the phone in areas without a nearby network cable. This is useful when moving desks, opening temporary offices, or adding phones in rented work areas.

Wi-Fi 6 can also provide better network use where many devices connect at the same time. As a result, the phone can maintain a more stable wireless link in busy office spaces.

However, Wi-Fi 6 support depends on the hardware version. Therefore, buyers should confirm that the supplied unit is hardware version 5.0 or newer.

Integrated Bluetooth Support

The GRP2624 also includes built-in Bluetooth.

Therefore, users can connect supported wireless headsets for hands-free calling. This allows employees to move around the desk while staying on a call.

Bluetooth can also support contact and calendar syncing with compatible devices. As a result, users can access more information directly from the phone.

This feature is useful for receptionists, call agents, office managers, and other users who spend long periods on calls. In addition, it helps keep the desk neat by reducing headset cables.

Full HD Audio for Clear Calls

The Grandstream GRP2624 delivers full HD audio through both the handset and speakerphone. Therefore, voices sound clearer and more natural.

The phone supports wideband audio codecs such as G.722 and Opus. In addition, it uses a full-duplex speakerphone, which allows both callers to speak at the same time.

The GRP2624 also includes Noise Shield Technology. This feature helps lower unwanted sound from the surrounding area. As a result, calls remain easier to hear in open offices and busy workspaces.

Clear sound can reduce repeated questions and misunderstandings. Therefore, it helps staff serve customers more quickly and professionally.

Dual Gigabit Ethernet Ports

The GRP2624 has two auto-sensing Gigabit Ethernet ports.

One port connects the phone to the office network. Meanwhile, the second port can connect a nearby computer. Therefore, the phone and computer can share one network point.

Gigabit ports support speeds of 10, 100, and 1000Mbps. As a result, the connected computer can still enjoy fast network access.

This design is useful in offices with limited wall network points. In addition, it can reduce the need for extra network cabling at each desk.

Power over Ethernet Support

The Grandstream GRP2624 supports IEEE 802.3af Power over Ethernet.

PoE allows one network cable to carry both power and data. Therefore, the phone does not need a separate power cable when connected to a suitable PoE switch.

This setup helps reduce cable clutter. In addition, it makes desk installation faster and cleaner.

A PoE phone system can also connect to a central UPS through the network switch. As a result, the phones may continue working during short power cuts, depending on the UPS capacity and setup.

The package also includes a 12V power adapter. Therefore, the phone can still operate where a PoE network is not available.

Five-Way Audio Conferencing

The GRP2624 supports 5-way voice conferencing.

Therefore, users can bring several callers into one meeting without using a separate conference phone. This is useful for team updates, customer talks, supplier calls, and remote planning.

The user can place calls on hold and then join them into one voice meeting. As a result, teams can make decisions faster without arranging another meeting platform.

This feature is especially helpful for managers, sales teams, service desks, and staff working across different locations.

GBX20 Extension Module Support

The Grandstream GRP2624 works with the optional GBX20 extension module.

Each GBX20 module supports up to 40 contacts or extensions. In addition, the phone can connect to as many as four modules. Therefore, users can manage up to 160 contacts or extensions through the added modules.

This makes the GRP2624 suitable for receptionists and operators who need to watch many extensions. Users can also set keys for speed dial, call transfer, and line status.

As a result, calls can reach the correct staff member more quickly. The extension module is sold separately.

Headset Connection Options

The GRP2624 provides several headset choices.

It includes an RJ9 headset port with EHS support for selected Plantronics headsets. In addition, its USB port supports Grandstream GUV Series headsets and other supported USB models.

Built-in Bluetooth provides another wireless headset option. Therefore, businesses can select the headset type that best suits each user.

This wide headset support is useful for call centres and busy office staff. As a result, users can work more comfortably during long calls.

GDMS gives IT teams one place to:

• Set up new phones
