Grandstream 10 line Carrier-Grade IP Phone GRP2615

The Grandstream GRP2615 10-Line Carrier-Grade IP Phone is built for businesses that need a powerful and easy-to-manage desk phone. It combines advanced call features, clear HD sound, wireless connectivity, and strong security in one professional device.

The phone supports 10 line keys and up to 16 SIP accounts. As a result, users can manage several extensions, departments, or business lines from one phone. This makes it suitable for staff who handle a high number of calls throughout the day.

In addition, the GRP2615 features a large 4.3-inch colour LCD screen. The display provides a clear view of contacts, call history, voicemail, line status, and phone settings. Therefore, users can access important features quickly without moving through long menus.

The GRP2615 is part of Grandstream’s professional carrier-grade phone range. Consequently, it supports zero-touch setup and centralized cloud management. This makes it easier for IT teams to install and manage many phones across one or several business locations.

Supports 10 Lines and 16 SIP Accounts

The Grandstream GRP2615 supports 10 line keys and up to 16 SIP accounts. Therefore, users can connect several extensions or VoIP accounts to one device.

This feature is useful for reception desks, customer care teams, sales departments, and managers. For example, a receptionist can handle calls for different departments from one phone. At the same time, the line keys provide quick access to active calls and available extensions.

In addition, the phone supports several common call tools. These include call hold, call transfer, call forwarding, call waiting, speed dial, call park, and Do Not Disturb.

As a result, employees can handle daily calls more quickly and provide better service to customers.

Large 4.3-Inch Colour Display

The GRP2615 includes a bright 4.3-inch colour LCD screen with a clear and easy-to-use layout.

Users can view:

• Caller information
• Contact lists
• Call history
• Voicemail alerts
• Line status
• Phone menus
• Network settings
• Programmable key functions

Because the screen is large, users can read call details without difficulty. Furthermore, the simple menu design reduces training time for new employees.

The phone also has a replaceable faceplate. Therefore, businesses can add their company name or logo for a more branded desk setup.

40 Built-In Digital BLF Keys

The Grandstream GRP2615 includes 40 built-in digital multi-purpose keys. These keys can work as BLF keys, speed-dial keys, call pickup keys, or other programmable shortcuts.

BLF keys allow users to see whether another extension is free, busy, or ringing. As a result, receptionists and team leaders can transfer calls more accurately.

The keys can also help users reach common contacts with one touch. Therefore, employees spend less time searching through contact lists or entering extension numbers.

For users who need even more keys, the GRP2615 supports an optional extension module. Each supported module adds extra BLF and speed-dial keys. Consequently, the phone can meet the needs of busy reception areas and large office teams.

Built-In Dual-Band Wi-Fi

The Grandstream GRP2615 includes built-in dual-band Wi-Fi that supports both 2.4GHz and 5GHz networks.

This wireless feature allows the phone to connect to a business network without a direct Ethernet cable. Therefore, it provides more freedom when choosing where to place the phone.

Wi-Fi is especially useful in offices where network cables are not available at every desk. It can also help reduce new cabling costs during office changes or expansion.

In addition, dual-band support helps the phone connect to either a 2.4GHz or 5GHz wireless network. As a result, businesses can choose the best available connection for their setup.

Integrated Bluetooth Support

The GRP2615 also features built-in Bluetooth.

Users can connect compatible Bluetooth headsets for hands-free calling. Therefore, employees can move around their work area while remaining connected to a call.

Bluetooth headsets are useful for receptionists, customer support agents, managers, and sales teams. In addition, they help reduce the need to hold the handset during long calls.

As a result, users can work more comfortably while handling documents, using a computer, or checking customer records.

Clear HD Audio

The Grandstream GRP2615 provides HD audio through both the handset and speakerphone.

It supports wideband audio codecs, which help produce clear and natural voice sound. Therefore, callers can hear each other more easily during business conversations.

The full-duplex speakerphone also allows both sides to speak at the same time. As a result, group discussions sound more natural and less interrupted.

Clear sound is especially important in customer service, sales, hotels, healthcare, and other workplaces where call quality affects service delivery.

Dual Gigabit Ethernet Ports

The phone includes two auto-sensing Gigabit Ethernet ports.

One port connects the phone to the network. Meanwhile, the second port can connect a nearby computer to the same network point.

This setup reduces the need for a separate network cable for the computer. Therefore, businesses can use their existing network points more efficiently.

Gigabit Ethernet also supports fast data transfer. As a result, the connected computer can continue to access the network at high speed.

Power over Ethernet Support

The Grandstream GRP2615 supports Power over Ethernet, also known as PoE.

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

This makes installation faster and reduces cable clutter around the desk. In addition, centralized PoE power can make it easier to protect phones using a UPS connected to the network switch.

As a result, the business phone system may continue running during short power interruptions, depending on the UPS setup.

Easy Setup and Central Management

The GRP2615 supports the Grandstream Device Management System, also called GDMS.

GDMS allows IT teams to manage phones from one cloud platform. For example, administrators can:

• Add new phones
• Change phone settings
• Update firmware
• Check device status
• Apply configuration files
• Troubleshoot remote devices
• Manage phones across several offices

Therefore, businesses can save time when deploying or supporting many phones.

The phone also supports zero-touch provisioning. As a result, a new device can download its settings automatically after it connects to the network.

Enterprise-Grade Security

Business calls and phone data need strong protection. For this reason, Grandstream includes several security features in the GRP2615.

These features include:

• Secure boot
• Dual firmware images
• Encrypted data storage
• TLS support

• Network authentication

Together, these features help protect the phone from unwanted access. In addition, encrypted voice traffic helps improve privacy during business calls.
