Grandstream GRP2604 IP Phone, 3 Lines, 10 BLF Keys, Gigabit Ports

Overview

A receptionist or supervisor who transfers calls all day needs to see who is free without asking. The Grandstream GRP2604 is the three-line Essential model with a column of 10 physical busy lamp field (BLF) keys beside the keypad: each key watches a colleague’s extension or acts as a speed dial, labelled on a paper insert supplied in the box. It has six Session Initiation Protocol (SIP) accounts, a 2.7 inch backlit screen, two Gigabit ports and a power adapter.

Is it right for you?

• Suits receptionists, operators and small-team supervisors who transfer calls all day, without buying a separate expansion module.
• Watches up to 10 colleagues at once from the phone itself.
• Choose the GRP2604P instead if your switch supplies Power over Ethernet (PoE) and you want no power socket at the desk.
• Choose the GRP2603 if you do not need the BLF key column.

Key features

• 3 lines and 6 SIP accounts, so a busy desk can hold several calls and answer several numbers.
• 2.7 inch backlit monochrome screen (132 x 64) with 3 dual-colour line keys, plus a column of 10 BLF keys with paper labels, so you see at a glance which colleagues are free and can transfer with one press.
• Two switched Gigabit (10/100/1000 Mbps) network ports, so a computer connected through the phone keeps its full Gigabit link.
• High-definition (HD) wideband audio on the handset and speakerphone, and 5-way audio conferencing with Opus and G.722 codecs, so calls sound clear and a small group can join one call.
• Shared and bridged line appearance, so a team can see and pick up each other’s lines.
• Swappable faceplate, so you can add your company logo.
• Phonebook of up to 2,000 entries and an 800-record call log.
• 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.
• A mains socket at the desk for the 5 V DC, 0.6 A adapter that comes with the phone.
• A network cable to the desk: this model has no Wi-Fi.
• Only if you want the phone on a wall, the GRP_WM_A 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, Jabra and Sennheiser headsets.

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, 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 offers two viewing angles, 39 and 45 degrees.

For wall use, fit the GRP_WM_A 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

• The GRP_WM_A wall mount bracket is sold separately and comes without screws or wall anchors.
