Grandstream GRP2602G Gigabit PoE IP Phone, 2 Lines, 4 SIP Accounts

Overview

In an office with Gigabit cabling, a phone in the chain between the wall and the PC should not slow the computer down. The Grandstream GRP2602G is the Gigabit version of the GRP2602 two-line desk phone: both ports run at 10/100/1000 Mbps with built-in Power over Ethernet (PoE), so a computer daisy-chained through the phone keeps full speed. It has four Session Initiation Protocol (SIP) accounts, two dual-colour line keys, high-definition (HD) audio and an adapter in the box.

Is it right for you?

• Suits offices with Gigabit cabling where PCs share a single network point with the phone.
• Suits staff who need several numbers on one handset, with four SIP accounts and shared line appearance.
• Works with or without PoE, since an adapter is included.
• Choose the GRP2602LG instead if home workers also need a built-in WireGuard virtual private network (VPN) and GS-FEC.

Key features

• 2 lines and 4 SIP accounts, so one phone can carry a personal number and shared lines.
• 2.41 inch backlit monochrome screen (132 x 48) with 2 dual-colour line keys and 4 softkeys, so you can see at a glance which line is ringing or on hold.
• 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 Class 1, 3.84 W) so the phone can draw power from a PoE switch.
• 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.
• Power from either the 5 V DC, 0.6 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 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 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 holds the phone at a single 45 degree angle.

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.
