Grandstream GRP2602LG Essential Lite Gigabit IP Phone, 2 Lines, 4 SIP

Overview

When a PC and a phone share one network point, a 10/100 phone caps the computer at 100 Mbps. The Grandstream GRP2602LG is the Gigabit model of the GRP2600 Essential Lite range: both ports run at 10/100/1000 Mbps, the network port takes Power over Ethernet (PoE), and the phone keeps the range’s built-in WireGuard virtual private network (VPN) and GS-FEC packet-loss protection. It has two lines, four Session Initiation Protocol (SIP) accounts, high-definition (HD) audio and an adapter in the box.

Is it right for you?

• Suits offices where each desk has a single network point shared by a PC and a phone, and IT does not want the phone to slow the computer.
• Suits home workers who need an encrypted link to the office phone system without a VPN router.
• Works with or without PoE, since an adapter is included.
• Choose the GRP2602LP instead if 10/100 ports are enough and every desk has PoE.

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.
• Built-in WireGuard VPN client, so a home worker’s phone reaches the office phone system over an encrypted tunnel without a separate VPN router.
• GS-FEC forward error correction, designed to keep speech intelligible through up to 70% packet loss on a poor broadband link.
• Multicast paging, shared line appearance and a 500-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 SRTP call encryption.

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, and works with BroadSoft, Metaswitch, Kandy, 3CX, Zoom, NetSapiens, RingCentral, Asterisk, FreeSWITCH and OpenSIPS platforms.
• 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. The GS EXT smartphone app can act as a virtual expansion module, adding programmable keys on a phone screen.

Before you buy

• The GRP_WM_A 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.
