Grandstream GRP2602LP Essential Lite PoE IP Phone, 2 Lines, 4 SIP

Overview

An office on Power over Ethernet (PoE) switches and its remote employees can share one phone model. The Grandstream GRP2602LP is a two-line desk phone from the GRP2600 Essential Lite range with four Session Initiation Protocol (SIP) accounts, two dual-colour line keys and high-definition (HD) audio, powered through its network port, plus a built-in WireGuard virtual private network (VPN) client and GS-FEC packet-loss protection for staff working from home. No adapter is supplied.

Is it right for you?

• Suits offices and service-provider deployments on PoE switches that want one cable per desk.
• Suits remote employees who need an encrypted connection to the office phone system without extra hardware, and have a PoE injector or switch at home.
• Choose the GRP2602LG instead if you want Gigabit ports and a power adapter in the box.
• Choose the GRP2602P if you do not need the VPN and GS-FEC additions.

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.
• One 10/100 Mbps network port and one 10/100 Mbps PC port, so a computer can share the desk’s network cable through the phone, 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.
• An IEEE 802.3af PoE switch port or PoE injector. No power adapter is supplied, so if your switch has no PoE, order a 5 V DC, 0.6 A adapter separately.
• 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 a PoE switch port or injector, 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

• No power adapter is supplied. Plan on an IEEE 802.3af PoE switch port or injector, or order a 5 V DC, 0.6 A adapter separately.
• 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.
