Grandstream GRP2612G Gigabit PoE IP Phone, 4 Lines, Colour Screen

Overview

In a Gigabit-cabled office, one network point per desk is often shared between the phone and a PC. The Grandstream GRP2612G is the Gigabit model of the GRP2612 four-line phone: both ports run at 10/100/1000 Mbps with built-in Power over Ethernet (PoE), so a computer connected through the phone keeps full speed. It has four Session Initiation Protocol (SIP) accounts, a 2.4 inch colour screen with up to 16 virtual busy lamp field (BLF) keys, a dedicated Hold key and high-definition (HD) audio, with an adapter in the box.

Is it right for you?

• Suits Gigabit-cabled offices where the phone and a PC share one network point.
• Works with or without PoE, since an adapter is included.
• Choose the GRP2612W instead if some desks must connect over Wi-Fi.

Key features

• 4 lines and 4 SIP accounts, so one desk can answer four numbers or hold four calls.
• 2.4 inch colour screen (320 x 240) whose 4 line keys page through up to 16 virtual BLF keys, with a dedicated Hold key, so you can watch colleagues’ lines and park calls quickly.
• 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) 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.
• Swappable faceplate, so you can add your company logo.
• XML screen customisation, a 1,000-entry phonebook and a 1,000-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, a wall mount bracket, sold separately. Ask us to confirm the bracket for this model before ordering one.
• Only if you want a wired headset, one with an RJ9 plug; electronic hook switch (EHS) control works with Plantronics 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 gives two desk angles.

For wall use, a bracket is needed; ask us to confirm the right one for this model before ordering it.

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

• Power draw is 3 W at most on the adapter or 3.8 W on PoE.
• Wall mounting needs a bracket sold separately, and no bracket is named for this exact model, so confirm it with us before ordering.
• It does not take an expansion module.
• It is made for indoor desks, with an operating range of 0 to 40 °C.
