Grandstream GRP2612 Colour Screen IP Phone, 4 Lines, 4 SIP Accounts

Overview

A small sales desk, clinic front office or department secretary answers several numbers and shares lines with a team. The Grandstream GRP2612 is the four-line model of the GRP2600 Professional range: 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. It connects over 10/100 Mbps Ethernet and comes with a power adapter; there is no Power over Ethernet (PoE) or Wi-Fi.

Is it right for you?

• Suits staff who answer several numbers or share lines with a team, on standard 10/100 office networks.
• Choose the GRP2612P instead if your switch supplies PoE, the GRP2612W for Wi-Fi, or the GRP2612G if the desk PC needs a Gigabit link through the phone.

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 10/100 Mbps network ports, so a computer can share the desk’s network cable through the phone.
• 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.
• 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_S 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 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 gives two desk angles.

For wall use, fit the GRP_WM_S 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.
