Grandstream GRP2603 IP Phone, 3 Lines, 6 SIP Accounts, Gigabit Ports

Overview

A team lead, a small reception desk or a front office juggles several calls and numbers at once. The Grandstream GRP2603 is the three-line model of the GRP2600 Essential range: it registers up to six Session Initiation Protocol (SIP) accounts, has a larger 2.7 inch backlit screen, a dedicated Hold key and two Gigabit ports, while keeping the simple key layout of the series. It comes with a power adapter and has no Power over Ethernet (PoE).

Is it right for you?

• Suits team leads, small reception desks and front offices that handle several calls or numbers at once.
• Suits desks where a computer connects through the phone and needs a Gigabit link.
• Choose the GRP2603P instead if your switch supplies PoE and you want no power socket at the desk.
• Choose the GRP2604 if you want 10 physical busy lamp field (BLF) keys to watch colleagues’ lines.

Key features

• 3 lines and 6 SIP accounts, so a busy desk can hold several calls and answer several numbers.
• 2.7 inch backlit monochrome screen (132 x 64) with 3 dual-colour line keys and a dedicated Hold key, so a busy desk can park and pick up calls quickly.
• Two switched Gigabit (10/100/1000 Mbps) network ports, so a computer connected through the phone keeps its full Gigabit link.
• High-definition (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.
• 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_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, 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 offers two viewing angles, 39 and 45 degrees.

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
