Grandstream GRP2615 IP Phone, 10 Lines, 16 SIP, 4.3 Inch Colour, Wi-Fi

Overview

A reception or operator desk that may grow into a full attendant console needs a phone that can take plug-on modules. The Grandstream GRP2615 is a 10-line phone from the GRP2600 Professional range built around a 4.3 inch colour screen: 16 Session Initiation Protocol (SIP) accounts, 40 built-in digital busy lamp field (BLF) keys and support for up to four GBX20 expansion modules. It connects by Gigabit Power over Ethernet (PoE) cable or Wi-Fi, has Bluetooth for headsets and comes with a 12 V adapter.

Is it right for you?

• Suits receptionists, operators and executive assistants who monitor many extensions.
• Suits businesses that want an attendant console that can grow with plug-on modules.
• Audio conferencing is 3-way on this model.
• Choose the GRP2616 instead if you want six lines with a second 2.4 inch side display rather than module support.

Key features

• 10 lines and 16 SIP accounts, so one handset can answer up to 16 numbers and hold 10 calls.
• 4.3 inch colour screen (480 x 272) with 40 built-in digital BLF keys, so you can watch and transfer to many colleagues from the phone itself.
• 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.
• Dual-band 2.4 and 5 GHz Wi-Fi 6 (802.11a/b/g/n/ac/ax) on hardware version 5.0 and above, so the phone can use the less crowded 5 GHz band in a busy office.
• Built-in Bluetooth, so a wireless headset can pair straight to the phone.
• High-definition (HD) wideband audio on the handset and speakerphone, and 3-way audio conferencing with Opus and G.722 codecs.
• Dedicated Transfer and Hold keys and a 2,000-entry phonebook.
• USB port and support for GBX20 expansion modules, so the console can grow with the business.
• Swappable faceplate, so you can add your company logo.
• 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 12 V DC, 1 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 2.4 or 5 GHz Wi-Fi network, or a network cable to the desk.
• Only if you want the phone on a wall, the GRP_WM_L 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.
• Only if you want more keys than the phone itself provides, GBX20 expansion modules: up to four can be chained for 160 extra contacts.

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, fit the GRP_WM_L 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

• Wi-Fi 6 applies to hardware version 5.0 and above; older stock may carry an earlier radio, so confirm the hardware version with us if Wi-Fi 6 matters to you.
• Power draw is 6.3 W at most on the adapter or 7.4 W on PoE, so check the switch’s PoE budget on a large roll-out.
• The GRP_WM_L 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.
