Grandstream GRP2636 IP Phone, 12 Lines, 24 Paper Label Keys, Wi-Fi 6

Overview

A reception or attendant position that needs many fixed keys in view at once, without adding an expansion module, is what the Grandstream GRP2636 is built for. It is a 12-line phone with 16 Session Initiation Protocol (SIP) accounts, a 4.3 inch colour screen and a column of 24 physical multi-purpose keys with a paper label slot. It keeps the Wi-Fi, Bluetooth, USB headset and Gigabit Power over Ethernet (PoE) features of the GRP262x and GRP263x models, and comes with a 12 V adapter.

Is it right for you?

• Suits reception and attendant positions that need 24 fixed busy lamp field (BLF) or speed-dial keys in view at once.
• Suits headset users, with Bluetooth, USB and RJ9 options on the same phone.
• Works on Wi-Fi or cable, powered by PoE or the included adapter.
• Choose the GRP2634 instead if 10 fixed keys and eight lines are enough.

Key features

• 12 lines and 16 SIP accounts, so one handset can answer up to 16 numbers and hold 12 calls.
• 4.3 inch colour screen (480 x 272) with 12 line keys, plus a column of 24 multi-purpose keys with a paper label slot, so a whole team is always one press away.
• 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 with dual microphones on the handset and speakerphone, and 5-way audio conferencing with Opus and G.722 codecs.
• 2,000-entry phonebook and a 2,000-record call log.
• 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, 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, and the USB port takes Grandstream GUV series and other USB 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

• 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.
• It does not support the GBX20 expansion module; its 24 fixed keys take that role.
• Power draw is 3.2 W at most on the adapter or 4.3 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.
