Grandstream GXP1628 Gigabit IP Phone, 2 Lines, 8 BLF Keys, PoE

Overview

The Grandstream GXP1628 is a two-line desk phone with eight busy lamp field (BLF) keys that light up to show whether colleagues are on a call, so a receptionist or team lead can transfer calls without guessing. It has Gigabit network ports, so the PC beside it keeps a full-speed connection, and it is powered over the network cable (Power over Ethernet, PoE) or by the adapter in the box. It suits small reception desks, team leads and sales desks.

Is it right for you?

• Suits users who need to see whether colleagues are busy and transfer calls quickly: small reception desks, team leads and sales desks.
• Choose it over the GXP1625 when you need BLF keys or a Gigabit pass-through for the PC. The GXP1625 is the lower-cost 10/100 model without BLF keys.
• If you need a third line and 4-way conferencing, the GXP1630 has the same 8 BLF keys with a larger display.
• BLF keys only work when the call server publishes extension status, which Grandstream UCM systems do.
• It needs a SIP phone system (IP PBX) or hosted VoIP service to register to.

Key features

• 2 Session Initiation Protocol (SIP) accounts, 2 line keys and 3 XML programmable soft keys.
• 8 dual-colour BLF and speed-dial keys beside the backlit 132 x 48 pixel (2.95 inch) display.
• Dual switched Gigabit Ethernet ports (10/100/1000 Mbps) with integrated PoE (802.3af Class 2).
• HD (high-definition) wideband audio on handset and speakerphone, with 3-way audio conferencing.
• Shared call appearance (SCA) and bridged line appearance (BLA), up to 1,000 contacts and 200 call records.
• RJ9 headset jack with electronic hook switch (EHS) support for Plantronics headsets.
• Codecs G.711µ/a, G.722, G.723, G.726-32, G.729A/B and iLBC.

What else you need

• A Session Initiation Protocol (SIP) call server to register to: a Grandstream UCM (Unified Communications Manager) IP PBX, which can also set the phone up with zero configuration, or a hosted internet calling (VoIP) service.
• A network cable to the desk.
• Power from an 802.3af PoE switch port or injector, or from the universal power adapter in the box (100 to 240 V AC input, 5 V DC 600 mA output) and a mains socket.
• For the BLF keys to show status: a call server that publishes extension status, such as a Grandstream UCM.

Installation

The stand offers two angles, and the phone can be wall mounted. Connect the PC to the second Gigabit port so one cable serves both. A telephony installer or IT team registers it to the call server and assigns the BLF keys to the extensions to watch, or a Grandstream UCM can provision it automatically.

Software and licences

Works with standard SIP platforms and Grandstream UCM IP PBXs. Provisioning options include TR-069, AES-encrypted XML files and the Grandstream Device Management System (GDMS), so a batch of phones can be configured without touching each one.

Before you buy

• BLF status depends on the call server supporting it.
