Grandstream GXP1625 IP Phone, 2 Lines, Backlit LCD, PoE

Overview

The Grandstream GXP1625 is a two-line desk phone from the GXP16xx basic range with a backlit display, HD audio and shared line support. It suits admin staff, small offices, clinics and branch desks with light to medium call volumes, where an easy-to-learn phone is more useful than a long feature list. It accepts Power over Ethernet (PoE) and also comes with a power adapter.

Is it right for you?

• Suits users with light to medium call volumes: admin staff, small offices, clinics and branch desks.
• Compared with the GXP1610 it adds a backlit display and shared line features while keeping the simple keypad layout.
• Choose it where desks have PoE switch ports; the adapter in the box covers desks without. The GXP1620 is the same phone without PoE.
• If you need to see whether colleagues are busy, the GXP1628 adds 8 busy lamp field (BLF) keys, Gigabit ports and PoE.
• 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.
• Backlit 132 x 48 pixel (2.95 inch) graphical LCD, easier to read in a dim office.
• Dual switched 10/100 Mbps Ethernet ports with integrated Power over Ethernet (PoE, 802.3af Class 2), so one cable serves the phone and the PC beside it.
• HD (high-definition) wideband audio on handset and speakerphone, with 3-way audio conferencing.
• Shared call appearance (SCA) and bridged line appearance (BLA), so a line can be shared between desks, plus call park and pickup.
• Up to 1,000 contacts and 200 call history 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.

Installation

The stand offers two angles, and the phone can be wall mounted. A single cable serves both the phone and a PC through the second switched port. A telephony installer or IT team registers it to the call server, 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.
