Grandstream GXP2140 Enterprise IP Phone | 4 Lines, 4.3" Color LCD, PoE & Expansion

Grandstream GXP2140 – Enterprise IP Phone with 4.3″ Colour Display, Bluetooth & Expansion

The Grandstream GXP2140 is a sleek, feature‑loaded Enterprise IP phone that combines high‑definition audio, extensive programmability and a rich visual interface. It is built for professionals who handle medium‑to‑high call volumes and need instant access to colleagues, extensions and advanced telephony functions.

Superior Audio & Conferencing

The GXP2140 delivers HD wideband audio on both the handset and the full‑duplex speakerphone, supporting G.722, iLBC and other leading codecs for natural, crystal‑clear conversations. Built‑in 5‑way audio conferencing lets you initiate multi‑party discussions directly from the desktop – no external bridge required.

High‑Speed Networking & Simplified Cabling

Equipped with dual auto‑sensing 10/100/1000 Mbps Gigabit Ethernet ports, the GXP2140 ensures the fastest possible wire‑speed connection for both the phone and a connected PC. The **integrated PoE (802.3af) ** allows a single Ethernet cable to carry both power and data (DC adapter also supplied), keeping the desk clean and free of extra power adapters.

Bluetooth, USB & EHS for Headset Freedom

On‑board Bluetooth lets you pair the phone with a wireless headset, or with your mobile device to transfer contact books and ongoing calls seamlessly. A built‑in USB port adds further peripheral support, and Electronic Hook Switch (EHS) support for Plantronics (Poly) headsets enables remote answer/end control directly from the headset.

Expand Your Call Control with GXP2200EXT Modules

A unique strength of the GXP2140 is its support for GXP2200EXT extension modules. Each module adds a 128×384 backlit graphic LCD with 20 programmable dual‑color buttons and two page keys, delivering 40 contacts per module. You can daisy‑chain up to four modules, bringing the total to an impressive 160 programmable BLF / speed‑dial keys.

These keys can be configured for:

• BLF (Busy Lamp Field) – monitor the real‑time status of extensions (idle, ringing, busy)

• Speed‑dial – one‑touch calling to frequently used numbers

• Call park / pick‑up

• Presence – see whether a colleague is available

• Intercom

• Conference / transfer / forward

This makes the GXP2140 a powerful attendant console when paired with the optional modules, ideal for busy reception desks and large open‑plan offices.

Enterprise‑Grade Security & Zero‑Touch Deployment

Security is paramount in modern business communications. The GXP2140 supports SRTP and TLS encryption to protect signalling and voice media, along with HTTPS, SSH and 802.1X authentication.

Administrators will appreciate the automated provisioning options:

• Zero‑configuration with Grandstream UCM series IP PBXs

• TR‑069 for remote management

• AES‑encrypted XML configuration files for secure mass deployment

• Full GDMS (Grandstream Device Management System) support for cloud‑based monitoring and provisioning

Pre‑Loaded Apps & Customisation

The GXP2140 arrives with pre‑loaded weather and currency exchange widgets as well as custom XML applications, and the user‑friendly web interface makes it easy to configure every aspect of the phone.
