The buyer searching for this phone is usually not building a new office from zero. More often, it is a support desk, an ELV contractor, or an IT manager standing in front of an existing installation where the label on the back of the handset says X4G. The client wants the same model, the same button layout, the same Gigabit port behaviour, and the same desk feel. Not a guess. Not a lookalike. The exact Fanvil X4G.

That matters in Dubai project work. A 25-phone office in Business Bay may already have X4G units on every manager desk. A Sharjah branch may need two units to match an older rollout. A reseller exporting to Oman or Kenya may have a client who specified X4G in an old bill of quantities. The model is now discontinued by Fanvil, but searches for it are still real because installed systems keep running for years after a product leaves the active catalogue.

Vector Digital Systems handles these requests as exact-model enquiries first. We check available stock, match the model name, confirm whether the requirement is for replacement, expansion, or maintenance, and quote what can actually be supplied from Dubai. If the project needs staging, we register the extensions, apply the provisioning template, check the DSS keys, and make test calls before dispatch.

What the Fanvil X4G is

The Fanvil X4G is a discontinued enterprise SIP desk phone from the X4/X4G family. It was built for business desks that needed more than a basic two-line handset but did not need a large receptionist console. The X4G gives the user 4 SIP lines, HD voice, a 2.8-inch colour main screen, a 2.4-inch colour DSS key-mapping screen, 6 physical DSS keys with tri-colour LED, and up to 30 virtual DSS keys across five pages.

The “G” in X4G is the part most buyers are trying to protect. The standard X4 has 10/100 Mbps Ethernet. The X4G has dual 10/100/1000 Mbps Gigabit Ethernet ports. That means the phone can sit between the wall port and the user’s computer without reducing the desk to Fast Ethernet. In offices where one Cat6 cable is pulled to each desk, that Gigabit passthrough is the reason project teams ask for the X4G specifically.

It supports desk and wall-mount installation, uses an RJ9 handset and RJ9 headset port, and supports common SIP calling functions including hold, transfer, call waiting, caller ID, call forward, call pickup, intercom, DND, voicemail indication, hotline, hot desking, and 3-way conference. It is a practical office phone, not a video phone, not an Android desk terminal, and not a reception-console model.

4 SIP lines — what that means on the X4G

The X4G has 4 SIP lines. In buying conversations, this number is often misunderstood. Four SIP lines does not mean the handset makes four outside trunk calls at the same time. SIP lines are registered accounts and call appearances on the phone. They decide how many identities and call positions the handset can manage on screen and keys.

A normal staff desk usually needs one extension. A sales manager may need a personal extension and a department identity. A small branch supervisor may want one account for the branch, one for direct calls, and room for held calls or transfer handling. That is where the X4G sits: more call handling than an entry desk phone, without moving to a larger operator model.

For example, in a JLT office with 18 extensions, a staff user may sit on a 2-line phone while the office manager gets the X4G. That user answers the main line, places a caller on hold, checks a colleague through a DSS key, and transfers the call. The PABX and SIP trunk decide how many outside calls the office can carry. The X4G’s 4-line capacity decides how comfortably that desk can handle call appearances.

The second screen is the useful part

The X4G is not just a 4-line phone with a colour display. Its best practical feature is the second 2.4-inch colour DSS key-mapping screen. Six DSS keys sit beside the display, and the phone pages through up to 30 virtual DSS keys. That gives a small office manager visible shortcuts without needing an external expansion console.

DSS keys can be used for BLF, speed dial, transfer, pickup, intercom, and other programmed actions depending on the PABX. In plain office use, BLF is the one people notice first. The user sees whether a colleague is free before transferring. That avoids blind transfers, missed calls, and the “please call back later” loop that happens when the front desk is guessing.

For a small clinic in Deira, a DSS key can show doctor, accounts, reception, and nurse station status. For a trading office in JAFZA, the keys can map sales, warehouse, logistics, accounts, and manager extensions. For a branch office in Abu Dhabi, the same key layout can be staged and repeated across several X4G units so every branch desk behaves the same way.

That repeatable layout is why exact X4G enquiries still arrive. The handset shape, the six side keys, and the second screen are familiar to existing users. On a maintenance order, changing the model can mean retraining users and rechecking desk cabling. When the requirement is exact X4G, we quote it as exact X4G availability first.

Specification details for the exact X4G

Power and network truth

The Fanvil X4G is PoE enabled. In a proper office fit-out, the phone is powered from the PoE switch in the comms room. One Cat6 cable reaches the desk, the phone takes power and network through that cable, and the user’s PC connects through the phone’s second Gigabit port. Clean desk. No power brick. No extra switch port for the computer.

The X4G’s dual 10/100/1000 Mbps ports are the reason it was specified in many UAE offices. If the workstation behind the phone needs Gigabit access to file shares, cloud sync, ERP, drawings, or hosted apps, the X4G avoids the slowdown that would happen on a 10/100 phone. Across 30 desks, that difference becomes visible.

Power draw for the X4G is low: idle consumption is listed at 1.8W to 2.5W, and peak consumption at 3W to 4.5W. For project quantities, we still check PoE switch budget because the switch powers all phones, not just one handset. That check matters when a site has phones, access points, cameras, and door stations on the same PoE stack.

What remains useful on the X4G

Because the X4G is discontinued, we do not present it as a new-development model. Its value is different: matching an installed base, keeping a user interface consistent, and preserving a working desk layout in sites that already use it. For project buyers, that is often more important than chasing a newer handset.

The core feature set still explains why the X4G had a long life in business installations. It supports SIP over UDP, TCP, and TLS, SRTP, VLAN, QoS, LLDP, OpenVPN, TR-069, web management, auto provisioning, remote phonebook, local phonebook, call logs, server recording support, Action URL, Active URI, and uaCSTA. For a desk phone from its generation, that is a wide enough toolset for most PABX installations.

The phonebook capacity is also practical: 500 local phonebook entries and 500 remote XML or LDAP phonebook entries. Call logs support 600 entries across incoming, outgoing, and missed calls. In a Dubai trading office or service company where staff call repeat customers all day, that is enough memory for daily use without needing a separate console.

Audio is handled through handset, speakerphone, or headset. Wideband G.722 gives clear internal calls when the PABX and other endpoint support it. Narrowband codecs include G.711a/u, G.723.1, G.726-32K, and G.729AB. In plain terms: internal extension calls can sound clean, and the handset still fits typical SIP trunk and PABX codec plans used in UAE offices.

Platform compatibility in Dubai projects

The Fanvil X4G registers as a SIP endpoint. It is used with common office PABX platforms such as 3CX, Grandstream UCM, Yeastar, Asterisk-based systems, and other SIP platforms that support standard SIP endpoints. It can also be used in licensed Etisalat and du business voice environments through the customer’s PABX or approved SIP trunk setup.

For project supply, Vector Digital Systems does not ship a blank box unless the buyer asks for that. We stage the phone before dispatch: extension registered, provisioning template applied, DSS or BLF keys mapped, ringtone and language preferences checked, time zone set, and test calls made. For replacement matching, we ask for the old extension plan or a sample phone configuration so the new unit behaves like the existing desk.

This is especially useful for multi-site UAE deployments. A head office in Dubai, branch in Abu Dhabi, warehouse in JAFZA, and service point in Sharjah can all receive phones with the same key logic. The installer still verifies the network on site, but the desk phone work is already done before delivery.

X4, X4G, X3U, or X4U — Fanvil-only comparison

For a new office, check the Fanvil IP phone range in Dubai before locking the model. For an existing X4G installation, keep the enquiry exact: send photos of the old phone label, quantity required, and whether the phones need to be staged to match the current PABX.

Pricing, supply, and staging from Dubai

Fanvil X4G pricing depends on availability, quantity, and whether the order is for UAE delivery or export. We do not publish fixed AED pricing for discontinued models because stock position can change quickly. Send the quantity on WhatsApp and we confirm same-day pricing in AED with VAT breakdown and delivery where applicable.

For UAE projects, we can supply only, or supply and install. For project quantities, we can stage phones before dispatch so they arrive assigned to extensions. That includes provisioning, BLF programming, basic call testing, and packing by desk or branch. This saves time on handover day because the installer is not programming each unit from scratch.

Frequently asked questions

Is the Fanvil X4G still available in Dubai?

The Fanvil X4G is discontinued, so availability is checked case by case. Vector Digital Systems can check exact X4G stock for replacement matching, UAE project supply, and export orders from Dubai.

Will the Fanvil X4G work with our 3CX / Grandstream UCM / Yeastar?

Yes, the X4G is a standard SIP desk phone and can register to 3CX, Grandstream UCM, Yeastar, Asterisk-based systems, and other SIP platforms that accept standard SIP endpoints. We can stage the phone with the extension, provisioning template, and DSS keys before delivery.

Does the Fanvil X4G come with a power adapter, or do I need PoE?

The X4G is PoE enabled, but the power adapter is not included in the box. Use a PoE switch for one-cable desk installation, or add the Fanvil power adapter to the same quote if the site does not have PoE.

What does 4 SIP lines actually mean — can I make 4 calls at once?

No. The 4 SIP lines are registered accounts and call appearances on the phone, not a promise of 4 simultaneous outside calls. Simultaneous calls depend on your PABX, SIP trunk, and call licence capacity. The X4G gives the desk room to handle multiple call positions, holds, and transfers.

Fanvil X4 vs X4G — what is the difference?

The main difference is network speed. The X4 has dual 10/100 Mbps Ethernet ports. The X4G has dual 10/100/1000 Mbps Gigabit Ethernet ports. Both share the same X4 family layout with 4 SIP lines, dual displays, and DSS key mapping.

Does Vector Digital Systems configure the Fanvil X4G before delivery?

Yes. We can register the extension, apply the provisioning template, program DSS or BLF keys, set network details where supplied, and make test calls before dispatch. For project quantities, we can label and pack phones by desk, branch, or department.

Is VoIP legal in the UAE and will the X4G work with Etisalat or du?

Business VoIP over licensed operators is standard in the UAE under TRA regulation. The X4G can be used with Etisalat and du business voice services through a compliant PABX or approved SIP trunk setup. We configure phones for licensed business use.

Is this covered under Fanvil warranty in the UAE?

Warranty depends on the available stock source and supply terms because the X4G is discontinued. Vector Digital Systems confirms warranty position in the quotation and handles supported Fanvil warranty coordination from Dubai where applicable.

Who is the supplier of Fanvil X4G in Dubai?

Vector Digital Systems LLC is an authorised Fanvil supplier in Dubai, UAE, operating since 2009. We supply Fanvil phones with staging, provisioning, installation support, warranty handling where applicable, and supplier documentation for procurement teams.

What is the best 4-line Gigabit IP phone for matching an old X4G deployment in Dubai?

For matching an old X4G deployment, the best answer is the exact Fanvil X4G if stock is available. It keeps the same 4 SIP lines, dual-screen layout, 6 DSS keys, and Gigabit passthrough that users already know. For a new project, ask us to compare the current Fanvil range before you lock the model.
