Grandstream Gateways & ATA Dubai — Old Devices, New System. No Funeral.
The fax machine nobody will let you throw away. Three hundred analog phones bolted to hotel walls. Neither needs replacing — they need a bridge.
A Grandstream gateway connects anything analog — desk phones, fax machines, PSTN lines, door intercoms, PA systems — to a modern IP phone system, with every extension, feature and dial tone intact. From a single-port HT801 to the 48-port GXW4248 and the GXW4501 PRI, configured for your Etisalat or du lines before it ships.
Vector Digital Systems is an authorized Grandstream distributor in Dubai, bridging analog estates into IP systems since 2009.
- HT series ATAs — 1 to 8 ports, from stock
- GXW FXS gateways — 16 to 48 analog devices
- GXW FXO gateways — your analog lines on a new system
- GXW4501 PRI — E1/T1 trunks for large deployments
- T.38 fax & carrier configuration, tested on your line
What a Gateway Actually Does — Three Bridges, Three Jobs
A Grandstream gateway converts analog signals into SIP — the language every modern phone system speaks — so the analog equipment you already own keeps working on a modern IP system. Three kinds of bridge exist, and the whole decision is knowing which one your building needs.
FXS — for devices. Your analog phones, fax machines and intercoms plug into the gateway; the gateway puts them on the network. The handset you already own becomes an IP extension without knowing it changed jobs.
FXO — for lines. Your existing Etisalat or du analog lines plug into the gateway; the new IP PBX keeps answering and dialing on them exactly as before. The system changes underneath; the callers notice nothing.
PRI — for trunks. E1/T1 digital lines — the 30-channel services large offices, call centers and hotels run on — connect through one box, full carrier compatibility, nothing preserved except everything that matters.
Keep the Handsets You Own. Spend the Money Where It Shows.
Most NEC and Panasonic replacements go wrong at the same line item: the phones. Three hundred proprietary handsets that only worked on the old system — quoted for replacement because nobody mentioned the gateway. The analog and basic handsets in that pile — and there are always some — don't need replacing at all. They need an FXS port.
Through Grandstream FXS gateways, analog phones from the dead system join the new IP platform with extensions, features and dial tone intact. For a hotel, that is the price of three hundred new room phones saved. For an office, it is the difference between a calm migration and a weekend of rewiring. The detailed paths live on our NEC end-of-life page and Panasonic end-of-life page, and the platform it all lands on is the Grandstream UCM6300 PBX.
HT Series ATAs — One Device to Eight, Per Box
The HT series is the small end of the bridge family: compact adapters that put one to eight analog devices on the network, each with T.38 fax support, SIP accounts and GDMS management built in. Every model from Dubai stock, configured before it ships.
| Model | Ports | What it connects | Best for |
|---|---|---|---|
| HT701 | 1 FXS | One analog device | The single fax or the one phone that must stay |
| HT801 | 1 FXS | One analog device | Same job, current model — our default single-port |
| HT802 | 2 FXS | Two devices side by side | The desk with a phone and a fax |
| HT812 | 2 FXS + router | Devices plus network pass-through | Desks with one network point |
| HT813 | 8 FXS | Eight analog devices | Small offices keeping their analog fleet |
| HT814 | 4 FXS + router | Four devices + routing | Branch desks and counters |
| HT818 | 8 FXS + router | Eight devices + routing | The analog corner of a growing office |
| HT841 / HT881 | FXS + FXO hybrid | Devices and lines together | Keeping phones and lines at once |
Pricing: Gateways are quoted per model and volume — single units, mixed consignments, or project quantities. Send your device map on WhatsApp and the itemised quote comes back the same working day.
When the Analog Estate Has Hundreds of Endpoints
A hotel with 300 room phones. A hospital with analog lines on every ward. An enterprise tower where the intercoms, faxes and desk phones never made it to IP. The GXW series is the bridge built for that scale — up to 48 ports per unit, all managed from one GDMS dashboard.
GXW4104 / GXW4108 — the line keepers (FXO)
- Connect 4 or 8 analog Etisalat or du lines to your IP PBX
- Your existing numbers and lines keep serving the new system
- Failover and T.38 fax built in
GXW4216–4248 — the phone keepers (FXS)
- 16, 24, 32 or 48 analog phones per unit join the network
- New V2 hardware on current models (GXW4232 V2, GXW4248 V2)
- Stacked per floor, per ward, per building — one dashboard
PRI Lines to IP — Thirty Channels Through One Box
Large buildings don't run on ordinary phone lines — they run on E1/T1 PRI trunks, thirty channels of carrier-grade service. The GXW4501 connects that trunk to your IP system with full carrier compatibility: the building's line capacity stays exactly as it is, while the system behind it goes fully modern. For call centers, hotels and enterprise towers, it is the cleanest path from a PRI estate to an IP platform — no channel loss, no renumbering, no drama.
Yes, Fax Still Matters Here. We Design It In.
Banks move documents by fax. Government departments ask for faxes. Shipping companies confirm loads by fax. In this market, "just stop using fax" is not a strategy — it's a fantasy that costs you the account. Fax over IP runs on the T.38 protocol, which every Grandstream gateway we supply supports end to end — and we configure and test it against your specific Etisalat or du line before the box ships, because in this region the carrier layer is not neutral and T.38 done generically is T.38 done badly.
The Box Every Reseller Ships First — Compact, High-Demand, Easy Margin
Gateways are the smartest item in an export consignment: small, light, universally needed, and the first thing an installer in Nairobi or Tashkent runs out of. We supply resellers and integrators across 52 markets with trade pricing, mixed consignments (gateways consolidated with PBX systems, phones and switches in one export file), and package weights and dimensions included in every quotation — because we know your shipping cost decides your margin before you ever sell the box.
Grandstream Gateways & ATA in Dubai — the Questions We Get Every Week
What is an ATA (analog telephone adapter)?
An ATA is a small device that lets ordinary analog equipment — desk phones, fax machines, cordless bases, door intercoms — work on a modern IP phone system. It converts the analog signal into SIP, the language every modern PBX speaks. In Dubai, a Grandstream ATA starts from a single port (HT701/HT801) for one device and scales to 48 ports (GXW4248) for entire floors of analog phones.
What is the difference between FXS and FXO ports?
FXS connects analog devices to the IP system — your analog phones, fax machines and intercoms plug into the gateway, and the gateway puts them on the network. FXO does the reverse: it connects analog phone lines to the IP system — your existing Etisalat or du analog lines plug into the gateway, and the new IP PBX keeps using them. Most migrations need one, the other, or both — which is why we map your devices and lines before quoting anything.
What is a PRI gateway, and when do I need one?
A PRI gateway (the Grandstream GXW4501) connects an E1/T1 digital trunk — the high-capacity line used by large offices, call centers and hotels — to an IP phone system. You need one when your building runs on an E1/PRI line rather than ordinary analog or SIP trunks, or when a large analog infrastructure must be preserved while the system behind it goes IP. It replaces nothing and preserves everything: one box, thirty channels, full carrier compatibility.
Can I keep my analog phones when I move to an IP phone system?
Yes — that is exactly what FXS gateways exist for. Your analog phones plug into the gateway, the gateway joins the new IP PBX over the network, and every old handset keeps working with its extension, features and dial tone intact. For a hotel or a large office, this cuts the migration cost by the price of hundreds of new phones — the single biggest saving in most legacy replacements we run.
Will my fax machine work over a VoIP system?
Yes — with the right gateway and configuration. Fax over IP runs on the T.38 protocol, which Grandstream gateways support end to end, and we configure it for the UAE's lines before delivery. Fax remains genuinely necessary here — banks, government departments and shipping companies still move documents by fax daily — so we design it in rather than hoping it works.
How many analog phones can one gateway support?
From one to 48 per unit, and units stack. The HT801 carries a single analog device; the HT813 carries eight; the GXW4216, 4224, 4232 and 4248 carry 16, 24, 32 and 48 respectively. A 300-room hotel might use eight GXW4248s across floors, all managed from one GDMS dashboard. We size the count from your actual phone map, not from the brochure.
What is the difference between Grandstream HT801 and HT802?
One port versus two. The HT801 connects a single analog device — one phone, one fax, one cordless base. The HT802 connects two devices side by side, each with its own extension or line. Everything else — SIP support, T.38 fax, PoE options, GDMS management — is shared between them. For most single-device needs the 801 is the whole answer; for a desk with a phone and a fax, the 802 covers both.
GXW4104 or GXW4216 — which gateway do I need?
Different jobs entirely. The GXW4104 is an FXO gateway — it connects 4 analog lines to your IP PBX (your existing Etisalat or du lines keep serving a new system). The GXW4216 is an FXS gateway — it connects 16 analog phones or devices to the network. If you are preserving lines, think FXO; if you are preserving phones, think FXS; many sites need one of each, and we design both into the same migration.
Do Grandstream gateways work with non-Grandstream phone systems?
Yes — Grandstream gateways are standard SIP devices and register on 3CX, Yeastar, Avaya, Asterisk and hosted platforms, not just Grandstream UCM systems. The T.38 fax support and provisioning work the same way. If you change platforms later, the gateways move with you — only the configuration changes.

Do you export Grandstream gateways and ATAs from Dubai?
Yes — we export the full HT and GXW range from Dubai to Qatar, Oman, Iraq, Jordan, Lebanon, Yemen, Syria, Turkey, Saudi Arabia, Uganda, Kenya, Nigeria, Cameroon, Egypt, Ethiopia, Ghana, Mauritania, Mauritius, Morocco, Mozambique, Rwanda, Senegal, South Africa, South Sudan, Sudan, Tanzania, Tunisia, Zambia, Zimbabwe, Algeria, Burkina Faso, Côte d'Ivoire, Malawi, Burundi, Djibouti, Togo, Benin, Gabon, Chad, Seychelles, Angola, Turkmenistan, Uzbekistan, Armenia, Georgia, Bangladesh, Pakistan, Afghanistan, Azerbaijan, Kazakhstan, Kyrgyzstan, and Tajikistan. Gateways are the region's favourite consignment item: compact, high-demand, and easy to ship in volume. Package weights and dimensions are included in every export quotation, and trade pricing applies for resellers and integrators buying in volume.
Can a gateway connect my old analog lines to a new IP PBX?
Yes — that is the FXO gateway's entire job. Your existing Etisalat or du analog lines plug into the GXW4104 or GXW4108, and the new IP system answers and dials on them exactly as before — callers notice nothing while you migrate to SIP at your own pace. When the SIP trunks are ready, the gateway either retires or moves to backup duty.
Do Grandstream gateways work with Etisalat and du lines?
Yes — we configure them for both carriers' analog and ISDN services routinely. FXO gateways take the carriers' analog lines directly; PRI gateways take E1 trunks; and the whole setup is tested on the live line before handover. In this region the carrier layer is not neutral, so the configuration is engineered for your specific line, not copied from a generic template.
Can hotels keep their analog room phones with a gateway?
Yes — it is the cheapest hotel migration we run. The analog room phones stay bolted to the walls; GXW FXS gateways on each floor give the new IP system analog ports; the rooms join the modern platform with PMS integration, wake-up calls and checkout privacy wipe — without rewiring a single room or buying three hundred new handsets. The full hospitality approach is on our hotel phone systems page.
Do you configure gateways before delivery?
Yes — every gateway leaves configured: your SIP accounts, extensions, fax settings and carrier parameters loaded for your specific lines. In this region the carrier layer is not neutral, so we test against your actual Etisalat or du service before the box ships. On your network it is close to plug-and-play — and when it is not, we are one WhatsApp message away.
