Do We Lose What Works? — No. It Joins.
Every gateway conversation starts the same way. A business is moving to a modern phone system — and somewhere in the building there is analog life that matters: a floor of desk phones that work perfectly, a fax machine the trade licence renewals still travel through, an elevator emergency line, alarm panels, the Etisalat numbers printed on ten years of stationery. The fear is that modernising means abandoning. It does not. A gateway is the piece of equipment whose entire purpose is continuity: the analog world plugs into one side, the IP system lives on the other, and everything keeps working — now as part of one system instead of two.
This page explains the whole subject the way we explain it in meetings: what a gateway actually does, which of your things go where, the fax truth printed in full, what survives a blackout, and what each box costs in AED.
What a Gateway Actually Does — Two Directions, One Box
Strip away the acronyms and a gateway does exactly two things. Direction one — your devices join the system. An analog phone, a fax machine, an elevator handset plugs into an FXS port on the gateway; the gateway registers it to the phone system; from that moment it is an extension — it rings on transfers, dials three digits to any desk, appears in the directory. Direction two — your lines join the system. Your existing Etisalat or du analog line plugs into an FXO port; the system can now answer and dial on the number you have always had. Devices to FXS. Lines to FXO. Every gateway project on earth is some mixture of those two sentences.
Which Gateway Do You Need? — The Families Compared
Five families, one honest table. Find the row that matches what you are holding — a device, a line, a circuit or a SIM — and the rest of this page explains your row in depth.
| Family | What Plugs In | What It Does | Ports | Fax (T.38) | Calls in a Blackout | From (AED) |
|---|---|---|---|---|---|---|
| FXS TA200–TA3200 | Analog phones, fax machines, elevator & alarm lines, door phones, legacy PBX | Devices become extensions of the new system | 2 / 4 / 8 / 16 / 24 / 32 — then stack units | ✓ Yes — fax machines belong here | Devices follow the system's power design | ~AED 910 (8-port TA800) |
| FXO TA410 / TA810 / TA1610 | Your existing Etisalat & du analog lines | Your published numbers join the new system | 4 / 8 / 16 | ✗ No — never wire fax behind FXO | ✓ Yes — exchange-powered line keeps calling | ~AED 1,200 (8-port TA810) · ~AED 2,770 (16-port TA1610) |
| PRI / E1 TE100 / TE200 | E1 / T1 / J1 digital circuits on contract | Bridges the trunk — migrate on your schedule | 1 or 2 circuits · 30 / 60 concurrent calls | ✓ Yes | Follows the circuit and your fallback design | ~AED 3,290 (TE100) · ~AED 3,990 (TE200) |
| BRI TB200 / TB400 | ISDN BRI lines where they still serve | Carries BRI onto the system until retirement day | 2 / 4 | ✓ Yes | Follows the circuit | On request — often better answered by SIP |
| GSM / LTE | Mobile-network SIM cards | Calls over the mobile network — failover and sites fixed lines cannot reach | Varies by model | — | ✓ Independent of fixed lines by nature | Covered on its own dedicated page — ask on WhatsApp |

Your Analog Devices Become Extensions
The Yeastar TA FXS family exists so that working equipment keeps working. Connect analog phones through a TA gateway and they behave as full extensions of the P-Series — receiving transfers from the receptionist, joining ring groups, dialling any desk internally. Fax machines connect the same way and send over T.38, the standard built for fax on IP networks. Even an old analog PBX can be trunked in during a staged migration, so a building modernises floor by floor instead of overnight. The economics are honest: a hundred working analog phones represent money already well spent — the gateway lets you invest in the system, not in replacing handsets that were never the problem. The full range sits in our analog gateway shelf, and the ladder below names the sizes.
The Analog Survivors of 2026 — Each One Has a Port Waiting
The elevator emergency line. Every lift has one; every modernisation must respect it. It can ride an FXS port onto the system — migrated deliberately, tested with your lift maintainer, never assumed. The alarm and fire-panel line. Dialler circuits that must stay alive; we survey them by name and design their path before anything else moves. The fax machine. Trade, medical and legal Dubai still faxes — and it works on IP when it is wired correctly, which the next section explains. The door phone and gate intercom. An FXS port turns them into extensions that ring the right desk. The hotel floor. Hundreds of analog room phones join the system per-floor through stacked FXS gateways — the pattern behind our hotel PBX deployments. The warehouse paging line. Overhead announcement kit joins the same way. None of these is a reason to delay modernising; each is simply a line on our survey sheet with a port waiting for it.
Why Fax Fails on VoIP — and the Wiring Rule That Fixes It Forever
A fax is not a voice, and that single fact explains a decade of broken fax stories. Voice codecs compress sound in ways human ears forgive and fax tones do not — send a fax like a phone call and it arrives as noise. The cure is T.38, the standard that carries fax as fax across the network. Now the rule that saves projects, printed plainly because it deserves printing: in the Yeastar range, T.38 rides the FXS gateways, the TE PRI gateways and the TB BRI gateways — the TA FXO series does not carry it. The architecture follows in one sentence: fax machines belong on FXS ports, always. Wire it that way on day one and faxing simply works, forever. It is a thirty-second decision at design time and a month of misery if it is guessed wrong — which is exactly why the design comes from us, in writing, with the quote.
Your Etisalat & du Lines Join — and the Calls Survive a Blackout
The TA FXO gateways bring the lines you already rent onto the new system: your published numbers keep ringing, the system answers and dials on them, and nothing changes for the callers who have known your number for a decade. Then the part that decides purchases quietly: with PSTN lines on FXO, calling can continue through the analog line even when internet connectivity is down — and the copper line itself draws power from the exchange, not from your building. When the router dies or the street loses power, the business that designed its FXO fallback is still answering. For clinics, security desks and logistics floors, that one paragraph is the whole reason this equipment exists — and we design the fallback deliberately, test it during commissioning, and write it into the handover.
Still on PRI or BRI? Bridge It — Migrate on Your Schedule, Not the Operator's
Businesses with an E1/PRI circuit on contract face a false choice: break the contract or delay the new system. The Yeastar TE gateways dissolve it. The TE100 carries one circuit and the TE200 two — each port software-selectable between E1, T1 and J1 — bridging up to 60 concurrent calls between your digital trunk and the IP system. The PRI keeps working exactly as contracted; the system goes modern today; and when the circuit's retirement day arrives, you move to SIP trunks by configuration, not by forklift. Operators worldwide are switching off digital landline services on their own timetables — the gateway means the timetable that matters is yours. Where ISDN BRI still serves, the TB200 and TB400 carry two and four BRI ports on the same principle — and we will tell you honestly when the better answer is simply moving the number to SIP.
Module or Gateway — Answered Honestly Before You Spend
Here is a fact we state even though it costs us small sales: sometimes you do not need a gateway at all. Yeastar P-Series appliances accept interface modules — the O2 module adds two FXO line ports inside the PBX itself for around AED 290 — and for two or four lines sitting in the same rack as the system, the module is the cleaner, cheaper answer, and we will say so. The standalone gateway earns its place when the analog world outgrows the chassis: more ports than module slots, devices on another floor or in another building, a hotel wing of room phones, or a fallback design you want independent of the PBX hardware. Both paths are ours to supply. When your counts sit on the border, we quote both, line by line, and you choose with the numbers in front of you. Prices are indicative only — contact our sales for actual market prices.
Two Ports to Thirty-Two — Then Stack Without Limit
The TA FXS ladder runs 2, 4, 8, 16, 24 and 32 ports — TA200, TA400, TA800, TA1600, TA2400, TA3200 — so the box follows the device count, never the other way around. Past thirty-two, you stack: multiple gateways register to the system side by side, which is how large analog estates scale by addition instead of redesign. The manufacturer's own reference deployments include sixty-three 24-port units carrying more than 1,500 analog extensions across a single estate — hotel-tower and hospital-wing territory, running on exactly the boxes on this page. Count your devices, add where you will be in two years, and the ladder names the unit; send the count on WhatsApp and the quote comes back the same business day.

Every quote we send itemises the unit, the installation and the configuration against your actual device and line counts — named in AED before you sign, back the same business day.
Carrier-Grade Where It Counts — the Engineering Buyers Never Hear About
The datasheet lines that decide real-world quality rarely make it into sales conversations, so here they are. Line echo cancellation with selectable tails from 8 to 128 milliseconds — the long-tail territory that tames the awkward copper older buildings serve up. Dynamic jitter buffering on the IP side, so analog calls through the gateway sound like the system's own. A firewall, VLAN support and NAT traversal built into the unit itself. And the fleet pedigree: TR-069 provisioning against any compliant management server, SNMP monitoring, auto-provisioning and full logging — which is why a fifty-branch rollout is a template job from one seat, not a driving schedule. Boring paragraphs like this one are what a quiet, reliable phone estate is actually made of.
How We Install — the Evening Cutover, Not the Outage
First the survey: every analog device, every line, every safety circuit — named on paper before anything is ordered. The gateway is configured and tested on our bench, then installed to run in parallel with the old wiring. Devices move port by port, each with a test call; the elevator and alarm circuits move with your lift and alarm maintainers involved and end-to-end tests passed. Lines cut over last, after hours, with the FXO fallback proven before we pack the tools. Your team arrives the next morning to the same phones on the new system — and the old wiring stays in place until you decide it has earned retirement.
