Question 1

What is the difference between an FXS and an FXO gateway?

Accepted Answer

Direction. FXS gives a phone line to a device — fax machines, analog phones, door phones and elevator intercoms plug into FXS ports and receive dial tone from your IP system. FXO takes phone lines from the wall — your Etisalat or du analog lines plug into FXO ports and their calls flow into the system. Devices need FXS; lines need FXO. Tell us what you are connecting and the model picks itself.

Question 2

Can a fax machine really work on a VoIP phone system?

Accepted Answer

Yes — done properly. Fax over the internet is fragile when treated as an ordinary call, which is why the TA gateways carry T.38 fax support and why our installation configures it specifically. The fax the bank insists on keeps working, on one FXS port, for years.

Question 3

How do we keep the elevator emergency line when the phone system changes?

Accepted Answer

One FXS port. The lift phone plugs in and behaves exactly as before — it can dial out, it can be reached, and the building's requirement stays satisfied. We test it live during installation, because an elevator line is not the place for assumptions.

Question 4

We have a hotel with analog phones in every room. Do the phones need replacing?

Accepted Answer

No — that is exactly what the high-density FXS gateways exist for. The TA1600 carries 16 rooms, the TA2400 twenty-four, the TA3200 thirty-two, and units stack for larger properties. The room phones and the building wiring stay; the system behind them becomes modern. Send the room count for a stacked quotation.

Question 5

Can we move to an IP phone system but keep our existing Etisalat lines?

Accepted Answer

Yes — an FXO gateway takes your existing analog lines into the new system, so the numbers customers have saved keep ringing while everything behind them changes. TA410 for 4 lines, TA810 for 8, TA1610 for 16. Many offices run this way for years; others use it as the bridge while moving to SIP trunks at their own pace.

Question 6

What does a GSM gateway actually do for a business?

Accepted Answer

It puts SIM cards inside the phone system. Calls to the company's mobile numbers ring on the PABX — answered, transferred, recorded and reported like any call, so a salesman's missed call is no longer invisible. Outbound, least-cost routing sends calls through the cheapest path automatically, and the system can send SMS in bulk. One box, real money saved monthly.

Question 7

Should I buy the classic TG or the 4G TG-L GSM gateway?

Accepted Answer

By destination. UAE deployments take the 4G generation — the LTE-module TG200, TG400 and TG1600 — supplier code TG-L — in our Dubai stock — because the older 2G/3G network layers here have been retired. Export destinations where 2G/3G still runs are honestly served by the classic TG units at friendlier prices. Name the country and we name the generation.

Question 8

Do these gateways only work with Yeastar phone systems?

Accepted Answer

No — they speak standard SIP and serve any IP phone system: Yeastar P-Series and Software PBX, 3CX, Grandstream UCM, Asterisk and others. The gateway you buy today moves with you if the system behind it ever changes.

Question 9

Is PRI still relevant, and what about BRI?

Accepted Answer

Where an E1/PRI contract carries the company's calls — still common in enterprises and across export markets — the TE100 and TE200 connect it to the IP world at 30 and 60 channels. BRI is now a niche: the TB200 and TB400 serve the legacy ISDN connections that remain, and we say honestly when an FXO or SIP path serves the same need for less.

Question 10

What does a Yeastar gateway cost in Dubai?

Accepted Answer

Anchors from the table: TA400 about AED 570 and TA800 about AED 810 for small FXS jobs, TA2400 about AED 2,220 for density, TA1610 about AED 2,650 for sixteen lines, TE200 about AED 3,810 for dual PRI, and the 4G TG400L about AED 3,520 — indicative only. WhatsApp your counts for the exact configured quotation.

Question 11

I am migrating from a Yeastar S-Series. Which gateways do I need?

Accepted Answer

Whatever your S-Series modules carried: analog phones and fax on FXS modules become a TA FXS gateway; analog lines on FXO modules become a TA FXO gateway; GSM modules become a TG unit. Send a photo of your S-Series rear panel on WhatsApp and the replacement gateway list comes back mapped port for port.
