The 3CX App • Your office number on every phone

The 3CX Mobile App in Dubai

Your salesperson is across town at a client. The office phone rings — a customer with a live order — and he answers it on his own phone, on the company number, as if he were sitting at his desk. That’s the 3CX app: your office extension on every phone, so your team makes and receives office calls from anywhere — home, the road, another country — and never misses one. Voice, video and chat in a single app, free with your 3CX system. Tell us your team size on WhatsApp.

Your whole office,
in everyone’s pocket.

A desk phone only works at the desk. The 3CX app turns every smartphone, laptop and browser into a full office extension — so wherever your team is, they’re still on the company phone system. Calls go out on the office number. Calls come in wherever they are. And everything — voice, video, chat — runs in one app.

Call from anywhere

Make office calls on the company number from home, a client site, or another country — your callers always see the business, never a personal mobile.

Receive calls anywhere

The office line rings on your phone wherever you are, so a live enquiry reaches your team instead of going to voicemail or ringing out.

Everything in one app

Voice calls, video meetings and chat in a single app on every device — no separate tools, no extra logins, no Zoom or Teams licence.

Call from anywhere

The office number goes
where your team goes

Your people aren’t always at their desks — they’re at client sites, working from home, travelling. With the app, none of that changes how they reach customers.

One number. Every location.

Every call your team makes goes out on the company number, no matter which phone they’re holding or which country they’re in. A customer saved your office line months ago — when your salesperson calls them back from a hotel in another city, that’s still the number that shows up. No personal mobiles handed out, no “use this number instead,” no confusion. It runs over your licensed Etisalat or du line, so it’s your real business number, working from anywhere there’s internet.

Your business number, everywhere

Outbound calls always show the office number — from home, a site visit or abroad — so you look like the established business you are.

No personal numbers handed out

Your team uses the company extension, not their own mobile — so the customer relationship stays with the business, not in someone’s personal contacts.

Works wherever there’s internet

Mobile data, home WiFi, a hotel abroad — if there’s a connection, the app makes office calls. No roaming charges on the business line.

Never miss the call
that pays the bills.

A missed call is a missed customer. The app makes sure that when the office line rings, it reaches a real person — wherever they happen to be that day, in the office or out of it.

The office line rings your phone

Wherever your team is, the office number rings on their phone — so an enquiry at 5pm reaches them on the road, not an empty desk and a voicemail box.

Ring the right people, in order

Ring groups and follow-me mean a call hunts through the right people — desk, then mobile, then a colleague — until someone answers, instead of dropping.

Desk and mobile ring together

The call rings the desk phone and the app at the same time, so whoever’s closest picks up — in the office or out of it.

What the app does

A full office phone, on the
phone in your hand

This isn’t a stripped-down dialler. Everything your team does on a desk phone — and more — is in the app, on every device.

Video calls

Turn any voice call into a face-to-face video call with a tap — between the apps, the desktop and the web client.

Move a call between devices

Start a call at your desk, tap once, and carry it out the door on your mobile — the customer hears nothing change.

See who’s available

Presence shows who’s free, busy or on a call before you transfer — so you don’t send a customer to a dead extension.

Transfer to anyone

Blind or attended transfer to any colleague, on any device, wherever they are — the same as standing at the front desk.

Company directory

The whole company phonebook in your pocket — dial any colleague or saved contact by name, from any device.

Voicemail and recordings

Read and play voicemail in the app, and reach call recordings where your system keeps them — no dialling in to listen.

Every feature works the same on iPhone, Android, Windows, Mac and the web — one experience, every device.

Calls, video and messages
in one place.

Customers don’t only call any more — they message. The 3CX app brings the conversations together, so your team answers every channel from the same place they take calls.

Voice and video meetings

Make calls and host video meetings from one app — no separate Zoom or Teams licence, no extra cost, nothing new for your team to learn.

Website chat and SMS

Live chat from your website and business SMS land in the same app, routed to the right team and answered like any other conversation.

Business WhatsApp in the same inbox

Messages to your business WhatsApp arrive in the same app as your calls — so the channel your customers actually use is handled by your team, and stays with the company.

Every device, set up right

Free with your 3CX —
and working from day one

The app is included with your 3CX system, on every platform your team uses. The part that matters is that it’s set up so it actually works.

On every device, free

iPhone, Android, Windows, Mac and the web browser — the app is free with your 3CX licence, with nothing to buy per user.

Set up across your team

We install and configure it on each device, provision every extension, and test that calls ring properly — so a new joiner is taking calls on day one.

Kept working

Push notifications that ring reliably, kept right as phones and apps update — handled under an AMC, so the app stays dependable.

The app runs as a remote extension of your licensed Etisalat or du line — your real office number, fully within the rules. Want it on your team’s phones? Send your team size on WhatsApp, and our support page covers keeping it running.

What Dubai businesses say about the 3CX app.

★★★★★

"My reps are out all day. Now they make and take office calls on their phones on the company number — customers always reach us, and every call looks like it’s coming from the office. We didn’t hand out a single personal number. Datavox set it up on everyone’s phone in an afternoon."

"Half our team works from home and we kept missing calls. Now the office line rings their phones wherever they are, and a call hunts through the team until someone answers. The difference in missed calls was obvious within a week. Datavox set it up on everyone’s phone and tested it properly."

The 3CX mobile app — your questions answered.

Yes. The app turns each person’s phone into a full extension of your office system, so they make and receive calls on the company number, not their personal one. When they call a customer, the office number is what shows up; when the office line rings, it rings their phone. It works on their existing iPhone or Android — there’s no separate work handset to buy, and no need to hand out personal mobile numbers to customers. We set it up on each device and provision every extension as part of the work.
Yes — that is the whole point of the app. Anywhere there is an internet connection — home WiFi, mobile data, or a hotel in another country — your team makes and receives calls on the office number as if they were at their desk. Outbound calls still show your business number, and the office line still rings their phone. Because the calls travel over the internet to your system and out through your licensed Etisalat or du line, there are no roaming charges on the business line when staff travel. It is genuine office telephony, just not tied to the office building.
It does all of it in one app. Voice calls, face-to-face video calls and meetings, team chat between colleagues, and customer messages — website live chat, business WhatsApp and SMS — all arrive in the same place. You can turn a voice call into a video call with a tap, and host video meetings without paying for a separate Zoom or Teams licence. The idea is one app for every conversation, so your team isn’t switching between half a dozen tools and logins.
All of them — iPhone, Android, Windows, Mac and any web browser. The experience is the same across every device, so someone can take a call on their mobile out of the office, then carry on at their desk on the desktop app or in the browser, with the same number, contacts and history. There’s nothing to install on a server for the apps themselves; we set them up on each person’s devices and make sure they all connect to your system properly.
Yes. The 3CX apps for iPhone, Android, Windows, Mac and the web are free and included with your 3CX system — there is no per-user app fee and nothing extra to buy to put your team on their phones. What you license is the 3CX system itself, sized by how many calls run at once; the apps come with it for everyone. You can see how the system is priced on our pricing page, and we’ll quote your setup in AED for your team size.
Yes — it’s called call flip, and it takes one tap. You can start a call sitting at your desk phone and, as you get up to leave, move it to the app on your mobile without dropping it — the customer hears nothing change. It works the other way too: a call you took on your mobile on the way in can be moved to your desk phone when you sit down. It’s one of the small things that makes the difference between a phone system that ties people to a desk and one that follows them.
A correctly set up 3CX app uses push notifications to wake the phone only when a call comes in, so it rings reliably without sitting in the background draining the battery. When people say an app “never rings,” it’s almost always a setup issue — a phone’s notification settings, or how push is configured on the system — rather than the app itself. That’s exactly the kind of thing we get right when we set it up, and keep right as phones and apps update. If an existing app isn’t ringing, our support page covers fixing it.
Yes. The 3CX app is not a consumer VoIP app like WhatsApp calling — it’s a remote extension of your own office phone system. It connects to your 3CX system, which connects to your licensed Etisalat or du line, so calls go through the regulated, licensed network rather than around it. In other words, the app is simply your office handset running on a smartphone. The TDRA restriction applies to unlicensed consumer calling apps, not to a licensed business PBX extension.
Because your team works on the company’s number and inbox rather than their personal mobiles, the customer relationship stays with the business. When someone leaves, their extension is simply reassigned — the number, the call history and the WhatsApp conversations remain on your system, and the next person picks up where they left off. It avoids the common problem of a departing staff member taking customer contacts and conversations with them on a personal phone. We can talk you through how to set this up cleanly for your team.
