Quick answer
In brief
An office telephone system, whether an analogue PABX, an on-premise IP PBX or a hosted service using VoIP, connects a few incoming lines to the extensions across a business. Vertex Automation surveys the premises, specifies the system in plain English and installs it in Dubai offices, with cabling run alongside the data network and every extension tested and documented at handover.

How it works
Designed as one joined-up system, not a list of devices.
01
PABX, IP PBX and VoIP, in plain terms
The terminology causes more confusion than the systems deserve, so here's the plain version, and our guide to what PABX, IP PBX and VoIP actually mean takes the same ground more slowly. A PABX, or PBX for short, is the equipment that lets a few incoming lines serve many internal extensions. An IP PBX does the same job over your data network instead of dedicated telephone wiring. VoIP is not a product but a method: carrying calls over an internet connection instead of a traditional line. These are not competing options you must choose between blindly; most systems installed in Dubai offices today are IP-based and use VoIP for outside calls. What matters is not the label but whether the system is sized and configured for the way your office takes calls.
02
Call flows before equipment
That's where we start. Before any equipment is specified, we map how calls should move: who answers first at reception, where a call goes when that desk is busy, which teams need their own numbers or hunt groups, who wants voicemail delivered to email, and which staff need their extension to follow them to a mobile. A system specified around those answers stays useful for years. A system specified from a features brochure rarely does.

Handsets, softphones and the lines behind them share the building's cabling, so the phone design and the network design are settled in the same conversation.

03
Survey, specification, then installation with the fit-out
Every installation follows the same method as the rest of our work: a survey of the premises and any existing wiring, a written specification in plain English, installation timed with the office fit-out so cabling goes in before partitions and finishes close up, then configuration, testing of every extension and a documented handover.

What it gives you
What a system specified properly gives you
Hardware is the means. These are the things you notice once the system is live.
01
A system you understood before you bought it
Our recommendation arrives as a plain-English specification: what type of system, how many extensions, what happens to your existing wiring and numbers, and why. It's brand-agnostic and sized to your premises, whether that is a four-desk studio or a full floor, so you are approving a plan you can actually read, not a parts list.
02
Calls that land where they should
Reception answering, hunt groups, an auto-attendant where it genuinely helps, voicemail to email, extensions that reach staff on a mobile when they are out. Features are configured around your call flows at commissioning, not left at factory defaults for someone to puzzle over later.
03
Installed with the fit-out, not after it
Telephone points are planned on the same drawings as the network and the rest of the low-voltage work, and cabled in the same first-fix pass. There is no second contractor cutting into finished walls once the office is already decorated and occupied.
04
Documented and ready to grow
Every extension is numbered, labelled and recorded at handover. When desks are added or the office is repartitioned, new points are an addition to a documented plan, not a rediscovery of what an earlier contractor left in the ceiling void.
Scope
What a telephone installation includes
Set at design stage, from the property and your priorities, never from a fixed package.
- Site survey of the premises, existing wiring and call-flow requirements
- Plain-English system specification: analogue PABX, on-premise IP PBX or hosted options
- Extension planning and numbering for desks, reception, meeting rooms and back of house
- Telephone cabling run alongside the data network, or reuse of existing runs that test sound
- Handset supply, installation and configuration at every desk
- Reception routing, hunt groups, auto-attendant and voicemail setup
- Mobile and remote extensions for staff who work away from the office
- Coordination with your telecom operator on lines, numbers and SIP connectivity
- Testing of every extension and call path before handover
- As-built documentation, labelling and agreed aftercare
Project detail
Telephony is one strand of a low-voltage fit-out, not a trade on its own, and that is how we install it. The telephone system shares its planning with the data network, the door intercom and any office automation on the project: one set of drawings, one containment strategy, one rack, one handover file. Most telephone installers stop at the handsets; because we also install the network the phones depend on, the system is designed with that network rather than around it, and a weak switch or a congested link is caught at the survey, not blamed after the first dropped call.
In a new office fit-out, telephone points are planned at first fix alongside the network cabling, with desk positions and the reception layout agreed on the drawings before partitions close, which is when this work is cheapest and tidiest to do. In an existing office, we survey what is already installed: an IP system can often run on a healthy existing network with very little new cabling, an ageing analogue PABX can usually be replaced without losing the numbers your staff already give out, and wiring that tests sound gets reused.
In Dubai
Telephone System in Dubai
Climate, regulation and the way this city builds all shape the specification, before any equipment is chosen.
Most Dubai office fit-outs raise the telephone question at some point, usually late. We are based in Al Quoz and install across Dubai, in standalone offices, retail units, clinics, warehouses and villa offices, and our advice is the same everywhere: decide the phone system when the network is being decided, so cabling, rack space and desk positions are planned once instead of revisited after the decoration is finished.
Phone lines, numbers and SIP connectivity in the UAE are provisioned through licensed telecom operators, and installing the system is a separate piece of work from providing those lines. We design and install everything on your side of that boundary and coordinate with the operator on the rest, including planning a changeover so the new system is proven before the old one is disconnected.
Questions
PABX, IP PBX and VoIP, answered plainly
PBX and PABX are the same thing: the exchange equipment that lets a few incoming lines serve many internal extensions. An IP PBX is a PBX that runs over your data network instead of dedicated telephone wiring. VoIP is a method, not a product: carrying calls over an internet connection. A modern office system is typically an IP PBX using VoIP for outside calls, either as equipment on your premises or hosted by a provider. The label matters far less than whether the system fits how your office answers the phone.
It depends on a short list of factors: how many users and handsets, whether the system is on-premise or hosted, the condition of any existing cabling, the call features you actually need, and the aftercare arrangement you want. We don't publish price tables, because two offices of the same size can need genuinely different systems. After a survey we quote the specific job, itemised, so you can see what each part costs.
Usually, yes. Your numbers sit with your telecom operator, not inside the old equipment, so replacing the system doesn't by itself change them. We plan the changeover with the operator: the new system goes in and gets tested first, then the lines move across. Nobody is left hoping the office is reachable on Monday morning.
Internal calls on an on-premise IP PBX run over your local network, so extension-to-extension calling continues even when the internet connection is down. Outside calls carried over that connection are affected, which is why we assess the office network and its connectivity as part of the survey. The phone system is never looked at in isolation. Hosted systems depend more heavily on the connection, and that trade-off is part of the on-premise versus hosted decision we walk you through.
At the same time as the network, before first-fix cabling goes in. Telephone and data points share routes, containment and rack space, so deciding both together means one cabling pass and no surface trunking added after the walls are finished. If your fit-out is already underway, it's still worth deciding now: the later it is left, the fewer tidy options remain, and we'll tell you which ones are still open.
