A contractor's work moves. You win a project, mobilise a site, run it for a season or two, then demobilise and move the crew to the next job. The site office might be a portacabin in the desert, a floor inside a half-built tower, or a fenced laydown yard — none of them places you want to install a phone system, yet head office, the project team, and the field crews all need to reach each other from day one.
Traditional telephony fights this: a phone box per site, a leased line to the camp, an install date weeks out, and hardware written off the moment the project closes — the wrong shape for work that is temporary by nature. Skyline Comms is built for the way contractors actually operate: a fully-managed cloud business phone system from Skyline Cloud that puts your head office, every project site, and your field teams on one phone system in the cloud — where a new site needs nothing but internet, and a finished site leaves no stranded equipment behind. It is designed around these constraints — treating a site as something you switch on and off, not something you build. For the foundations, start with Cloud PBX in Saudi Arabia, the Skyline Comms product page, and the principle of how to connect all your branches without expensive infrastructure.
A new or temporary site needs only internet — nothing to ship or install
This is the heart of it. To bring a site onto the phone system you do not need a PBX box, a phone server, a server room, a leased line, or an engineer visit — only an ordinary internet connection: a fibre line, a 4G/5G router, or a satellite link at a remote camp. Extensions are provisioned remotely from the Skyline Cloud portal, so a new mobilisation can be live in minutes, not weeks. And if a site has no fixed connectivity on day one, the field crew can use the mobile app on their own phones over any network — reachable on the company number before a single cable is run. When the project finishes, you switch the extensions off: no hardware to ship back, nothing stranded on a closed site. For a step-by-step, read open a new site with zero infrastructure.
A mobile app for field staff who are never at a desk
Construction work happens away from the office, so the phone has to follow the person. Each user gets one extension that rings on whatever device suits them — a desk IP phone in the site office, the desktop softphone app for QS and procurement, and the iOS / Android mobile apps for site managers, foremen, and engineers in the field. A site manager keeps one number in the cabin, on the slab, or driving to head office; when a team remobilises elsewhere, their numbers come with them; and everyone works on the company identity, not their personal numbers, so a phone change never loses a contact.
One company number, one dial plan across every site
All your sites and the head office share one unified dial plan, so internal calls behave like a single organisation no matter how far apart the projects are. A short extension reaches any colleague — the next cabin or a camp in another region — and site-to-site and city-to-city internal calls are free, because they never leave your phone system.
Clients and subcontractors reach you on one company number with a single IVR / auto-attendant — "press 1 for projects, 2 for procurement, 3 for accounts" — routed to the right project team, a central desk, or staff mobiles for overflow and after-hours. Because the IVR lives in the cloud, you change the menu or routing once, from the portal, and it applies everywhere instantly. See connect branch offices on one phone system.
No heavy infrastructure between sites
The biggest saving is what you don't build:
- No per-site PBX hardware to buy, rack, or write off at project close.
- No leased lines or MPLS circuits between the office and the camps — sites connect over ordinary internet.
- No long install lead times — a site is added in minutes from the portal.
- No on-site IT — no equipment on site means nothing to maintain or staff.
This is the same argument that decides multi-site networks generally; for the full comparison see multi-site phone systems vs MPLS and leased lines.
Secure, reliable, and Saudi-ready
Running voice over the internet from a remote camp does not mean trading away security or uptime. Voice is encrypted by default — signalling over TLS, audio over SRTP — with an optional private, encrypted VPN tunnel for sites that want voice fully off the public internet. The platform runs with carrier-grade redundancy, and if a site's internet drops, calls fail over to the mobile app or mobile numbers. Saudi numbers and porting come through licensed Saudi carriers, and the platform is designed around Saudi telecom regulation (CST/CITC) and aligned with national data-protection considerations (NCA/PDPL).
Central control and what it costs
Everything is managed from a self-service admin area in the Skyline Cloud portal — no specialist on site, because there is no equipment on site. From one screen head office can add sites and extensions, move a user's number to the next project, change routing and IVR menus, and pull reports per site.
The cost model deliberately moves you off heavy CAPEX: no upfront capital cost, no per-site hardware, and no circuits between sites — just a low, predictable per-seat monthly fee in SAR. Cost scales with the people who need a phone, and when a project ends you simply stop paying for those seats.

Frequently asked questions
How do I get phones on a brand-new site quickly?
Minutes, not weeks. Extensions are provisioned remotely from the Skyline Cloud portal, so there is no line install to wait for and no hardware to ship. With an ordinary internet connection — or just staff mobiles using the app over any network — a site is reachable on your company number the same day it mobilises.
What happens to the equipment when a project ends?
Nothing is stranded. Because there is no PBX or server on site, demobilising a project means switching its extensions off in the portal — no hardware to ship back, no circuit contract to unwind, and you stop paying for those seats.
Can field staff who are never at a desk still be reached?
Yes. Each person has one extension that rings on the iOS / Android mobile app, so a site manager or foreman keeps the same company number in the cabin, on the slab, or driving between sites. Any ordinary internet works — fibre, a 4G/5G router, or a satellite link — and if connectivity drops, calls fail over to mobile numbers.
