- A traditional PBX is a box in your office that you buy, maintain and fix; a cloud PBX is a monthly service over the internet with no central hardware.
- Cloud wins on go-live speed, remote work, scaling, branches, recording and reports; on-premise may suit rare cases such as sites with no stable internet.
- On Klamna the cloud PBX and call center start from SAR 90 per user per month, calls billed per second (SAR, excluding VAT).
For years Saudi companies bought an on-premise PBX with wiring, phones, line cards and a maintenance technician. Today a cloud PBX is the clearer choice for most businesses. Here is the practical difference.
What each one is
A traditional PBX is hardware at your premises: you buy it once, then carry maintenance, updates, power, cooling and backups. A cloud PBX runs on the provider's servers; staff use the browser, a mobile app or a SIP desk phone, and you pay per user per month. Read more in what is a cloud PBX.
Comparison table
| Item | Traditional PBX | Cloud PBX |
|---|---|---|
| Upfront cost | Hardware, cards, wiring, phones | No central hardware; monthly per user |
| Go-live | Often weeks | A few days, depending on the number |
| Maintenance | Yours | The provider's, automatic updates |
| Remote work | Hard | Mobile and desktop apps anywhere |
| Adding a user | Port, device, licence | Minutes from the dashboard |
| Branches | Often one PBX per branch | One system, one number |
| Recording & reports | Add-ons, limited | Built in, with call journey and AI analysis |
| Outages | Hardware or power failure stops calls | Runs on provider servers; agents can answer on mobile |
Real cost
The on-premise "one-time" price hides hardware, installation, maintenance contracts, recording storage, power and eventual replacement. Cloud costs are a per-user subscription, per-second minutes and number fees (by carrier and number type). Example: 10 agents × SAR 90 = SAR 900/month for the cloud PBX with all features; yearly plans include two months free. Prices exclude VAT. See pricing.
Day-to-day features
- Work from anywhere: Android app, Windows/Mac desktop app, iPhone app coming soon. See apps.
- Multi-level IVR, business hours and holidays, hold music, voicemail to email.
- Recording, a call journey diagram per call, reports on peak hours, missed calls and call-back status, plus AI call analysis.
- All the classic PBX features: blind and attended transfer, conference, paging and intercom, call pickup, DND, forwarding, calling permissions and caller ID per extension.
Is it secure?
Choose a CST-licensed provider with data hosted in the Kingdom, clear permissions and two-step verification, aligned with cybersecurity requirements. Etisalna hosts on Alibaba Cloud Riyadh; see trust & security.
When on-premise still fits
Rare cases: a site with no stable internet or mobile data, an internal policy forbidding external systems, or a recently bought PBX you want to use until end of life. Even then you can start one department, such as customer service, in the cloud and compare results.
Comparing over three years
| Item (3 years) | Traditional | Cloud |
|---|---|---|
| Upfront | Hardware + installation + phones | Zero (phones optional) |
| Monthly running | Maintenance/12 + power and storage | Users × SAR 90 |
| Calls & numbers | By carrier | Per second + number fees by carrier |
| Growth or new branch | Extra hardware or ports | Extra users only |
| IT time | Faults and updates | Almost none |

Common migration mistakes
- Copying the old IVR: use the move to shorten and simplify menus.
- Ignoring internet quality: calls need a stable connection more than high speed; prioritise voice on busy networks.
- Switching everything in one day: pilot one department for a week or two first.
- Skipping training: a short session on the app, transfer and hold saves weeks of errors.
- Forgetting calling permissions: decide early who may call international or mobile numbers.
Migration steps
- Inventory extensions, departments, numbers and hours.
- Port or connect your number, or get a 9200 or 800 number through licensed carriers.
- Build IVR, queues, hours, permissions and recording.
- Reuse SIP phones such as Grandstream or Yealink, or use the apps.
- Pilot with one team, then switch fully and review reports.

FAQ
Is cloud cheaper?
Usually, once you count the full on-premise cost. Cloud starts from SAR 90 per user per month with no upfront investment.
What if the office internet goes down?
The PBX keeps running on provider servers; agents answer on the mobile app or calls forward to set mobiles.
Can I keep my number and phones?
In most cases yes for the number; SIP IP phones usually work, analogue phones need an adapter.
How long does migration take?
Setup takes a few days; total time mostly depends on carrier number procedures.
