If you are evaluating 3CX for your UAE office, hotel, clinic or contact centre — this is the no-fluff guide. What 3CX actually is, when to pick it over Avaya / NEC / Yeastar / Grandstream, real UAE pricing, and the after-sales realities most box-traders won't tell you.
What Is 3CX?
3CX is a software-based SIP IP PBX (Private Branch Exchange) phone system. Instead of buying proprietary PBX hardware, you install 3CX software on a Linux server (your own hardware, an Etisalat / du cloud VM, or a 3CX-managed cloud instance). Any SIP-compliant IP phone or softphone works with it — Yealink, Polycom, Snom, Grandstream, Fanvil, or just your laptop and phone via the free 3CX apps.
It is a widely used IP phone system. In the UAE, it is a popular choice for SMEs, mid-market, hotels and call centres that don't want to pay enterprise prices for Avaya / NEC / Cisco features.
The Four 3CX Editions Explained
Edition names below follow 3cx.com (checked 3 November 2026). 3CX changes its editions and prices from time to time, so confirm the current list on 3cx.com; Quicknet states the edition and licence terms in the written quote.
3CX 4SC Free Basic (Self-Hosted)
3CX describes it as a no-cost edition for micro setups, individuals and very small teams: 4 simultaneous calls and core PBX features such as call routing, intercom and basic reporting, for self-hosted deployments only. It suits a trial, a pilot or a very small office.
Cost: No licence cost from 3CX. Setup, IP phones and support depend on the number of users and phones; the price is confirmed in a written quote after a site survey.
3CX Basic
Core telephony without CRM, contact-centre or AI features, available on every deployment model: hosted by 3CX, self-hosted or on-premise. 3CX prices it below PRO. Best for offices that want a reliable phone system and no extras.
Cost: See the 3CX price list on 3cx.com. The total depends on the user count, phones and SIP trunks; the price is confirmed in a written quote after a site survey.
3CX PRO
The workhorse — advanced call-centre tools, CRM integration, AI voicemail transcription, queue management, IVR and reporting, on every deployment model. Most UAE SMEs and mid-market deployments use this.
Cost: Licensed per system by simultaneous calls (SC), not per user; see the 3CX price list on 3cx.com. The price is confirmed in a written quote after a site survey.
3CX AI Edition
3CX's edition for larger organisations and high-call environments, with AI transcription and other AI features, on every deployment model. Best for contact centres, multi-site businesses and busy call environments.
Cost: Priced by simultaneous calls; see the 3CX price list on 3cx.com.
Why "Simultaneous Calls" Not "Users" Matters
This is the single biggest 3CX mistake we see. 3CX licences by simultaneous calls (SC), not by user count. A 20-user office where only 4 people are on the phone at the same time only needs a 4 SC licence. A 100-user office where 16 people are on the phone simultaneously needs 16 SC.
Rule of thumb for UAE businesses: Plan for 20-30% of your headcount on the phone at peak times. So:
- 10 users → 4 SC sufficient
- 20 users → 4–8 SC
- 50 users → 8–16 SC
- 100 users → 16–32 SC
- 250 users → 32–64 SC
- Call centre with 30 agents → 32 SC (1:1 since all agents are on calls)

| Feature | 3CX PRO | Avaya IP Office | NEC SL2100 | Yeastar P-Series |
|---|---|---|---|---|
| License model | Per-system (SC) | Per-user | Per-user | Per-user |
| IP phone lock-in | No (any SIP) | Yes (Avaya) | Yes (NEC) | No (any SIP) |
| Mobile + web softphone | Free, included | Add-on licence | Add-on licence | Free, included |
| Built-in video conferencing | Yes, free, 250 ppl | Add-on (Spaces) | No | Limited |
| WhatsApp / live chat | Yes, included | No | No | P-Series only |
| Hotel PMS integration | Limited | Strong | Strong | Add-on module |
| Call recording | Yes, included | Add-on | Add-on | Yes |

When 3CX Wins
- SME 10-200 users — strong price/feature value in this range
- Call centres — full call centre suite at SME pricing
- Multi-site businesses — bridging multiple offices simply
- Remote / hybrid teams — free apps, WebRTC softphone, mobile
- Open-standards organisations — no vendor lock-in
- Companies replacing Skype for Business — Teams Direct Routing is documented by 3CX; confirm the edition and call count it requires in 3CX's documentation
When 3CX Is NOT the Right Choice
- Large hotels (200+ rooms) — Avaya / NEC have stronger PMS integration with Opera, Protel, IDS
- Strict legacy compatibility — companies with hundreds of digital handsets they won't replace
- Companies needing 24/7 vendor-direct support contracts — Cisco / Avaya have stronger global SLA networks
- Highly regulated financial / government — sometimes mandate specific vendors
What Drives the Cost of a UAE 3CX Project
Example: 30-user SME office in Abu Dhabi migrating from old NEC analog PBX to 3CX PRO.
- 3CX PRO 8 SC licence (year 1, priced on 3cx.com)
- 30 × Yealink T31G IP phones
- UAE cloud VM (Etisalat) for hosting (yearly)
- Etisalat SIP trunk (8 channels + DID porting) (yearly)
- Installation, configuration, training, cutover
- Optional first-year AMC
- The licence, hosting and SIP trunk repeat each year; the price is confirmed in a written quote after a site survey.
The After-Sales Reality (Most Box-Traders Won't Tell You)
3CX is software. Software needs ongoing care:
- Security patches — quarterly updates fix CVEs; without them you're exposed
- Upgrade migrations — 3CX major version (V18 → V20) requires planned migration
- SIP trunk changes — Etisalat / du change SIP signalling occasionally; you adjust
- Configuration drift — staff change, IVR menus need updating, queues need tweaking
- Backup & restore — need verified backup procedure, tested annually
- Anti-fraud — international call fraud attempts hit every public-facing PBX; need active monitoring
This is the gap between a "trading-only" supplier and a supplier that supports what it installs. Quicknet bills AMC explicitly because we deliver explicit value: same-day response, 2-hour on-site response for AMC customers in Abu Dhabi, configuration changes included, quarterly health reviews, security audits. If your supplier just sells you the licence and disappears — you'll be in trouble within a year.
Frequently Asked Questions
Can I install 3CX myself?
Yes — 3CX provides good documentation and the installer is straightforward. But: configuring SIP trunks, IVR, queues, security hardening and IP phone provisioning needs hands-on experience. Many UAE SMEs that try a DIY install end up asking for help. The "savings" of self-install are usually modest — for a much rougher experience.
Does 3CX work with Etisalat eLife / du Home?
3CX needs SIP trunks (a business product). Etisalat eLife and du Home are residential / SoHo and don't provide SIP. Get Etisalat Business or du Business with SIP — your operator can arrange it for you.
What happens if my server / cloud goes down?
Some 3CX editions support a standby fail-over server that takes over automatically (check which on 3cx.com). On-premise without standby — you have downtime until you restore from backup (typically 30 mins-2 hours with a tested backup procedure). For mission-critical setups, always use an edition with standby.
Can I keep my existing phone numbers?
Yes — Etisalat and du allow number porting from your old PABX to your new SIP trunks. We coordinate the porting (timing depends on the carrier) and time it for the cutover weekend so customers experience zero number change.
What is a 3CX system?
3CX is a software-based phone system (IP PBX) built on open SIP standards, running in the cloud or self-hosted, with mobile, web, video calling, live chat and CRM integration apps — a modern replacement for a traditional PBX.
How does 3CX licensing work?
3CX is licensed by the number of simultaneous calls, not the number of users — that is, how many calls are in progress at the same time. Since your whole team is rarely on a call at once, choosing the right number of simultaneous calls saves significantly compared to per-user licensing.
Should I deploy 3CX in the cloud or self-hosted?
Both are possible. Cloud deployment removes the need for on-site hardware and suits distributed teams (see Cloud PBX UAE). Self-hosted deployment gives you full control over your own server. We recommend whichever best fits your infrastructure and budget.
How much does 3CX cost in the UAE?
Cost depends on the edition, the number of simultaneous calls, the deployment option (cloud or self-hosted), and the phones and SIP lines required. We assess your actual need and send a clear, correctly sized quote with no overpaying — contact us for a tailored quote.
Do you provide support after installation?
Yes. We offer manufacturer-warranty guidance, updates and annual maintenance contracts (AMC): support that continues after the sale, which makes the difference over the long term.
Is 3CX free?
3CX offers a Free Basic edition for micro setups: 4 simultaneous calls, core PBX features, self-hosted only, at no licence cost. Paid editions (Basic, PRO and AI) are priced by simultaneous calls. A business that needs more calls, CRM links, contact-centre tools or local support normally buys a paid edition; Quicknet confirms the current edition and licence terms in the written quote.
Which 3CX editions are available in 2026?
3CX's editions on its pricing page in November 2026 are Free Basic, Basic, PRO and AI. Licences are priced per system by the number of simultaneous calls, hosting by 3CX is optional, and each edition sets which features are included. 3CX changes its editions and prices from time to time, so confirm on 3cx.com; Quicknet checks the current editions against your office size at the free survey and puts the exact edition in the written quote.
Does 3CX need its own server, or can it be hosted?
Either. 3CX can run on a server or virtual machine you control, in a cloud you rent, or in a hosting service. The sizing depends on the number of simultaneous calls and features such as call recording, and 3CX publishes the requirements for each version. Quicknet recommends the option at the survey and installs and tests it.
How many extensions can a 3CX system have?
3CX licenses by simultaneous calls, and its price list shows the maximum number of users or extensions for each call tier: for example up to 40 users on 8 simultaneous calls and up to 80 on 16. Confirm the current limits on 3cx.com; Quicknet checks the extension count against the licence before you order.
Which IP phones work with 3CX?
3CX publishes a list of supported phones that can be provisioned automatically, and Yealink, Fanvil and Grandstream are among the brands commonly used with it. Always check the exact model on 3CX's list before buying. Quicknet supplies and provisions the phones; see our Yealink and Fanvil pages.
Can 3CX work with Grandstream phones or a Grandstream UCM?
Grandstream desk phones can be used as handsets on a 3CX system if the model is on 3CX's supported list, and Grandstream FXO and FXS gateways can connect analogue lines and phones to it. A Grandstream UCM is a separate PBX, so you choose either 3CX or a UCM as the main system. Quicknet compares them for your site at the free survey.
Can 3CX do IVR menus, hot-desking, click-to-call and CRM links?
Yes. 3CX has a call-flow designer for IVR and auto-attendant menus, and it offers hot-desking, click-to-call and integrations with CRM tools such as HubSpot. Which of these are included depends on the edition, so confirm the edition when you scope the project. Quicknet configures and tests the call flows with you.
Can 3CX connect to analogue lines or a GSM line?
Yes, through a gateway. An FXO gateway connects analogue lines, an FXS gateway connects analogue phones and fax machines, and a GSM gateway connects a mobile SIM. Quicknet supplies the gateway and sets it up on the 3CX system. See our VoIP gateway pages.
Bottom Line
For UAE SMEs (10-200 users), 3CX is a strong price/feature option in 2026 — open standards, low licensing, modern features. For mid-market 200-500 users, 3CX PRO or the AI edition is competitive with Avaya / NEC and typically has a lower TCO.
The catch: 3CX is software, and software needs ongoing care. Pick a supplier who treats your phone system as a relationship, not a transaction.
