Grandstream PBX Dubai — Every Feature In. No Per-User Licence.
Your last phone system quote had a line item called "licence". This page exists so your next one doesn't.
The Grandstream UCM6300 — the PBX, or EPABX as most buyers in this region search it — is one compact appliance that runs the whole phone system: extensions, IVR, recording, queues, video meetings, hotel PMS and mobile apps, every feature included, permanently. One purchase. No per-user licence on the core system, this year or any year after.
Vector Digital Systems is an authorized Grandstream distributor in Dubai — UCM6301 to UCM6308A in genuine stock, installed on licensed Etisalat or du lines, configured before it reaches your rack, supported by the same engineers after handover.
- UCM6301–UCM6308A — supply, installation, migration
- Etisalat & du SIP trunk configuration
- Wave app & RemoteConnect setup — free Basic plan
- Call-center queues & hotel OPERA PMS integration
- NEC / Panasonic replacement — numbers kept, zero downtime
The Phone System Where the Price Is Close to the Whole Price
A Grandstream UCM6300 includes every software feature permanently — auto attendant, call recording, voicemail-to-email, IVR, call queues, CRM integration, video meetings and hotel PMS — with no per-user licence on the core system. The appliance price is close to the whole price. Year two costs nothing for the system itself.
That is a different economic model from most of what gets quoted in this market. Software phone systems elsewhere bill annually — per user, per simultaneous call, or per feature pack — so the system you bought keeps billing you for owning it. The UCM's model is older and simpler: you buy it, you own it, and the features stop being a subscription.
Even the management is free: GDMS provisions and monitors every device from a browser, and GWN.Cloud runs the network from one screen — both permanently free, both configured for you before handover. Weighing this against Yeastar or 3CX licence maths? The three-way comparison, no favourites →
What can carry a fee — stated before you sign
The core system never has a per-user licence. Three optional items can carry a fee, and we name them in the quote if they apply to you: UCM RemoteConnect plans above the free Basic tier (annual, per appliance, for remote teams larger than 10 users), SoftwareUCM (Grandstream's self-hosted software edition — the same UCM platform on your own server or VM — if you choose it over an appliance), and large IPVideoTalk meeting plans beyond the free tier. Nothing else hides anywhere.
Which UCM Is Yours — Every Model, Every Number
The question most buyers open with is the wrong one — "which is the biggest?" The right one is quieter: which model matches your Tuesday. All six run the same software with every feature included, so the only real decision is capacity.
| Model | Users | Concurrent calls | FXO/FXS ports | Best for | Indicative price |
|---|---|---|---|---|---|
| UCM6301 | 500 | 75 | 1 / 1 | Small offices, startups | from ~AED 850 |
| UCM6302 | 1,000 | 150 | 2 / 2 | Full UC with video — most offices | from ~AED 979 |
| UCM6302A | 500 | 75 | 2 / 2 | Audio-focused — no video conferencing | quoted per setup |
| UCM6304 | 2,000 | 300 | 4 / 4 | Medium-large businesses | quoted per setup |
| UCM6304A | 1,000 | 150 | 4 / 2 | Audio-focused enterprise | from ~AED 1,500 |
| UCM6308A | 1,500 | 200 | 8 / 2 | Audio-focused flagship — no video conferencing | from ~AED 2,500 |
Indicative pricing: Prices are indicative and move with stock availability and exchange rates. The exact current price comes via the WhatsApp quote — same working day.
One distinction that confuses buyers: the UCM6308 (video flagship) and the UCM6308A (audio-focused) are different units — 3,000 users and 450 calls with video conferencing on the 6308, versus 1,500 users and 200 calls on the audio-focused 6308A, which costs less for offices that don't need video. The same relationship holds down the A-series (6302A/6304A) versus the full 6302/6304 models. We quote both where both make sense — you choose whether video is worth the difference.
Running an older UCM6200 or a UCM6510? The 6200 series (up to 800 users, 100 calls, no GDMS, no RemoteConnect) and the discontinued 6510 still work — we maintain both. Expansion, though, means moving to the 6300 series: we migrate your configuration, extensions and call flows across with zero downtime, and your numbers never change.
One box instead of four — when the site needs the network too. Some locations don't need a PBX; they need the whole rack. The GCC6020 and GCC6021 fold the phone system, VPN router, next-generation firewall and managed PoE switch into one appliance: 50 users and 12 concurrent calls out of the box, with paid upgrades that scale it toward 1,000 users — same UCM software, same features, inside the box that also runs the network. Deep-packet-inspection firewall, WireGuard/OpenVPN/IPsec VPN, multi-WAN failover — and current firmware adds USB 4G/5G dongle failover and ZeroTier, so a branch on a single building line stays reachable the day the fibre drops. The GCC6021 goes further with hot-standby high availability and 24 PoE ports for the phones and access points themselves. For branches, clinics and warehouses that would otherwise buy four devices from four vendors, we quote this alongside the UCM and you choose — the networking side of that family is on our GWN networking page.
Capabilities the UCM6300 Gained Quietly — All Included, All Current
Grandstream ships features through firmware faster than its marketing pages update. These are the ones that change what a Dubai business gets from the same appliance — all present on current UCM6300 firmware (series 1.0.33, May 2026), all included:
WhatsApp on the PBX
Customer WhatsApp messages arrive in the same inbox as calls, answered from the UCM portal by your team — or by a chatbot you configure. One screen for the 9 AM call and the 9 PM enquiry.
Microsoft Entra ID sign-on
Staff log into the phone system with their existing Microsoft 365 accounts — single sign-on, users synced automatically, no extra passwords to manage or leak.
Direct OPERA PMS integration
The UCM talks to Oracle OPERA directly — no middleware server between your PMS and the phone system. Check-in activates the room phone; checkout wipes it; the minibar posts itself.
Recordings to your own storage
Call recordings archive automatically to S3-compatible cloud storage — yours, not a vendor's. Compliance-grade retention for clinics, law firms and finance, under your control.
Skill-level call routing
Queue proficiency routing sends the caller to the right person by measured skill, not just whoever is free — the Arabic caller to the Arabic speaker, the technical question to the technician.
Your old phones join automatically — even Cisco and Polycom
Third-party SIP phones provision onto the UCM with zero configuration — and since firmware 1.0.31 that includes Cisco 7800/8800 series and Polycom Edge and VVX handsets. The phones you already own join the new system without an engineer touching each one. Migration cost drops by the phones you keep.
Multi-factor login for remote users (fw 1.0.31)
Wave app logins can require an email verification code on top of the password — multi-factor authentication for your remote team, included free. The security layer remote work usually pays extra for.
Least Cost Routing (fw 1.0.27)
With carrier rates configured, the system picks the cheapest line for every outgoing call automatically — international calls route by price, not by habit. The savings show up in the first Etisalat or du bill.
Odoo CRM integration (fw 1.0.27)
Calls pop the customer's Odoo record on screen before anyone answers, and outbound calls start with one click inside Odoo. Salesforce, HubSpot, Zoho and Microsoft Dynamics connect the same way.
How the UCM Connects to Your Etisalat or du Lines
Somewhere between choosing a new system and signing for it, every owner asks the same quiet question: will my lines still work? Yes — the UCM6300 runs on licensed SIP trunks from Etisalat (e&) or du, the UAE's two approved carriers. We handle the whole path: the application, trunk registration, number mapping, inbound and outbound routing, and testing on the live line before anything goes into your rack.
Still on analog or ISDN? Most models carry built-in FXO ports, so your existing lines plug straight in while you migrate to SIP at your own pace. No forced switchover date, no dead-air weekend — the old lines retire when the new ones prove themselves.
Your existing numbers move with you: we port them onto the new trunk, typically two to four weeks with your trade licence and account documents. Customers notice nothing except faster answers.
And if your office internet is ordinary shared fibre, the UCM is built for it — its jitter handling keeps calls clean through packet loss that would break a lesser system (rated to 50% packet loss). Voice gets priority on the network we design, either way.
The System Stays in Your Office. Your Team Doesn't Have To.
The Wave app turns any phone or laptop into your office extension — same company number on the customer's screen, calls, chat, voicemail and video meetings from anywhere. UCM RemoteConnect is the secure relay that connects those remote extensions to your office PBX without VPNs or open ports: the Basic plan is free for up to 10 remote users, and larger remote teams move to annual per-appliance plans that we size and quote with the system — never as a surprise later.
GDMS is how the whole fleet gets managed: every PBX, phone, gateway and access point provisioned, monitored and updated from a browser — free, permanently. A phone shipped to your branch configures itself when it plugs into the network we prepared for it — in this region the carrier layer is not neutral, and we engineer around it. And it is how we watch your system after handover: most issues get fixed remotely before you notice them.
Two Offices. One Company. One Phone System.
Call your own branch from head office, and on separate systems the phone treats it as an outside call — billed, every time, between desks that belong to the same company. On the UCM6300 it doesn't have to be that way.
Two UCMs link directly over a SIP peer trunk: extensions at one site dial extensions at the other by short number, calls between your offices cost nothing, and LDAP sync merges the directories so every name and extension shows on every phone at every site. Eventless BLF lets reception at one site see who's free at the other before transferring. And for estates of three sites or more, the CloudIM add-on syncs every UCM into one network — one dial plan across cities or borders, with the Wave app carrying any extension anywhere.
We run this exact design between our own Dubai and Kochi desks every working day — the same topology we install for you. The full multi-site design story is on our branch office connectivity page.
What Your Callers Hear When Every Agent Is Busy
On an old system, a caller who hits a busy line hears hold music until they give up — and the lost order never appears on any report. On the UCM6300, they hear their position in the queue and can press one key for a callback instead of holding. The abandoned-call number on Monday's report drops the same week — and nobody on your team did anything differently.
The rest of the module is what dedicated platforms charge separately for: multi-level queues with skill-based routing, live agent dashboards, supervisor listen-whisper-barge for training, wallboards, per-queue recording, and exportable reports on answered, abandoned and callback numbers per agent and per queue. The UCM6308's 450 concurrent calls cover most Dubai service operations without a second platform.
And the newest layer: on current firmware the system transcribes calls and produces AI call summaries (rolling out through 2026) — every recorded call becomes searchable text, and the Monday report reads itself.
One Platform, Tuned to How Your Building Works
Hotels: it is 6:30 AM and three hundred guests asked for a wake-up call — the system makes them all, in Arabic or English, and reports which rooms didn't answer. The UCM series is an Oracle-validated OPERA interface (official approval, May 2026) — direct integration with no middleware: check-in activates the room phone, housekeeping updates room status from the handset, minibar posts to the folio, checkout wipes the guest's data, and guests can set their own wake-up calls through the IVR. Properties without a PMS get the built-in Local PMS instead — room availability calendar, guest email invoicing, self check-in and check-out by email, even hourly room rentals for serviced apartments. Pair it with GHP room phones for the full estate. The complete hospitality approach is on our hotel phone systems page.
| Industry | How the UCM6300 gets configured for it |
|---|---|
| Call centers & service desks | Queues with callback, agent dashboards, wallboards, per-queue recording and reports |
| Clinics & healthcare | Appointment-line queues, call recording for instructions, paging and emergency routing |
| Schools & education | Multi-site dial plans, bell scheduling, and the Announcement Center — one dial code broadcasts a voice message to any extension group, from classrooms to the whole campus |
| Real estate | Wave app on every agent's phone, CRM screen-pop, call recording on viewings |
| Staff accommodation & hostels | Youth Hostel Mode — rooms split into billed units, group billing per bed, wake-up scheduling per unit |
| Retail & warehousing | DECT cordless coverage, branch dial plans, intercom and paging |
| Multi-site enterprises | One dial plan across branches, GDMS-managed fleet, hot-standby redundancy |

Grandstream PBX in Dubai — the Questions We Get Every Week
What is a Grandstream PBX (EPABX) system?
A Grandstream PBX — also searched as a Grandstream EPABX — is the UCM6300 series IP PBX: a compact appliance that runs your entire business phone system — extensions, call routing, IVR menus, call recording, queues, video meetings and mobile apps — with every feature included and no per-user licence on the core system. In Dubai, UCM6300 systems start from around AED 850 for the small-office UCM6301, supplied and installed on licensed Etisalat or du lines.
How much does a Grandstream PBX cost in Dubai?
Indicative pricing: the UCM6301 for a small office starts around AED 850, the UCM6302 around AED 979, the UCM6304A around AED 1,500, and the UCM6308A for large enterprises around AED 2,500 — every software feature included, no annual licence for the core PBX. Desk phones start around AED 99. Prices are indicative and move with stock availability and exchange rates; the exact current price comes via the WhatsApp quote, same working day.
What is the difference between UCM6301, UCM6302, UCM6304 and UCM6308?
It is mostly scale — all four run the same software with every feature included. UCM6301 covers a small office (up to 500 users, 75 concurrent calls). UCM6302 adds full unified communications with video support (1,000 users, 150 calls). UCM6304 serves medium-large businesses (2,000 users, 300 calls), and UCM6308 is the video flagship (3,000 users, 450 calls, hot-standby capable). The A-series variants (6302A, 6304A, 6308A) are the audio-focused editions — no video conferencing, lower price, with their own capacities from 500 to 1,500 users. The free survey sizes the right one — buying bigger than needed costs money forever, buying smaller costs calls.
What is the difference between the UCM6300 and the older UCM6200 series?
The UCM6300 is the current generation: up to 3,000 users and 450 concurrent calls against 800 and 100 on the UCM6200, built-in video meetings, UCM RemoteConnect for secure remote work without VPN, GDMS cloud management, and high-availability standby on the top models — none of which the 6200 series had. If you run a UCM6200 today, the system still works — we maintain it — but expansion means moving to the 6300 series, and we migrate configuration, extensions and call flows across with no downtime.
Are there any Grandstream licence fees to know about?
The core PBX has none — every UCM6300 feature is included permanently, and the GDMS and GWN.Cloud management platforms are free forever. Three optional items can carry a fee, and we name them in the quote before you sign: UCM RemoteConnect plans above the free Basic tier (annual per-appliance plans for larger remote teams — Basic covering up to 10 remote users is free), SoftwareUCM if you choose Grandstream's self-hosted software — the UCM on your own server or VM — instead of an appliance, and large IPVideoTalk meeting plans beyond the free tier. The appliance on your wall never bills you in year two.
What is UCM RemoteConnect — and is it free?
UCM RemoteConnect is Grandstream's secure cloud relay that connects your remote extensions — the Wave app on a phone, a laptop at home, a branch in another country — to your office PBX without VPNs or port forwarding. The Basic plan is free and covers up to 10 remote users with 2 concurrent remote calls. Larger remote teams move to annual per-appliance plans, which we size and quote with the system so the cost is never a surprise.
What is the Grandstream Wave app?
Wave is Grandstream's free app for mobile and desktop that turns any device into your office extension: make and receive calls on the company number, chat with colleagues, transfer calls, check voicemail and join video meetings — from anywhere with internet. Your salesman answers the office line from a viewing and the customer sees the company number, never a personal mobile. It pairs to the system with a QR code and works with UCM RemoteConnect.
Does a Grandstream PBX work with Etisalat and du lines?
Yes — fully. The UCM6300 connects to licensed SIP trunks from Etisalat (e&) and du, the two approved UAE providers, and we handle the ordering, registration and testing. If your office still runs analog or ISDN lines, the built-in FXO ports on most models connect those directly while you migrate to SIP at your own pace — no disruption, no forced switchover date.
Which areas in the UAE does Vector Digital Systems cover for Grandstream PBX?
Vector Digital Systems designs, installs and supports Grandstream PBX systems across the United Arab Emirates — all seven emirates: Dubai, Abu Dhabi, Sharjah, Ajman, Fujairah, Ras Al Khaimah, and Umm Al Quwain — as well as Al Ain. In Dubai we cover the main business districts and communities including Business Bay, Downtown Dubai, Dubai International Financial Centre (DIFC), Dubai Marina, Jumeirah Lakes Towers (JLT), Sheikh Zayed Road, Deira, Bur Dubai, Al Quoz, Al Barsha, Barsha Heights, Al Garhoud, Al Jaddaf, Oud Metha, Ras Al Khor Industrial Area, Al Nahda, Mirdif, Jumeirah, International City, Discovery Gardens, Jumeirah Village Circle (JVC), Arabian Ranches, Motor City, Dubai Internet City, Dubai Media City, Dubai Production City, Dubai Outsource City, Dubai Silicon Oasis, Dubai Healthcare City, Dubai Maritime City, Dubai Festival City, Dubai World Trade Centre, Dubai Investment Park, Dubai South, Jebel Ali and Jebel Ali Free Zone (JAFZA). In Abu Dhabi we serve the city plus Khalifa City, Mohammed Bin Zayed City, Musaffah, Industrial City of Abu Dhabi (ICAD), Yas Island, Saadiyat Island and Al Reem Island. Sharjah coverage includes Sharjah Industrial Area, SAIF Zone, and Al Nahda, Sharjah; we also serve Ajman Free Zone (AFZ), Ajman Industrial Area, RAK Free Trade Zone, and the Port of Fujairah. Same-day on-site response across Dubai, with remote GDMS-based support available UAE-wide as of 2026.
Do you export Grandstream PBX systems from Dubai?
Yes — we export UCM6300 systems and phones from Dubai to Saudi Arabia, Qatar, Oman, Iraq, Jordan, Lebanon, Yemen, Syria, Turkey, Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Armenia, Georgia, Bangladesh, Pakistan, Afghanistan, Uganda, Kenya, Nigeria, Cameroon, Egypt, Ethiopia, Ghana, Mauritania, Mauritius, Morocco, Mozambique, Rwanda, Senegal, South Africa, South Sudan, Sudan, Tanzania, Tunisia, Zambia, Zimbabwe, Algeria, Burkina Faso, Côte d'Ivoire, Malawi, Burundi, Djibouti, Togo, Benin, Gabon, Chad, Seychelles, and Angola. Systems are configured and tested in Dubai before dispatch, shipped with export documentation, and brought live remotely on the licensed carrier in each country. Trade pricing is available for resellers and integrators buying in volume.
Is a Grandstream PBX good for call centers?
Yes — the call-center module is built in, not bolted on: multi-level queues with skill-based routing, callback instead of holding, live agent dashboards, supervisor listen-whisper-barge for training, wallboards, and per-queue call recording with exportable reports. The UCM6308 handles 450 concurrent calls, which covers most Dubai service operations without a separate platform.
Can a Grandstream PBX integrate with hotel PMS?
Yes — the UCM6300 integrates directly with Oracle OPERA property management systems, with no middleware box: check-in activates the room phone, wake-up calls schedule from the PMS, housekeeping status updates from the room handset, minibar posts to the folio, and checkout wipes the guest's data. Paired with GHP hotel room phones, it is our default hospitality platform. The full approach is on our hotel phone systems page.
Can you migrate our old NEC or Panasonic system to Grandstream?
Yes — it is the most common replacement we install. Your numbers port across unchanged, cabling and analog phones carry over through gateways, and the old system keeps working until the Grandstream platform has passed every test — there is no quiet day in between. The detailed paths are on our NEC end-of-life page and Panasonic end-of-life page, or send your current model on WhatsApp and we will tell you exactly what the migration involves.
What is GDMS and is it really free?
Yes, genuinely free. GDMS (Grandstream Device Management System) is Grandstream's cloud platform for provisioning, configuring, monitoring and updating every Grandstream device you own — PBX, phones, gateways, access points — from a browser, with no licence fee, forever. Zero-touch provisioning means a phone shipped to a branch configures itself when plugged in, and it is how we monitor and maintain your fleet remotely after handover.
Do Grandstream PBX systems work with Microsoft Teams?
Yes — through Microsoft Teams Direct Routing, your team makes and receives normal office calls inside Teams using your existing UAE numbers, on the UCM6300 and licensed Etisalat or du lines. We configure the session border controller, the SIP trunk and the Teams admin side as one project — Teams where staff want it, desk phones and apps everywhere else.
