Grandstream PABX System in Dubai — Authorized Dealer & Installer UAE
As an authorized Grandstream distributor in Dubai, PBX Dubai supplies, installs, and supports the complete Grandstream UCM range — from entry-level audio-only systems to enterprise PRI-capable solutions — serving businesses across all UAE emirates.
Grandstream's defining advantage is simple: absolutely zero licensing fees. Every feature — auto-attendant, call recording, video conferencing, and the Wave mobile app — is permanently included. No per-user charges. No annual renewals. No hidden costs. Ever.
The UCM range covers three distinct needs: the UCM6300A audio-only series for cost-focused telephony, the UCM6300 full UC series with built-in HD video conferencing, and the UCM6510 with a built-in E1/T1 PRI port for enterprises retaining existing Etisalat/du digital lines or migrating from legacy PABX systems.
Which Grandstream UCM Series Do You Need?
Grandstream's UCM range is split into three distinct product families. Understanding the difference helps you choose the right system — and avoid overspending or under-specifying.
UCM6300A Series — Audio Only
Pure business telephony at the most competitive price. Full IVR, call recording, Wave mobile app, zero licensing fees — but no built-in video conferencing bridge. The "A" suffix stands for Audio.
Best For: Cost-Focused DeploymentsUCM6300 Series — Full UC + Video
Everything in the Audio series, plus a built-in SFU video conferencing bridge supporting up to 80 HD participants. Higher RAM and storage. No "A" suffix in the model name.
Best For: Modern Offices Needing VideoUCM6510 — PRI / E1 / T1
The only Grandstream UCM with a built-in E1/T1/J1 digital trunk port. For enterprises with existing Etisalat/du E1 lines, or businesses migrating from legacy PABX systems without changing their numbers.
Best For: PRI Lines & Legacy MigrationUCM6300A Series — Professional Telephony, Zero Video Licensing
The "A" series delivers everything a business needs for professional telephony — IVR, call queues, call recording, Wave mobile app, and zero licensing fees — without the added cost of a built-in video bridge. The right choice when Microsoft Teams or Zoom handles your video needs separately.

UCM6510 — The Only Grandstream UCM with a Built-in PRI Port
The UCM6510 is the essential choice for any business in the UAE with an existing E1/PRI digital trunk from Etisalat (e&) or du, or migrating from a legacy PABX system that uses ISDN/PRI trunking. Keep your existing line. Keep all your DDI numbers. Zero disruption. Zero service interruption.
Grandstream UCM6510
Enterprise IP PBX with E1 / T1 / J1 (PRI) Interface · SS7 & PRI Signaling · Rack-Mount
Physical Ports
- 1× E1 / T1 / J1 integrated interface (PRI, SS7)
- 2× FXO ports — analog PSTN trunks
- 2× FXS ports — analog phones / fax (lifeline)
- 2× Gigabit network ports (PoE+ on LAN port)
- USB 2.0 port + SD card slot
- 1GHz quad-core Cortex A9 processor
- 1GB RAM + 32GB flash storage
Ideal For These UAE Scenarios
- Business with active Etisalat or du E1/PRI line — keep all DDI numbers unchanged
- Migrating from Panasonic, NEC, or Avaya PABX using ISDN/PRI digital trunking
- Large enterprises needing up to 30 simultaneous PSTN calls on one E1 circuit
- Businesses using SS7 signaling or legacy digital trunk infrastructure
- High-volume call centers where E1 provides more capacity than multiple SIP trunks
Have an existing E1/PRI line? Our engineers assess your current setup and design a zero-disruption migration plan.
Why Pay Licensing Fees
When You Don't Have To?
Systems like Avaya, NEC, and 3CX charge per-user or annual software license fees that never stop. A 100-user office can spend AED 30,000–60,000 every single year just in license renewals. With any Grandstream UCM — whether it's the entry-level UCM6300A or the enterprise UCM6308 — that ongoing cost is permanently zero. Every feature is included from day one, on every model, forever. Most UAE businesses recover the full hardware cost within the first 12 months.
