Complete IP Telephony Portfolio

From IP PBX selection and SIP trunk provisioning to phone installation, IVR configuration, number porting, and ongoing AMC — we handle every layer of your business phone system.

IP PBX Supply & Installation

Supply and install on-premise IP PBX appliances — Yeastar S-Series and P-Series, Grandstream UCM6300 series, or 3CX software PBX on a dedicated server — sized for your extension count with room to grow. Configure extensions, ring groups, call routing schedules, voicemail, and call recording before handover. All systems come with UAE warranty and local support.

VoIP SIP Trunking

Connect your IP PBX to UAE-licensed SIP trunk providers — replacing expensive PSTN landlines with cost-effective VoIP channels. Configure Direct Inward Dialling (DID) numbers, set channel capacity for concurrent calls, and set up failover routing to a secondary trunk if the primary fails. Businesses typically see 40–60% reduction in monthly call costs versus PSTN.

IP Desk Phones & Handsets

Supply and configure Yealink, Grandstream, Cisco, and Fanvil IP desk phones — from basic single-line handsets to executive colour-screen models with BLF keys showing colleague availability at a glance. Wall-mount and conference room speakerphones for meeting rooms. All phones are provisioned automatically from the PBX with zero manual configuration on each device.

IVR Auto-Attendant & Call Routing

Build professional IVR menus — "Press 1 for Sales, Press 2 for Support" — with time-based routing that directs callers differently during business hours versus after hours and public holidays. Configure hunt groups, round-robin ring distribution, overflow routing, and call queues with hold music and position announcements for inbound call management.

Mobile Softphones & Remote Extensions

Install softphone apps (Zoiper, Grandstream Wave, 3CX app) on employee smartphones and laptops — giving remote and travelling staff a full office extension on their mobile, with the same extension number, call recording, and transfer capabilities as a desk phone. Internal calls between extensions are free regardless of location, eliminating mobile call costs for internal communication.

How We Deliver Your IP PBX Project

1

Communication Assessment

Audit your current phone system — extension count, call volumes, incoming numbers, IVR requirements, and pain points. Assess your network infrastructure to confirm it can carry VoIP traffic with acceptable quality (QoS), and identify any VLAN or firewall changes needed to prioritise voice traffic before any hardware is ordered.

2

System Design & Proposal

Select the right PBX platform for your scale and budget, size the SIP trunk channel count for your peak concurrent call volume, and design the extension plan, IVR menu structure, ring groups, and call recording policy. Provide a detailed itemised proposal with equipment, licensing, and installation costs before any work begins.

3

Installation & Number Porting

Install and configure the PBX, provision all extensions and IP phones via auto-provisioning, configure IVR and routing rules, set up softphone apps for remote users, and activate SIP trunks. Coordinate number porting from your current provider — existing numbers transfer to the new SIP trunk so callers reach you on the same numbers with no disruption.

4

Training & Handover

Train reception and admin staff on the PBX web interface, call transfers, voicemail management, and call recording access. Train IT team on extension management. Provide call flow documentation and admin login credentials. Confirm AMC schedule and support contacts before go-live. We stay available for the first week post-cutover to resolve any teething issues immediately.

IP PBX Solutions Across Industries

Offices & Corporate

Centralised IP PBX serving all desk staff with IVR, ring groups per department, call recording for compliance, executive DND and assistant routing, and mobile softphones for remote workers — all accessible from a single management console by IT or office admin without telephony specialist knowledge.

Call Centres & Support Teams

Inbound call queuing with position announcements and hold music, round-robin agent distribution to equalise workload, supervisor monitoring and whisper coaching for training, call recording for quality assurance, and wallboard statistics showing queue depth and agent availability in real time — without a dedicated call centre platform subscription.

Multi-Branch Businesses

Interconnect offices across Dubai, Abu Dhabi, and the wider UAE with a single IP PBX or distributed PBX trunked over your VPN — internal calls between all branches are free, staff can transfer callers to any branch extension seamlessly, and a single IVR number can route callers to the appropriate location without knowing branch-specific numbers.

Hotels & Hospitality

In-room guest handsets registered as extensions on the hotel PBX — enabling wake-up call scheduling, room-to-room calls, direct dial to reception and housekeeping, and integration with Property Management Systems (PMS) for automatic check-in/out extension enabling. IVR service menus provide a professional guest experience without additional staffing.

Healthcare & Clinics

Separate ring groups for appointments, emergencies, and billing — with time-based routing directing after-hours callers to an on-call answering service or emergency message. Nurse call integration via IP phone extensions in patient rooms, call recording for complaint management, and IVR appointment confirmation options reducing reception workload.

SMBs & Startups

Right-sized IP PBX from 5 to 50 extensions with a professional IVR giving callers the impression of a larger organisation — routing to sales, support, or accounts automatically. Free softphone extensions for team members working remotely or on mobile, with call recording enabled from day one for training and dispute resolution.

The Zeronix IP Telephony Advantage

40–60% Lower Call Costs

SIP trunks cost significantly less per channel than PSTN lines, international call rates via VoIP are a fraction of PSTN rates, and internal calls between all extensions — including remote staff on softphones — are completely free. Most businesses recover the full cost of an IP PBX installation within 12–18 months from call cost savings alone.

VoIP-Ready Network Assessment

We assess your network before installation — checking bandwidth, latency, and jitter, and configuring QoS (Quality of Service) to prioritise voice traffic over data. VoIP on an improperly configured network sounds poor and drops calls. We fix the network first, so your phone quality is excellent from day one.

Scale Without Rewiring

Adding a new extension on an IP PBX requires a network port and a new IP phone — no additional copper pairs to the PBX cabinet, no engineer visit to patch a physical port. Extensions can be added by your IT team from the web console in minutes, making IP telephony dramatically faster and cheaper to scale than traditional systems.

Seamless Number Porting

We manage the entire number porting process — your existing UAE landline numbers transfer to your new SIP trunks without disruption. Porting is coordinated to occur outside business hours where possible, and we configure failover routing during the porting window so no incoming call is missed during the transition.

Professional IVR from Day One

We script and record IVR greetings for you — professional voiceover in English and Arabic as required — and programme the full call routing logic including business hours, after-hours, holiday schedules, and queue handling. Your callers experience a polished, professional system from the first call, not a generic default setup.

Fast Remote AMC Support

Most IP PBX issues — misconfigured routing, failed SIP registration, extension not ringing — are diagnosable and fixable remotely within 2 hours. We have secure admin access to your PBX for rapid remote resolution without waiting for an on-site visit, so your phone system is back up quickly when it matters.

Frequently Asked Questions

A traditional PBX routes calls over copper PSTN lines using analogue or ISDN circuits — physical wiring determines extension count and calls travel over the telephone network. An IP PBX routes calls over your data network using VoIP technology, meaning calls travel as data packets over your LAN and internet connection. This enables far more features (advanced IVR, call recording, mobile softphones, conference bridges), dramatically lower call costs for local and international calls, and much simpler scaling — adding extensions requires no additional physical wiring, just a network port and an IP phone.
We supply and install Yeastar S-Series and P-Series appliances, Grandstream UCM6300 series, 3CX software PBX (installed on a Windows or Linux server), and Cisco IP Phone infrastructure across Dubai and the UAE. We also supply IP desk phones from Yealink, Grandstream, Cisco, and Fanvil. We recommend the right platform based on your extension count, required features, IT team's comfort level managing the system, and budget.
Yes. We handle number porting — transferring your existing UAE landline numbers (Etisalat/du DID numbers) to SIP trunk providers so your business retains its established phone numbers. The porting process typically takes 5–10 business days and is coordinated to minimise any interruption to incoming calls. We configure the new IP PBX to receive calls on your existing numbers before porting is finalised, and provide failover routing during the transition window.
Most businesses in the UAE see a 40–60% reduction in monthly call costs when switching from PSTN to VoIP SIP trunking — particularly significant for businesses making frequent international calls, where VoIP rates are a fraction of PSTN per-minute charges. Internal calls between all extensions, including remote staff on mobile softphones and staff in other offices, are completely free over the IP network. Line rental for SIP trunk channels is also typically lower than PSTN line rental. Most businesses recover the IP PBX installation cost within 12–18 months from savings alone.
Yes. Our IP PBX AMC covers PBX and phone firmware updates, SIP trunk provider management, extension adds/moves/changes, IVR menu and routing updates, call recording storage management, system health monitoring, and remote and on-site support for faults. Most IP PBX issues are resolved remotely within 2 hours — we have secure admin access to your system for rapid diagnosis without waiting for a site visit. We also provide periodic system reviews to optimise routing rules as your business evolves.

Still Paying PSTN Rates for Every Call?

Most businesses in the UAE overpay for phone calls and underutilise their phone system. Talk to a Zeronix engineer — we'll assess your current setup and show you exactly what an IP PBX would save and enable.
