PABX Support Dubai —
3CX, Yeastar, NEC,
Grandstream & Panasonic.
Your 3CX licence expired and the phones went quiet. Or the Yeastar Linkus app stopped working and staff can't reach calls from their phone. Or you have an NEC system that nobody in Dubai will touch anymore. Whatever the issue — Vector Dubai has handled it before, and we'll handle yours. Whether you need PBX support in Dubai, office phone system support, or PABX troubleshooting across any brand, the process is the same: describe the problem, we diagnose it.
What's the Issue Right Now?
Pick the situation closest to yours. Each one has a specific cause and a specific fix. None of them need a new phone system — just someone who knows where to look.
3CX Licence Expired or Expiring
System stopped working. Calls not going through. Or a renewal notice arrived and nobody is sure what to do with it.
Yeastar Linkus Not Working
Mobile app stopped connecting. Staff can't make office calls on their phones. Linkus Cloud subscription probably expired.
Grandstream UCM Issue
Extensions dropping. SIP trunk connecting and disconnecting. IVR not set up. System was installed but something isn't right.
NEC System — No Support
NEC exited the market. The installer won't respond. Nobody local seems to know the system. You still need it to work.
Panasonic PABX Programming
Need to add extensions. Reprogramme the IVR. Set up call routing. The original installer is gone and programming requires specific tools.
SIP Trunk or IVR Not Working
Etisalat or du SIP trunk not connecting. IVR greeting needed. Call routing wrong. Applies to any brand of PABX.
3CX Support Dubai — Licence Renewal, Subscription Upgrade & Technical Fix
3CX runs on an annual subscription — not a one-time purchase. When that subscription expires, the system keeps working through a short grace period and then shuts down. Completely. Staff can't make calls. Can't receive calls. Can't use the app. It happens in the middle of the working day without warning if nobody tracked the renewal date. We renew 3CX licences same day in most cases — WhatsApp us the renewal notice and we'll handle the rest. 3CX authorised partner Dubai. 3CX distributor Dubai since 2010.
VDS is a 3CX authorised partner in Dubai. We renew both standard annual subscriptions and enterprise upgrades. If your 3CX subscription expired this morning, WhatsApp us — we can have it renewed within a few hours once payment is confirmed. We cover all licence sizes from small offices on 8 simultaneous calls up to enterprise deployments. As a 3CX reseller Dubai we handle renewals for both direct clients and channel partners.
3CX Licence Renewal Dubai — Subscription Renewal, Annual Renewal & Upgrade
3CX licences are based on simultaneous calls, not number of extensions. A 16SC licence means 16 calls can happen at the same time — not that only 16 people can use the system. Most Dubai SMEs with 20–50 staff run comfortably on a 16SC or 32SC licence. When we renew, we check whether your current licence size still fits your actual usage — and tell you honestly if it doesn't. If your 3CX licence expired or your 3CX subscription expired, the fix is the same: renew 3CX licence Dubai through the partner portal. 3CX annual renewal, 3CX licence upgrade Dubai, 3CX Pro licence, and 3CX Enterprise licence renewals are all handled through the same process.
| Licence Type | Simultaneous Calls | Best For | Renewal Approx. |
|---|---|---|---|
| 3CX Standard / SMB | 8–16 SC | Small offices, 10–30 staff | AED 800–1,800 / year |
| 3CX Pro | 16–64 SC | Medium businesses, call recording needed | AED 1,800–6,000 / year |
| 3CX Enterprise / AI | 32–256 SC | Large offices, call centre features, CRM | AED 6,000+ / year |
3CX Technical Support Dubai — Configuration & Fault Fixing
Licence renewals are the most common call. But 3CX also develops technical issues — extensions stop registering, the SIP trunk disconnects from Etisalat or du, the mobile app loses connection, or the IVR gets corrupted after a version upgrade. These are all fixable remotely without touching the server in person.
3CX Licence & Subscription Issues
- Annual renewal — Standard, Pro, Enterprise, AI tiers

- 3CX SIP trunk not connecting Dubai: registration failure diagnosis
3CX IVR & Call Flow Setup
- Digital Receptionist (IVR) setup: recording upload, menu routing, time-based rules
- Business hours vs after-hours routing — two separate call flows
- Ring groups and hunt groups: sequential or simultaneous ringing
- Call queues: hold music, queue announcements, agent availability
- Voicemail-to-email: audio file forwarded to inbox when calls are missed
- CRM integration: calls popping up customer records in HubSpot or Zoho
- 3CX reconfiguration Dubai: full system rebuild after server migration or data loss
- 3CX installation Dubai: new deployments on-premise or cloud-hosted
- 3CX hosted Dubai: managed hosting with VDS handling updates and monitoring
Yeastar Support Dubai — Linkus Cloud Renewal, P-Series & S-Series Configuration
Yeastar systems have two separate subscriptions that buyers often confuse. The PBX licence is a one-time purchase for the hardware or a recurring fee for the cloud version. The Linkus Cloud Service is a separate annual subscription that powers the mobile app, remote extensions, and the web client. When Linkus Cloud expires, staff lose mobile access — even though the core phone system keeps working. The two look like the same problem but have different fixes. When Yeastar Linkus Cloud expires, the fix is straightforward — Yeastar Linkus Cloud expired Dubai is one of the most common calls we receive. Yeastar subscription renewal Dubai is processed through the Yeastar partner portal. Vector Dubai is a Yeastar partner Dubai with certified engineers.
Yeastar Linkus Cloud renewal Dubai: The Linkus Cloud Service renews annually per Yeastar's partner portal. When it expires, the Yeastar mobile app disconnects for all users simultaneously. Re-activation is instant once the renewal is processed. Vector Dubai is a certified Yeastar partner — we renew Linkus Cloud on P-Series and S-Series systems across Dubai and UAE. Yeastar PSE support Dubai: the self-hosted PSE licence renews annually and shuts down the PBX when it expires — same urgency as 3CX.
● Yeastar P-Series Support Dubai
- Yeastar PSE (self-hosted) and P-Series Cloud: subscription renewal and activation
- Linkus Cloud Service renewal — mobile app, web client, remote extension access
- Extension management: add, remove, reconfigure without IT support

Grandstream UCM Support Dubai — UCM6510, UCM6308 Configuration, SIP Trunk & Gateways
Grandstream UCM systems have no licence fees and no annual subscription — which is one reason they're popular. But that also means there's no vendor support portal to call when something breaks. The UCM6308, UCM6510, and earlier UCM6100 series are all running across Dubai offices. Most issues come up 3–6 months after installation — when the initial setup needs tuning as the network changes or staff numbers grow. Grandstream PABX support Dubai and Grandstream PBX support Dubai cover all UCM series from the UCM6104 through to the UCM6510. When a Grandstream UCM not working Dubai call comes in, the fault is usually network-side, not hardware.
Grandstream UCM Configuration Support
- UCM6510 and UCM6308 — post-install configuration and optimisation
- Extension registration issues: SIP credentials, IP restrictions, firewall rules
- Etisalat SIP trunk on Grandstream UCM — codec negotiation, registration interval
- du SIP trunk setup on UCM — outbound and inbound routing with DIDs
- IVR (Digital Receptionist) setup: professional recording upload, menu routing
- Call queue configuration: hold music, queue announcements, agent timeout
- Remote extension setup: staff working from home accessing UCM extensions
- Grandstream UCM upgrade and factory reset — data backup and restore
- Grandstream UCM6510 support Dubai: enterprise deployments up to 2,000 users
- Grandstream UCM6308 support Dubai: mid-market office systems, SIP trunk config
- Grandstream UCM configuration Dubai: post-install tuning, extension tree, trunks
- Grandstream extension not registering Dubai: firewall rules, SIP ALG, NAT settings
- Grandstream SIP trunk not working Dubai: codec mismatch or registration expiry
- Grandstream IVR setup Dubai: Digital Receptionist menus, time conditions, recordings
Grandstream VoIP Gateway Support Dubai
Grandstream makes more than IP PBX systems. Their FXO, FXS, PRI, and GSM gateways are widely used for connecting legacy PSTN lines, analogue handsets, and mobile SIMs into IP phone systems. These gateways need careful configuration — particularly the PRI/ISDN gateways used when businesses have legacy ISDN lines from Etisalat.
- GXW4232 PRI gateway: ISDN PRI to SIP conversion — E1 line to UCM or 3CX
- GXW4104 FXO gateway: analogue PSTN line integration with IP PBX
- GXW4216 FXS gateway: analogue handsets and fax machines on IP network
- GSM/LTE gateway: Grandstream GXW series — SIM card based VoIP for outbound
- Grandstream VoIP gateway configuration Dubai: FXO, FXS, PRI, GSM — all models
- Grandstream FXO gateway Dubai: GXW4104 analogue PSTN line to SIP conversion
- Grandstream PRI gateway Dubai: GXW4232 E1/ISDN to SIP — Etisalat ISDN line migration
- Grandstream UCM Etisalat SIP trunk: e& SIP registration, codec, DID routing
- Gateway not registering to PBX: SIP credentials and network path troubleshooting
Grandstream distributor Dubai: Vector Dubai is an authorised Grandstream distributor. When a Grandstream UCM needs a replacement part — a phone, a gateway, or a new UCM unit — we supply it from stock at our International City location. Most common Grandstream models are available same day.
NEC PABX Support Dubai — SL2100 & Legacy UNIVERGE Systems
NEC made a decision at the end of 2024 to exit the on-premises PBX hardware business globally. Systems already installed continue to work — NEC didn't switch anything off remotely. But they stopped developing new hardware, stopped releasing firmware updates, and stopped providing global support contracts. What that means for businesses in Dubai is that the responsibility for supporting these systems has moved entirely to the local partner network. Vector Dubai is one of the few companies still actively servicing NEC SL2100 and the legacy UNIVERGE series. If you are looking for an NEC PABX alternative Dubai — or need to understand NEC PABX end of support Dubai implications for your system — we give you a plain answer, not a sales pitch.
NEC SL2100 — still active and serviceable: The NEC SL2100 is the most recent NEC PABX model and is still in active use across Dubai. Vector Dubai continues to supply SL2100 hardware, SIP trunk licences, expansion cards, and digital handsets where stock is available. If your SL2100 needs support, a licence added, or an expansion — we can help. If the system is aging and migration becomes the better option, we'll give you an honest recommendation rather than keeping you on a system that's losing support.
● NEC SL2100 Support Dubai
- SIP trunk licence addition: NEC SL2100 requires a separate SIP trunk licence — supply and activation
- Etisalat and du SIP trunk registration on NEC SL2100 — configuration and testing
- Extension programming: add, remove, rename extensions on the SL2100
- NEC digital handset supply: ITK-6D, ITK-12CG, ITK-24CG — from remaining UAE stock
- IVR auto attendant setup on SL2100: call flow design and configuration
- NEC SL2100 not working: fault diagnosis, card check, power supply
- System backup and restore: configuration preserved before any major change
- NEC telephone system support Dubai: SL2100 and all handset generations
- NEC PABX maintenance Dubai: AMC options for ongoing SL2100 support
- NEC phone system not working Dubai: fault diagnosis — power, cards, trunk, extensions
- NEC PABX repair Dubai: line card, power supply, and handset-level fault resolution
● NEC Legacy UNIVERGE Support & Migration
- UNIVERGE SV9100 and SV8300: configuration support for systems still in operation
- NEC ASPIRE series: smaller legacy systems, still in use in older Dubai buildings
- Fault diagnosis: line card failure, power unit, trunk card — repair or replace
- NEC PABX migration Dubai: when migration makes more sense than continued support
- Migration options: Yeastar P-Series or 3CX — both retain existing phone numbers and extensions
- Honest assessment: we tell you if the system is worth supporting or not
- NEC UNIVERGE SV9100 support Dubai: configuration, fault diagnosis, expansion
- NEC SV8300 support Dubai: legacy system programming and fault support
- NEC ASPIRE support Dubai: older KX-NCP equivalent systems still running in Dubai
- NEC to Yeastar migration Dubai: number and extension preservation, minimal downtime
- NEC to 3CX migration Dubai: hosted or on-premise, same day number porting possible
- Replace NEC PABX Dubai: honest assessment of when migration beats continued support
- NEC PBX support Dubai: all generations from ASPIRE through to SL2100
On NEC migration: Not every NEC system needs to be replaced. The SL2100 is a solid platform and many will keep running without problems for years. The question is whether you can still get support and parts when something fails. We'll assess your specific system and give you a straight answer — stay on it, add a maintenance arrangement, or plan a migration. NEC PABX end of support Dubai means the manufacturer is out of the picture — but that doesn't automatically mean you need a new system today. No pressure either way.
Panasonic PABX Support Dubai — KX-NS700, KX-NS300, KX-NS500 & KX-NS Support
Panasonic dominated the Dubai SME phone system market through the 2000s and 2010s. The KX-NS700 and KX-NS300 are still running in hundreds of offices. The problem is that Panasonic programming requires specific PC Programming Software — most installers have moved on and no longer have it configured. Adding extensions, reprogramming the IVR, or adjusting call routing requires someone who still has the tools and knows the platform. Panasonic telephone system support Dubai, Panasonic PABX maintenance Dubai, and Panasonic KX-NS support Dubai all fall into this category.
● Panasonic KX-NS Series Support Dubai
- KX-NS700, KX-NS500, KX-NS300: extension add, rename, feature assignment via PC Programming
- Panasonic KX-NS SIP trunk configuration: Etisalat and du SIP line registration
- Auto attendant (DISA) programming: call flow, time routing, department menus
- IVR recording upload: professional audio file format conversion and integration

- SIP extension card add: expand KX-NS700 with additional IP extensions
- KX-NCP series (older systems): programming and fault support
- Panasonic to Yeastar migration: when expansion needs exceed what KX-NS can handle
- Panasonic PABX not working Dubai: fault diagnosis from power supply to card replacement
SIP Trunk Configuration Dubai & IVR Setup — PABX Not Working, Extensions, VoIP
Every PABX in the UAE connects to the outside world through either Etisalat (e&) or du. The SIP trunk — the digital line that carries calls — is licensed by the carrier and configured at your end. When it's correctly configured, it's invisible. When it's not, nothing works: no outbound calls, no inbound calls, no IVR answering. VoIP telephony in the UAE is only legally permitted through licensed carriers — Etisalat and du. Every SIP trunk VDS configures is compliant with Telecommunications and Digital Government Regulatory Authority (TDRA) guidelines.
Etisalat SIP Trunk Configuration Dubai
- Etisalat (e&) SIP trunk registration on 3CX, Yeastar, Grandstream UCM, NEC, Panasonic
- Correct codec settings: G.711 vs G.729 — Etisalat specific requirements
- DID routing: multiple Etisalat numbers mapped to different extensions or departments
- SIP trunk not connecting after Etisalat line installation: credential and IP verification
- Inbound calls working but outbound not: outbound routing rules fix
- Etisalat e& business SIP: configuration differs from residential SIP — we know the difference
- Etisalat SIP trunk setup Dubai: new line activation and PABX-side configuration
- Extension not registered Dubai: most common fault after a SIP trunk or network change
- IP phone not registering Dubai: SIP credentials, server address, NAT traversal fix
- PABX extension not working Dubai: systematic fault isolation — trunk, extension, handset
du SIP Trunk Setup & IVR Configuration Dubai
- du SIP trunk registration on all major PABX brands — same-session remote support
- du registration interval and authentication type: specific to du's UAE network
- IVR setup Dubai: recording supply (professional voice), upload, menu routing
- Auto attendant setup Dubai: "Thank you for calling — press 1 for sales, press 2 for accounts"
- Time-based routing: office hours to live agent, after hours to voicemail or emergency
- PABX IVR programming Dubai: any brand, any complexity, remote or on-site
- du SIP trunk configuration Dubai: registration credentials, port settings, codec config

- VoIP licence renewal Dubai: all subscription-based PABX platforms
- Office phone system support Dubai: any brand, remote or on-site, across all 7 emirates
- PBX support Dubai: Grandstream, Yeastar, 3CX, NEC, Panasonic — one team
- Telephone system repair Dubai PABX: hardware fault, line card, power supply
- Office phone system licence expired Dubai: diagnosis and same-day renewal options
On VoIP and TRA compliance: VoIP calls in the UAE must route through licensed carriers — Etisalat or du. Systems that bypass UAE carriers using international SIP providers are not TRA compliant and risk service disruption. All SIP trunk configurations VDS delivers use licensed UAE carrier lines. TRA approved VoIP Dubai means routing calls through Etisalat or du — not international SIP providers. When office phones are down, SIP trunk not connecting Dubai is the most common cause.
PABX Support Across Dubai Industries
We support systems installed by other companies. The brand and the original installer don't matter — if your phone system has a web interface or a programming port, we can work with it.
DIFC, Business Bay, Downtown Dubai
3CX and Yeastar are the dominant PABX platforms in Dubai's financial district offices. 3CX renewal urgency is highest here — a lapsed licence means regulatory-critical calls go unanswered. We keep renewal tracking for channel partners and direct clients in this sector.
Schools, Colleges, Training Centres
Dubai schools run 3CX and Grandstream UCM widely. Renewal cycles align with academic years and get missed during summer. We've renewed 3CX licences for multiple Dubai schools — Sherborne, and others — often on short notice when the system goes down in September.
Hotels, Serviced Apartments, F&B
Hotels in Dubai often run NEC or Panasonic systems from installation 10–15 years ago. The original installer is usually unreachable. When a system fails mid-occupancy, the GM needs someone who knows the platform, not someone who will learn it on the premises' time.
Al Quoz, Deira, Jebel Ali, DIP
Grandstream UCM is the most widely installed PABX for Dubai trading and logistics companies. It was installed, configured, and then largely left alone. When something breaks — SIP trunk, extension, IVR — the trading company needs it fixed fast without a long IT procurement cycle.
Moving Office or Upgrading Your Phone System?
Two situations that come up regularly — and both need a telephony engineer, not a general mover. If your office is relocating or your phone system is reaching end of life, VDS handles the technical side so your phones work in the new location from day one.
Moving Office — Phone System Relocated and Reconfigured
When a business moves office, the PABX has to move with it — and it does not simply plug back in. The new location has a different network, a different IP range, and often a different SIP trunk configuration for the new premises. IP phones need reprovisioning. Extensions that were mapped to physical locations need remapping. The IVR may need updating with a new number or new routing.
VDS handles PABX relocation Dubai for 3CX, Yeastar, Grandstream UCM, NEC SL2100, and Panasonic KX-NS systems. Telephone system relocation Dubai, office phone system relocation, IPBX shifting — whatever you call it, the job is the same: your phones need to work in the new office from day one. We disconnect the system at your current office, attend the new location on the day of your move, and have all phones registered and calling before your first working day in the new space. SIP trunk reconfiguration for Etisalat or du at the new address is included.
What PABX relocation covers: Physical disconnection at current office · Transport coordination with your movers · Reconnection and network integration at new office · IP phone reprovisioning across all extensions · SIP trunk reconfiguration for new premises · IVR and call routing update if numbers or departments change · Test call on every extension before handover
Replacing an Old System — Upgrade to IP PBX
Panasonic KX-TDA, KX-TDE, and older NEC systems are reaching end of support. Parts are becoming unavailable. When a hardware fault hits a system this age, repair is sometimes not the right answer. An office move is also the right moment to evaluate whether the existing system should be upgraded rather than relocated.
VDS assesses whether relocation or replacement makes better financial sense for your specific system and scale. Telephone system upgrade Dubai, IP PBX upgrade Dubai, office telephone system upgrading — if the current system is holding the business back, we supply and install 3CX, Yeastar P-Series, or Grandstream UCM — migrating your existing extensions, IVR, and call flows to the new platform. The old system is decommissioned cleanly. Staff training is included at handover.
Common upgrade paths: Panasonic KX-TDA/TDE → 3CX or Yeastar P-Series · NEC SL1000/SL2100 → Grandstream UCM or Yeastar · Analogue PABX → IP PBX with SIP trunk · On-premise PABX → 3CX hosted with mobile app access
Tell us your current system, your new office location, and your move date. We'll confirm scope and availability the same day.
PABX Support Across Dubai & All UAE Emirates
3CX licence renewals and Yeastar Linkus Cloud renewals are processed remotely — location makes no difference. Technical support for configuration issues starts remotely via TeamViewer or web browser, on-site only when the fault requires physical access. On-site visits cover all seven emirates with same-day or next-morning availability in Dubai.
Covering: DIFC · DMCC / JLT · Business Bay · DAFZA · JAFZA · Dubai Silicon Oasis · Dubai Internet City · International City
PABX & IP PBX Export — Middle East & Africa
Vector Dubai supplies 3CX licences, Yeastar P-Series, Grandstream UCM, and NEC SL2100 hardware to channel partners, system integrators, and resellers across the Middle East and Africa. Most supply orders ship within 2–3 working days from our Dubai location. Licence keys for 3CX and Yeastar are delivered electronically within hours of order confirmation.
Gulf & Middle East
3CX and Yeastar are the fastest-growing PABX platforms across the Gulf. Saudi Arabia and Kuwait represent the largest renewal volumes outside the UAE. Grandstream UCM6308 and UCM6510 ship regularly to GCC system integrators. NEC SL2100 remains active in Oman and Bahrain where the platform has strong hotel and government penetration. Electronic licence delivery means Gulf partners receive 3CX and Yeastar activations within hours.
East & Southern Africa
Grandstream UCM and Yeastar S-Series are the dominant platforms for East African system integrators sourcing through Dubai. Kenyan and Tanzanian partners order UCM6308 for commercial office deployments. 3CX is growing in Nairobi's financial and NGO sector. Yeastar GSM gateways are active in markets where SIM-based calling is more cost-effective than fixed SIP. Air freight and sea freight to Mombasa and Dar es Salaam available.
West & Central Africa
Nigerian distributors are among the highest-volume Grandstream UCM buyers through Dubai. Lagos-based system integrators regularly order UCM6308 and GXP2170 phones for commercial deployments. Grandstream's no-licence model is particularly compelling in West Africa where ongoing subscription costs are a barrier. 3CX is growing in the Francophone West African market for businesses with French-language IVR requirements. Air freight priority available for urgent orders.
What Our Clients Say
Dubai businesses with PABX systems supported, renewed and running.
"Our 3CX licence expired on a Saturday morning — all incoming calls were failing by 9AM. We found Vector Dubai through Google, sent a WhatsApp, and they had the licence renewed and the system back before 11. No site visit needed. The whole thing took under two hours. We're now on their renewal tracking so this cannot happen again."
"Our Grandstream UCM kept dropping the Etisalat SIP trunk every few hours. We had it for months and nobody could fix it. Vector Dubai connected remotely, found the SIP session timer mismatch in about twenty minutes, and we haven't had a single drop since. Should have called them months earlier."
"We needed four new extensions added to our Panasonic KX-NS700 and the IVR reprogrammed with updated department routing. The original installer was unreachable. Vector Dubai had the PC programming software, came on-site, and completed the full reprogramme in one visit. Clean work and they tested every extension before leaving."
PABX Support Dubai — Frequently Asked Questions
My 3CX licence expired this morning and the phones stopped working. Can you fix this today?
Yes. WhatsApp us your renewal notice or the 3CX management console URL. We verify the licence details, confirm the renewal price, and once payment is confirmed we process the renewal through the 3CX partner portal. Most 3CX licence renewals are activated within 2–4 hours of payment. If the system entered the grace period shutdown, it restarts automatically once the licence is applied.
What's the difference between a 3CX subscription renewal and a licence upgrade?
A renewal keeps you on your current licence tier for another year — same simultaneous calls, same features. An upgrade moves you to a higher tier: more simultaneous calls, or from Standard to Pro or Enterprise. Both are annual. When we renew, we check whether your current tier still fits your actual call volume. If you're consistently hitting the ceiling, we'll tell you — and give you the cost difference before you decide.
Yeastar Linkus stopped working for all staff at the same time. What happened?
That's the signature of a Yeastar Linkus Cloud Service expiry. When the Linkus Cloud subscription ends, every user loses mobile and remote access simultaneously — which is why it looks like a system failure rather than a subscription issue. The core PBX keeps working for desk phones. We renew the Linkus Cloud subscription through the Yeastar partner portal and restore full access, usually within the same business day.
My NEC PABX has no support since NEC left the market. Can you still service it?
Yes. NEC exited the global hardware PBX business at the end of 2024 but the systems continue to work. Vector Dubai services the NEC SL2100, UNIVERGE SV9100, and older ASPIRE series. We have the programming tools, the experience, and access to remaining spare parts. We'll also give you an honest view of whether continued support makes sense long-term or whether migration planning is the better decision for your situation.
How much does PABX support and 3CX licence renewal cost in Dubai?
Remote support sessions start from AED 150 + VAT. On-site visits are quoted based on scope and location. 3CX licence renewal pricing depends on your current licence tier and simultaneous calls — small offices on 8SC start around AED 800 per year, enterprise licences go higher. We quote before confirming. No surprise invoices. Yeastar Linkus Cloud renewal is quoted per your subscription tier once we verify the system details.
Can you configure our Etisalat SIP trunk on a 3CX or Grandstream system?
Yes. We configure Etisalat (e&) and du SIP trunks on 3CX, Yeastar, Grandstream UCM, NEC SL2100, and Panasonic KX-NS. Etisalat and du both have specific settings that differ from generic SIP trunks — registration interval, codec preferences, and authentication type all matter. We've configured hundreds of these across Dubai offices. Most SIP trunk configurations are resolved in a single remote session.
What does IVR setup in Dubai cost and how long does it take?
IVR setup starts from AED 250 + VAT for a basic single-level menu on an existing system. Professional audio recording — a real voice, not text-to-speech — is available as an add-on. Complex multi-level IVR with time-based routing and department menus is quoted based on the number of levels and call flows required. Most IVR setups are completed in a single session. We test all routing live before handing over.
Can you support a Panasonic KX-NS700 that was installed by another company?
Yes. We support Panasonic KX-NS systems regardless of who installed them. We have PC Programming Software configured and engineers who know the platform. Adding extensions, adjusting IVR routing, configuring SIP trunks — all doable on existing Panasonic installations without needing to start from scratch.
My Grandstream UCM6510 extensions keep dropping. Is this a system fault?
Probably not a hardware fault. Extension dropping on Grandstream UCM is almost always a network issue — IP address conflict, PoE switch instability, or the PBX firewall settings blocking re-registration attempts after a timeout. We diagnose via the UCM web interface in a remote session. If it's happening after a network change — new router, new switch — that's usually the first place to look.
How quickly can you respond to a PABX support call in Dubai?

For 3CX licence expiry and Yeastar Linkus issues, we aim to have the fix in progress within the same session. Remote support can start the same day for most issues. On-site visits in Dubai are typically scheduled for the same day or next morning depending on location and call volume.
