What Makes Us Different
Authorized — Not Just a Reseller
We hold authorized distributor status for Grandstream, Yeastar, Yealink and NEC in the UAE. This means genuine warranty, official firmware, and direct manufacturer support. Not grey market, not parallel import.
Stock in Dubai — No Waiting
Core models are stocked in our Dubai warehouse. Small office systems can be installed the same week. No waiting for overseas shipment. No project delays because of supply chain gaps.
Installation Is the Default
We supply and install every system we sell. Configuration — extensions, IVR, ring groups, SIP trunks, Wave app — is included in every project. You don't manage the installation. We do.
WhatsApp-First Support
Our engineers are reachable on WhatsApp during UAE business hours. Remote diagnosis first — most issues resolved without a site visit. On-site same day in Dubai when hardware fault is confirmed.
Etisalat & du SIP Trunk Experience
We have configured VoIP phone systems and SIP trunks for Etisalat Business and du Business on every major PABX platform. TRA-compliant VoIP setup is standard on every installation — no guesswork on UAE regulatory compliance.
Serving Dubai and All 7 Emirates
Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah, Umm Al Quwain — plus free zones including DMCC, DIFC, JLT, and DAFZA. Same pricing, same service level, across the UAE.
We Serve All Seven Emirates
