SimiPlex began as a telecom-focused company serving New York businesses and grew naturally into managed IT — because the industry itself demanded it.
SimiPlex was founded by engineers and consultants who spent years in the trenches of enterprise telecom — designing PBX systems, deploying voice infrastructure, and managing complex carrier relationships for businesses across New York City.
We understood circuits, SIP trunks, and dial plans before most people had heard of the cloud. That depth of knowledge has never left us — it's still the foundation of everything we do.
What changed was the world around us. Voice moved to the internet. Networks became the phone system. Firewalls started carrying calls. The distinction between "telecom" and "IT" evaporated — and so we evolved.
SimiPlex started designing and deploying enterprise voice systems — Avaya, Nortel, and legacy PBX platforms — for NYC businesses across all five boroughs.
As VoIP, SIP, and unified communications platforms emerged, our clients needed network engineers alongside their phone techs. We built that capability in-house.
When NYC clients started asking us to manage firewalls, servers, and Microsoft 365 environments, we formalized our Managed Services practice.
Today, SimiPlex is a single-source technology partner for NYC businesses — covering communications, connectivity, IT, and physical infrastructure.
We recommend what's right for you, not what earns the biggest referral. We work across dozens of platforms and carriers.
When something breaks — phones, internet, or servers — you call one number. Us.
Our MSP team understands call flows, QoS, and SIP in ways that pure IT shops simply don't.
From 5-person Brooklyn offices to multi-site NYC enterprise deployments, we've done it all.
A discovery call costs you nothing. The right solution could save you everything.
