From Midtown Manhattan to Downtown Brooklyn, SimiPlex is the NYC telecom and MSP partner businesses trust. One integrated approach, one vendor, zero finger-pointing.
Cloud and on-premise phone systems from Avaya, RingCentral, Microsoft Teams, Nextiva, Dialpad and more — designed for how your NYC team works.
Business internet, dedicated fiber, 5G, MPLS, and SD-WAN solutions sourced from top carriers and optimized for reliability across New York.
Proactive monitoring, firewall management, server administration, Microsoft 365 support, and help desk — NYC IT support that just works.
Structured cabling, IP security cameras, door access control, emergency paging — installed cleanly and built to NYC code.
New York businesses deserve better than juggling six vendors. One call to SimiPlex covers it all.
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.
From traditional PBX to fully cloud-based UCaaS platforms, SimiPlex designs, deploys, and supports the right communication solution for your New York business.
Not every NYC business needs the same phone system. Some need on-premise control; others need the flexibility of cloud. Many need a hybrid approach. SimiPlex evaluates your environment, call volume, integration requirements, and budget — then recommends the platform that truly fits.
Our telecom engineers have decades of combined experience across legacy Avaya PBX systems, modern UCaaS platforms, and everything in between. We don't just sell licenses — we architect solutions.
RingCentral, Nextiva, Dialpad, 8×8, and Vonage give you enterprise features without on-premise hardware. Ideal for distributed NYC teams with predictable monthly costs.
Avaya and Cisco platforms are the gold standard for organizations requiring strict call control, compliance, or complex routing logic across multiple NYC locations.
Already in Microsoft 365? We configure Teams as your full business phone system with Direct Routing or Calling Plans — communicate in one place.
We offer a free telecom assessment and recommendation — no commitment required.
Fast, reliable, and cost-effective internet and network services — sourced from the best carriers and managed by SimiPlex on your behalf across NYC and the tri-state area.
Whether you're running cloud phones, remote workers, or mission-critical applications, your internet connection needs to be fast, redundant, and priced right. SimiPlex acts as your telecom broker — shopping multiple carriers to find the best fit for your NYC location.
Dedicated and shared fiber internet from leading ISPs. We negotiate rates, manage provisioning, and handle carrier escalations so you don't spend hours on hold.
Where fiber isn't available or a backup is needed, 5G fixed wireless delivers enterprise-grade speeds with fast deployment across NYC's five boroughs.
Intelligently route traffic across multiple connections — balancing performance, reliability, and cost. Perfect for multi-location NYC businesses.
Secure, private WAN connectivity between offices and data centers for NYC organizations with strict compliance, latency, or security requirements.
Replace aging PRI and analog phone lines with SIP trunks — reducing costs significantly while adding flexibility, scalability, and failover capability.
We design dual-carrier strategies that keep your New York business connected even when a provider has an outage.
SimiPlex is not tied to any single carrier. We work with AT&T, Verizon, Comcast Business, Spectrum, Lumen, Windstream, and dozens of regional providers — comparing options objectively to find the best combination of speed, reliability, and price for your NYC business.
We also become your ongoing carrier liaison. When there's an outage, a billing dispute, or a needed upgrade, you contact us — not a carrier call center.
A quick audit from SimiPlex often uncovers significant savings. Let's take a look.
Proactive, responsive, and experienced managed IT services that keep your New York business running — without the cost of a full-time internal IT department.
Most MSPs handle your servers and software. SimiPlex handles all of that — plus the network layer, plus the phones, plus the carrier connections underneath it all. That holistic view means faster troubleshooting and fewer vendor finger-pointing incidents.
Whether you're a small Brooklyn business needing basic support or a mid-market Manhattan organization requiring mature security and compliance practices, we build a plan to fit.
Enterprise-grade firewalls from Fortinet, Cisco Meraki, SonicWall, and Palo Alto — including rule management, firmware updates, and threat response.
Physical and virtual server management across Windows Server and Linux. Active Directory, DNS, DHCP, file shares — all monitored proactively.
Full M365 administration including user onboarding, Exchange Online, SharePoint, Teams, Intune device management, and licensing optimization.
EDR, email security, multi-factor authentication, security awareness training, and vulnerability assessments — layered protection for NYC businesses.
We implement and monitor backup solutions for servers, workstations, and cloud data — and test recovery to ensure your data is there when you need it.
Responsive, knowledgeable support technicians for day-to-day IT issues — remote and on-site across the NYC metro area.
We'll identify gaps, risks, and opportunities — at no charge.
Clean, code-compliant installations of the physical systems that keep your New York business connected, safe, and informed.
SimiPlex's low voltage team has installed infrastructure for offices, retail spaces, schools, medical facilities, and warehouses across New York City and the tri-state area. Every installation is clean, labeled, and documented.
Cat5e, Cat6, and Cat6A data cabling, fiber optic runs, and cable management. Certified installations with full test documentation — built to last.
HD and 4K IP camera systems with local NVR recording and cloud options. Indoor, outdoor, PTZ, and license plate cameras from Axis, Hikvision, Verkada, and more.
Key fob, card reader, and mobile-based access control systems. Track who enters your NYC facility — with centralized management and real-time alerts.
IP-based paging systems for overhead announcements, emergency alerts, and zone-based communication — integrated with your phone system where needed.
Enterprise Wi-Fi design and installation using Cisco Meraki, Ubiquiti, and Aruba — with proper site surveys, density planning, and seamless roaming.
Telecom room design — structured patch panels, cable management, rack mounting, and labeling for a clean, maintainable infrastructure.
Most technology problems start at the physical layer — a bad cable, a crowded patch panel, a camera in the wrong location. By handling both the physical infrastructure and the technology on top of it, SimiPlex eliminates the blame game between contractors and IT vendors.
Our low voltage team coordinates directly with our MSP and telecom engineers, ensuring that what gets installed in the wall actually works with the systems running in the cloud.
