Phones, IT and security from one Hauppauge team since 2018
TeleData Services (TDS) is a Long Island technology company. We install and run business phone systems, managed IT, cybersecurity, cameras and cabling for 1,700+ customers across Long Island, New York City and 42 states. One contract, one number to call, and a person who answers it.
From a living room to 42 states
The milestones that made TDS what it is today.
Where TeleData began
TeleData Services started in a living room as a reseller in the technology industry, learning the business one customer at a time and building client relationships we still have today. As we grew, we made a deliberate decision to become a direct provider, which gave us control over service delivery and the freedom to build the right solution for each business instead of selling what a vendor had on the shelf.

Founded, Long Island
White-label services
TDS added white-label phone and network services, building the technical depth behind the solutions we now deliver directly.
October 2019
White-label expansion
TDS Hosted VoIP
TDS became its own VoIP provider. Number porting, phone programming and support moved in house, and TDS Hosted VoIP became the core of the business.
September 2021
VoIP provider launch
Managed IT and cybersecurity
TDS Guardian managed IT and TDS Cybersecurity joined the phones, so one agreement could cover the helpdesk, the network and the security.

Beyond telecom
The phone that answers itself
TDS AI Voice Agents answer every call 24/7 in natural language, book and confirm appointments, take messages and hand off to your staff with the caller's details already captured. Alongside them, TDS TeamMate puts your TDS numbers inside Microsoft Teams and TDS Document Management turns filing cabinets into one searchable system. Eight years in, the plan is the one we started with: answer the phone, fix it right, and earn the next call.

TDS AI Voice Agents, plus TeamMate and Document Management
Treat every customer the way we would want to be treated
That one belief drives the rest: lead with integrity, deliver with care, and build relationships that feel more like family than business. In practice it looks like this.
A person answers
Sales and support are answered from the Hauppauge office by the same team that installs and maintains your systems. No ticket portal maze.
Everything in writing
Scope, price and response times go in the agreement before the work starts. If something changes, the change order comes first.
One team for the whole stack
Phones, network, cabling, cameras and the helpdesk from one company, so there is never a vendor pointing at another vendor.
Straight advice
When a repair stops making sense or a cheaper option fits better, we say so. Customers stay because the advice holds up.
The people who pick up when you call
Sales, support, engineering and billing, all in Hauppauge.
