Managed IT and VoIP phone systems in Manhattan
TeleData Services provides managed IT services and business phone systems in Manhattan, with technicians on site every week. Manhattan work is office work: professional firms, practices and nonprofits in buildings where the riser, the landlord and the carrier each have a say. TDS plans around all three.
Phones, IT, security and cabling from one team
Hosted VoIP and Teams calling
Cloud phone system with desk phones, softphones and the mobile app, or calling inside Microsoft Teams on TDS numbers. Numbers ported on a scheduled date.
Guardian managed IT
24/7 remote helpdesk, monitoring, patching, backup and Microsoft 365 support, with cybersecurity layered on top.
Cameras and door access
Site survey, NDAA compliant cameras, local or cloud recording and remote viewing.
Cabling and Wi-Fi
Copper and fiber drops, racks, wireless and in-building cellular, labelled and tested.
How TDS works in Manhattan
Teams calling is the most common Manhattan request. Firms already live in Microsoft 365, and TDS TeamMate puts real phone numbers inside Teams without a separate phone system. Where desk phones are still wanted, Hosted VoIP runs alongside on the same numbers.

Asked in Manhattan
Can you work in an older building?
Yes. Older risers, missing pathways and crowded telecom closets are normal in Manhattan. The site survey finds the route before anything is quoted.
We are fully remote. Does TDS still help?
Yes. Hosted VoIP, Teams calling, AI voice agents and Guardian managed IT need no office at all.
Do you also work outside Manhattan?
Yes. TDS covers Long Island and all five boroughs daily, and installs and services customer sites in 42 states.
