Why Callifi

The phone company that picks up the phone

We're not a national call center. We're a family-run team based in NYC that serves the entire tri-state area โ€” setting up your system, showing up when it breaks, and answering when you call.

Local, on-site support

Our technicians dispatch from 16 East 40th Street in Midtown Manhattan. When something goes wrong, we're at your office โ€” not on a chatbot from another timezone. We cover all five boroughs, Westchester, Long Island, NJ, and CT.

We set up everything

You don't need an IT department. We configure your phone system, program your call routing, set up mobile apps, integrate your CRM, and train your team. You just pick up the phone and start working.

Responsive, human support

Call during business hours and a real person picks up โ€” someone in New York who knows your system. After hours, leave a message and we call back first thing. No ticket queues, no runaround.

Flexible terms

We offer flexible contract options including month-to-month plans. No multi-year lock-ins required. We earn your business by delivering โ€” not by trapping you in fine print.

One vendor for everything

Phone system, internet, cabling, elevator phones, repair โ€” one number to call, one team that knows your business, no finger-pointing between vendors.

Family-run, customer-first

Founded and run by Gill and Sass. When you call Callifi, you're treated like family โ€” because that's how we run our business.

Industries

Built for how your industry works

We configure your phone system around your business โ€” not the other way around.
