Family-run. NYC-based. Obsessively hands-on.

Callifi is a business phone system company founded and run by Gill and Sass out of Midtown Manhattan. We've been building, repairing, and supporting phone systems for NYC businesses since 2016.

Our Story

We grew up in telecom

Callifi was founded by Gill and Sass โ€” two brothers who grew up in the telecommunications business. Our family has been working with business phone systems for decades, from the analog PBX era through the digital transition and into today's cloud-hosted VoIP world. We've seen every generation of phone system technology, and we've installed, repaired, and replaced all of them.

We started Callifi because we saw how badly most businesses were being served by their phone providers. The big national companies treat you like a ticket number. The old-school PBX dealers charge you for hardware you don't need. And the DIY cloud platforms leave you configuring your own call flows at 10pm on a Sunday. We thought there should be a company that actually knows phone systems, shows up at your office, and makes it work โ€” then sticks around to keep it working.

That's Callifi. We're not a call center. We're not a reseller. We're the people who answer the phone when you call, show up at your office when something breaks, and know your system because we built it.

How We Work

Partners, not salesmen

We fix before we replace

If your current phone system can be repaired or upgraded, we'll tell you. We don't push new hardware on businesses with perfectly functional equipment. We only recommend a replacement when repair isn't cost-effective.

We show up in person

We're based at 16 East 40th Street in Midtown Manhattan. When you need on-site support, we come to you โ€” same day in most cases. No ticket queues, no "we'll escalate this." A real technician at your office.

We're brand-independent

We're not tied to any one manufacturer. We recommend and service Cisco, Poly, Yealink, Grandstream, snom, Konftel, and others. We also service legacy systems โ€” Avaya, NEC, Nortel, Panasonic, Mitel, and Toshiba.

We're honest about costs

We clearly communicate every cost before you commit. No surprise charges, no hidden fees, no "that's extra." Month-to-month options available โ€” we earn your business every month, not through a contract lock-in.
