Deep legacy
Running KX-T7736, KX-T7735, or other legacy Panasonic digital phones? We can still service these systems and help you plan a transition when the hardware becomes unreliable.
Panasonic's U.S. business phone division has been shrinking, and many authorized dealers have left the market. Callifi is the independent service provider that's still here.
Call us any time. During business hours, a real person picks up — someone in New York who knows your system. After hours, leave a message and we'll call you back first thing. No ticket queues, no runaround.

From KX-TA624 analog systems to KX-NS700 IP platforms — we've installed, repaired, and programmed every generation of Panasonic business phone system.
Panasonic has been reducing its North American business phone presence. We'll tell you honestly whether your system has years of life left or whether it's time to plan a migration — and we'll handle whichever path you choose.
