What We Fix

Common phone system problems we solve daily

If it's broken, making weird noises, dropping calls, or just stopped working entirely โ€” we've seen it before and we can fix it.

Common

Dead phones / no dial tone

Phones aren't ringing, no dial tone, display is blank. Could be a power supply issue, a dead line card, a wiring fault, or a trunk problem. We diagnose and fix it on-site.

Dropped calls & poor audio

Calls cutting out, one-way audio, static, echo, or choppy voice. Often a network issue, SIP trunk misconfiguration, or faulty cabling. We identify the root cause โ€” not just the symptom.

Voicemail not working

Messages not recording, voicemail-to-email broken, greetings not playing. We fix CallPilot, Partner Mail, IP Office voicemail, InMail, and cloud voicemail systems.

Auto-attendant & routing issues

Callers going to the wrong extension, auto-attendant playing the wrong greeting, night mode stuck on. We reprogram your call flow and test it end-to-end.

System won't boot / power failure

PBX controller down, power supply failed, system stuck in reboot loop. We carry common replacement parts and can often get your system back up the same visit.

Can't add or move extensions

Need to add a phone, move a desk, or reassign an extension? We handle programming changes, new cable runs, and phone provisioning โ€” usually in one visit.

Lost your POTS lines? Your phone system doesn't have to die.

Carriers are retiring copper lines across NYC. If your analog trunks are failing and the phone company won't fix them, we install SIP trunks on your existing PBX โ€” same phones, same numbers, same system. No rip-and-replace.

Why Callifi

Why NYC businesses call us when their phones go down

Same-day on-site service

We dispatch technicians from 16 East 40th Street in Midtown Manhattan. Call in the morning, we're at your office in the afternoon. Not next week โ€” today.

Every brand, every era

Avaya Partner from 2004? NEC DSX from 2008? Brand new Yealink VoIP setup? We've worked on all of them and we carry common parts for legacy systems that are hard to source.

We fix the problem, not the symptom

When your phones drop calls, most techs swap a handset and leave. We trace the issue back to the root cause โ€” bad cable run, failing power supply, misconfigured SIP trunk โ€” so it doesn't happen again.

Honest assessment

If your system can be repaired cost-effectively, we'll fix it. If it's on its last legs and repair costs are going to keep climbing, we'll tell you that too โ€” and offer a clear migration path to modern hosted PBX.

Not just repair โ€” everything

We also do cabling, internet, elevator phones, and full phone system installations. One call to Callifi handles everything communication-related in your office.

Tri-state coverage

We service all five NYC boroughs, Westchester, Long Island, Northern New Jersey, Connecticut, and the Hudson Valley. Local numbers in each region for fastest response.

FAQ

Common questions about phone system repair

How fast can you get to my office?
For same-day emergency service in NYC, we typically dispatch a technician within 2-4 hours of your call. Our team works out of Midtown Manhattan and covers all five boroughs. For Westchester, Long Island, New Jersey, Connecticut, and Hudson Valley, same-day service is often available depending on location and time of call. Call your regional number for the fastest response.
Do you repair old phone systems that are no longer supported?
Yes โ€” this is one of our specialties. We repair Avaya Partner ACS, Avaya Definity, NEC DSX, Norstar MICS/CICS, Nortel BCM, Panasonic KX-TDE, Toshiba DK, and other legacy systems that their manufacturers have discontinued. We stock common parts for these systems including handsets, trunk cards, power supplies, voicemail cards, and expansion modules. If your system is repairable, we'll fix it. If it's beyond practical repair, we'll tell you honestly and offer migration options.
How much does phone system repair cost?
For pay-as-you-go service, we charge an hourly labor rate plus any required parts. For businesses that want ongoing coverage, our maintenance contracts include unlimited repairs, parts, and technical support for a flat monthly fee. We provide free assessments to diagnose the problem before quoting any work โ€” you'll know exactly what's wrong and what it costs before we start. Call (212) 423-1234 for a free assessment.
Should I repair my phone system or replace it?
It depends on the system's age, the nature of the problem, and the cost of parts. If you're facing a one-time issue on an otherwise healthy system, repair almost always makes sense. But if you're seeing recurring failures, rising repair costs, or difficulty finding replacement parts, migration to a modern hosted VoIP system is often cheaper in the long run. We'll give you an honest comparison of repair vs. replace costs so you can make an informed decision โ€” we profit from both, so we have no incentive to push you either way.
Can you repair VoIP and cloud phone systems too?
Yes. We troubleshoot and repair hosted VoIP, SIP trunk, and cloud-based phone systems in addition to legacy digital and analog PBX systems. Common VoIP issues we fix include call quality problems (choppy audio, one-way audio, echo), registration failures, SIP trunk outages, network configuration issues, and QoS misconfigurations. If the problem is on your carrier's side, we identify it and escalate with them on your behalf.
Do you service phone systems outside NYC?
Yes. We provide on-site phone system repair throughout the tri-state area: all five NYC boroughs, Westchester County (White Plains, Yonkers, New Rochelle), Long Island (Nassau and Suffolk counties), Northern New Jersey, Connecticut (Fairfield County), and the Hudson Valley. We have local phone numbers in each region โ€” call the number for your area for fastest dispatch.
