Callifi is an Mitel acquired ShoreTel in 2017, then was itself acquired by RingCentral. The result: confusing support, rising costs, and disappearing parts. Callifi is the independent service provider that keeps your Mitel or ShoreTel system running — and migrates you when you're ready. On-site from Midtown Manhattan.
After the Mitel-ShoreTel merger and the RingCentral acquisition, support for on-premises Mitel and ShoreTel systems has gotten harder to find. Callifi is the independent service team NYC businesses call when their old vendor can't help anymore.
System down? We diagnose and repair MiVoice Business, MiVoice Connect (formerly ShoreTel Connect), ShoreTel Sky, and legacy ShoreTel systems on-site or remotely. Technicians dispatched same-day across NYC.
Proactive monitoring, firmware updates, and ongoing maintenance to keep your Mitel or ShoreTel system running. Firmware management, proactive monitoring, and same-day emergency support.
Replacement handsets, ShoreGear voice switches, expansion modules, and accessories. We stock ShoreTel 230/265/530/560/655 IP phones, Mitel 6900 series, and ShoreGear switch components.
Extension changes, auto-attendant setup, call routing, voicemail configuration, hunt groups, workgroups, auto-attendant, and Director/ECC programming for any Mitel or ShoreTel platform.
New phone drops, patch panel cleanup, MDF/IDF work, and structured cabling for Mitel and ShoreTel systems. ShoreGear switch rack installation, cabling, and phone deployment.
Ready to move off aging Mitel or ShoreTel hardware? We migrate your entire system to modern hosted PBX — same numbers, same extensions, modern features, lower cost.
From the original ShoreTel ShoreGear architecture to Mitel's MiVoice platforms, our technicians know the full product line inside and out.
Current Mitel platform
Mitel's flagship on-premises UC platform. We handle installation, programming, SIP trunk configuration, and ongoing maintenance. Full support for MiVoice Business Express and MiVoice Business servers.
Mitel-era platform
The rebranded ShoreTel Connect system under Mitel ownership. Same ShoreGear architecture with Mitel management overlay. We support all Connect ONSITE and Connect CLOUD deployments.
Legacy — we still support it
The original ShoreTel on-premises system before the Mitel rebrand. ShoreGear voice switches, ShoreTel Director, ECC contact center, and Workgroups. We repair, program, and maintain the full stack.
Legacy cloud — migration available
ShoreTel's original cloud offering, now largely superseded by Mitel's cloud products and RingCentral. If you're still on ShoreTel Sky, we can help you evaluate and migrate to a modern alternative.
Legacy cloud — migration available
Original ShoreTel systems with ShoreGear 24/24A, T1/T1A, and other voice switches. The distributed architecture that made ShoreTel famous. We still service, repair, and supply replacement switches.
Mitel cloud platform
On Mitel's cloud platform and finding support lacking since the RingCentral transition? We provide honest, vendor-neutral guidance on whether to stay or switch — and handle the migration if you decide to move.
Between the Mitel acquisition, the RingCentral deal, and the constant product rebranding, getting support for your on-premises Mitel or ShoreTel system has become a nightmare. Callifi cuts through the confusion.
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.
Our technicians are dispatched from 16 East 40th Street in Midtown. We service Manhattan, Brooklyn, Queens, Bronx, Westchester, and beyond.
ShoreTel became Mitel Connect, which became MiVoice Connect, which is now being pushed toward RingCentral. We know exactly which version you're running and what your actual options are — not what the sales team is pushing.
We have no relationship with RingCentral and no incentive to push you toward their platform. If your Mitel/ShoreTel system works and meets your needs, we'll keep it running. If it doesn't, we'll migrate you to whatever's actually best for your business.
We also service Avaya, NEC, Panasonic, and Nortel systems. Plus internet, cabling, elevator phones, and complete hosted PBX solutions.
Founded and run by Gill and Sasson Abada. When you call Callifi, you're treated like family — because that's how we run our business.
