Avaya Repair First. Replacement Only When It's Time. Brooklyn-Based, All 5 Boroughs.

If your Avaya system is failing, refusing to find replacement parts, or your maintenance bills are climbing, you have options. We service and repair Avaya systems across NYC, and we replace them when the time is right. Honest answer either way.

The Avaya situation in NYC, 2026

Avaya filed for Chapter 11 bankruptcy in 2023, restructured, and emerged with a focus on cloud and software. The hardware-platform side that powers most legacy Avaya systems in NYC small offices, Partner ACS, IP Office, Definity, Magix, is no longer in active development. Replacement boards and proprietary phones are getting harder to source. Maintenance contracts are getting more expensive. And the underlying carrier infrastructure these systems depend on, especially analog and PRI lines from Verizon and the legacy carriers, is being phased out as those carriers move to fiber and IP delivery.

The result: every NYC office still running on Avaya hardware is approaching a decision. Repair while it still makes sense, or replace before failure forces an emergency switch.

We work with both. Our techs are familiar with the major Avaya platforms, we still repair them daily for NYC businesses that aren't ready to switch. We also do clean migrations to modern cloud phone systems when the math finally tips. The honest answer isn't always "replace it", sometimes another year of repair is the right call. We'll tell you which fits your situation.

Avaya systems we work with

The Avaya platforms still common in NYC small business offices, all of which we service:

• Avaya Partner ACS (R1 through R8), small-office hybrid digital/analog system, widely deployed across NYC dental practices, small accounting firms, and other 4-to-20 line offices since the late 1990s.
• Avaya IP Office (IP500, IP500 v2), mid-size hybrid IP platform, replaced the Partner line for slightly larger offices. Many still in service.
• Avaya Definity, older enterprise system you'll still find in older NYC office buildings. Parts increasingly scarce.
• Avaya Magix, small business system that came after Partner. Still operational in some long-tenured offices.
• Avaya Merlin, older platform we occasionally see, mostly in offices that haven't touched their phone system in 20+ years.
• Avaya Aura, newer enterprise IP platform. Sometimes encountered in larger NYC offices.

If your Avaya system isn't on this list, ask us anyway. We've worked with most of what's still running in NYC.

Repair or replace: how to think about the decision

Replacement isn't always the right answer. Some NYC offices get another 2 to 4 years out of a properly maintained Avaya system, and the cost of replacement doesn't pencil. Here's how we frame the decision when we walk into your office:

Repair makes sense when

• Your system is running stably with only occasional issues we can fix on-site
• Replacement parts are still available through our supply channels at reasonable cost
• Your call volume and feature needs haven't outgrown what the system can deliver
• Your carrier lines (analog, PRI, T1) are still being supported by your carrier and aren't scheduled for retirement
• You don't need the modern features cloud phone systems provide, mobile apps, queue callback, multi-level IVR routing, hot desking, integrations with software your team uses

Replacement makes sense when

• Parts for your system are no longer available, or the cost has become prohibitive
• Your maintenance contract is consuming more than 6 months of equivalent cloud-system cost annually
• Your carrier has notified you of analog or PRI line retirement at your address
• You need features the old system can't deliver, mobile softphone, modern auto-attendant, voicemail-to-email (add-on), integration with your CRM or scheduling software
• You're hiring, adding locations, or otherwise outgrowing the system's design
• You've had multiple service calls in the last 12 months that resolved but indicate the system is failing

The middle path: stage the migration

For some offices, we recommend a staged plan, keep the Avaya system operational for another 6 to 12 months while we build out the new cloud infrastructure in parallel. When the new system is ready and tested, we execute the cutover during a planned window. This lets you spread cost and risk across a longer timeline rather than doing everything at once.

What an Avaya-to-cloud migration looks like

Once you've decided to replace, here's what the actual project looks like for a typical NYC office (3 to 15 users, single location):

Week 1, Discovery and planning

We come on-site, inventory your existing Avaya system, document your call flows (auto-attendant menus, hunt groups, ring groups, voicemail boxes, extensions), confirm your carrier setup, and identify any custom programming. You get a fixed quote and a written deployment plan that maps your current setup to the new cloud system feature by feature.

Week 2, Parallel build

We provision the new cloud PBX with all your extensions, IVR menus, and hunt groups configured to match your existing setup. New IP phones are programmed and tested at our location. Your Avaya system keeps running normally, nothing changes for callers or staff during this phase.

Week 3, Number porting and cutover

Number porting takes 7 business days on the carrier side. We schedule the actual port and cutover for a weekday morning so any issues can be addressed during business hours. The cutover window is typically under 15 minutes of perceptible activity. Your Avaya system stays online as a fallback until the new system is verified handling every call type correctly.

Week 4, On-site training and tuning

We come back to your office, train each staff member on the new system (especially the mobile app and any features they didn't have before), tune the IVR menu based on real-world call patterns, and document the new setup for your records. You can reach a real engineer, not a tier-one queue, for any questions after.

What you get on the new system

The cloud phone system we deploy includes the features that the older Avaya platforms can't easily provide. None of these are add-ons, they're standard with our Business plan at $29.99 per user per month.

Pricing

We publish our pricing rather than hide it behind a quote form. For most NYC small offices migrating off Avaya:

• Business plan: $29.99 per user per month. Includes a new Yealink IP desk phone provisioned for your setup, full PBX features, mobile and desktop softphone, and unlimited US and Canada calling. This is the right fit for most NYC dental practices, accounting firms, real estate offices, restaurants, and small professional services, typically 3 to 15 users.
• Standard plan: $19.99 per line per month. Fits very small offices with one or two lines and basic feature needs. Avaya replacement customers usually fit the Business tier instead.
• Enterprise: custom pricing. For multi-location operations, call-center setups, or anything with non-standard requirements (50+ users, complex compliance, etc.).

The total cost includes the new phones (provisioned and configured), number porting, on-site install and training, and the first month of service. No surprise fees and no contracts.

Why a Brooklyn-based provider for Avaya migration

National VoIP providers will sell you a cloud phone system. They will not show up at your office in Midwood when the front desk phone is dead and patients are calling. They will not climb your ceiling tiles to trace the line that the old Avaya tech ran in 2008. They will not know which carrier serves your building and which one doesn't.

We do all of that, because we're physically based in Brooklyn and our techs are NYC residents. No subcontractors, no offshore call center, no tier-one runaround. When your phone system has a problem, you call us. The same person you talked to during the install is the person you reach for support.

That matters during an Avaya migration specifically, because old systems have legacy cabling and odd custom programming that nobody at a national call center has any context for. Local expertise saves days when something needs to be diagnosed in person.
