Free migration: Switching from NEC? We handle the port, dial plan rebuild, and rehome your phones at no charge. Talk to us

What's happening to NEC.

NEC announced in late 2024 that it is exiting the US small-and-mid-business phone market — globally NEC remains active and the larger SV9500 enterprise tier still ships internationally, but the US SMB channel is being wound down through 2025. The UNIVERGE SV-series and SL2100 product families that drove most US small-business installs are no longer the company's focus here.

The SL2100 is still technically being sold, but the US dealer count keeps dropping. Long-time NEC partners are either pivoting to cloud platforms (often as voip.army resellers) or being absorbed by larger MSPs that don't carry NEC at all. We hear the same story from customers every week: their familiar reseller stopped answering tickets, or got bought, or simply told them outright that they're not taking on new NEC work.

Support contracts you have today should be honored, and NEC isn't pulling the plug on existing systems — but the trajectory is clear. Replacement boards, PZ-DECT/IP DECT modules, and station cards are getting harder to source on short timelines. The right move is to plan the exit on your schedule, while the system still works and you have time to do it carefully.

NEC systems we migrate every week.

If you're running one of these, we have a playbook for your migration.

NEC UNIVERGE SV8100
The mid-market workhorse from the early-2010s era. Already past end-of-sale; supported only on contracted maintenance. The single most common NEC system we migrate.
NEC UNIVERGE SV9100
The SV8100 successor — same general capabilities, IP-first chassis. Still in active service across thousands of US small/mid businesses. Affected directly by the 2024 US SMB exit announcement.
NEC UNIVERGE SV9300 / SV9500
The enterprise UNIVERGE platforms — hospitals, universities, large corporate campuses. Global support continues, but US channel reductions hit these too.
NEC SL2100
The small-business platform (4–128 ports). Still nominally sold in the US, but with a shrinking dealer network. Common at small retail, dental and clinic offices.
NEC Aspire / Aspire S / Aspire IP
The previous-generation small-business platform from the 2000s. Long EOL. Still found at smaller offices that bought once and never touched it again.
NEC DT820 / ITZ-series IP phones
The IP/SIP-capable handsets on most SV9100/SV9300 deployments. Many can be reconfigured with generic SIP firmware for voip.army. DT400/DT430 digital sets are proprietary and get replaced.

How an NEC migration works.

Step-by-step. No surprises. Your existing NEC system stays operational the entire time.

01

We audit your current NEC setup

Send us a screenshot of PCPro or WebPro (the SV-series config tools). Tell us the chassis model (SV8100/SV9100/SV9300/SL2100), port count, trunk type, and which UNIVERGE features (InMail, MyCalls, UC suite) you actually use.

02

We mirror your dial plan and routing

Auto-attendant menus, ring groups, hunt groups, time-of-day routing, InMail or UM8000 voicemail trees, ACD queues — we rebuild it all in voip.army before the cutover.

03

We port your numbers

Every DID and trunk number currently on your NEC system ports to voip.army for free. The cutover is sub-5-second — no calls lost.

04

We rehome or replace your handsets

NEC DT820 and ITZ-series IP phones can usually be reconfigured for voip.army — we help with the SIP firmware swap and provisioning. DT400/DT430 digital sets and older Dterm phones won't survive the move; we quote Yealink or Grandstream replacements at cost. Many teams skip desk phones and use our mobile/desktop apps.

05

We turn off the NEC chassis

Decommission the SV8100, SV9100, SL2100, or larger chassis. Cancel the maintenance contract. Recycle the equipment.

An NEC customer, after.

★★★★★

"We've got eleven retail locations and a small corporate office, all on an SV9100. After NEC announced the US SMB exit our reseller stopped returning calls, and we knew we had to move. voip.army handled all twelve sites in five weeks — kept our ITZ phones at the stores with a reflash, rebuilt our store-routing tree exactly, and ported every line without a dropped call. We're saving about $1,200 a month versus the previous setup."

NEC migration FAQ.

The questions we get from NEC UNIVERGE customers considering the move. If yours isn't here, ask.

Talk to migration team
Many of them can. NEC DT820 and most ITZ-series IP phones (ITZ-8LDG, ITZ-12D, ITZ-24D, ITZ-32D) can be reconfigured for generic SIP firmware and registered to voip.army. We help with the firmware swap and provisioning. The DT400/DT430-series digital phones that shipped with most SV8100 and SV9100 systems are proprietary and only work behind an NEC KSU — those get replaced at cost with Yealink or Grandstream IP phones.
A small SL2100 site (under 20 users) takes 1–2 weeks end to end including porting. A mid-sized SV8100 or SV9100 deployment is 2–4 weeks. SV9300/SV9500 enterprise sites with multiple locations run 4–6 weeks. Your existing NEC system stays operational the entire time.
We rebuild your dial plan in voip.army from scratch — auto-attendant trees, hunt groups, ring groups, time-of-day routing, and your InMail or UM8000 voicemail boxes. We work from your PCPro / WebPro screens or a walkthrough with whoever maintains the system. Day-one feels identical to your callers and staff.
Historical voicemails on InMail or UM8000, and any NEC call recordings, stay on the NEC hardware — we don't migrate the audio. If specific messages matter, retrieve them before decommission. Going forward, voip.army delivers voicemail to email with audio attachments and AI transcripts, and records calls to encrypted storage (90 days standard, 7 years on Pro).
No. Keep your NEC support contract in place during the migration. With NEC winding down the US SMB channel, many customers find their partner is harder to reach anyway — but you still want fall-back coverage on the legacy system until voip.army has been live and stable for 2 weeks. Then cancel.
