Best Alternative to NEC SL2100 and SV9100 — Migrate to IZT Cloud Voice

Why NEC Partners Are Moving On

NEC announced its exit from on-premises UC. These are the issues driving the transition.

NEC Is Exiting the UC Market

In April 2024, NEC announced its intention to exit the on-premises UC market. Resellers who built their business on NEC SL2100 and SV9100 platforms now face a critical portfolio gap.

Obsolete Architecture

NEC uses proprietary, vendor-locked software with low interoperability. No open APIs, limited CRM integrations, and no path to modern cloud communications.

Complex Hardware & Licensing

Complex PBX with 16+ independent blades and cards. 79 separate licenses for 79 services. Basic features like SIP extensions and voicemail-to-email require extra license purchases.

No Modern UC Clients

Three different softphone systems (ST500, SP310, InUC) with inconsistent UI across platforms. No unified experience. ST500 requires additional SBC devices for remote access.

Limited Integration & Ecosystem

No third-party IP phone auto-provisioning. No open APIs. CRM integration limited to Outlook, Goldmine, and ACT! only. No Microsoft Teams integration.

Insufficient Partner Support

Seldom product updates. Late support response that mostly depends on distributors. No vendor-provided direct training or webinars. Limited marketing support.

Why Partners Choose IZT Cloud

A modern, managed UCaaS platform purpose-built for the channel — with NEC IP phone compatibility built in.

Cloud, On-Premise, or Hybrid

Deploy how your customers need — fully managed cloud UCaaS, on-premise hardware appliances (S412, P550, P560), or software edition on AWS/VMware/Hyper-V. All share the same UI.

NEC IP Phone Compatibility

Auto-provisioning supports 300+ models from 10+ brands, including certified NEC IP phones (DT800, DT900 Series). Customers keep their existing NEC phones after migration.

One Unified Client Experience

A single Cloud Voice client across iOS, Android, Windows, Mac, Web, and Chrome Extension. Consistent UI, full feature parity, no extra per-user licenses.

Simple 3-Plan Licensing

Three subscription plans replace 79 separate NEC licenses. All basic features included with hardware at no extra cost. Easy bundle sales with recurring revenue.

Full Integration Ecosystem

Open APIs, Salesforce, HubSpot, Zoho, Zendesk, Microsoft Teams native integration, Microsoft Active Directory, and 300+ auto-provisioned phone models.

Managed Partner Portal

Remote system management, SIP trunking provisioning, 10DLC compliance, E911 provisioning, license management, and marketing resources — all from one portal.

Contact Center Included

Inbound and outbound call center, queue management, wallboards, analytics, and omnichannel messaging included in every plan. NEC charges extra for Contact Center licenses.

Quarterly Product Updates

Focused innovation with quarterly updates. NEC upgrades had slowed or stopped entirely before their market exit announcement.

Seamless Migration from NEC

IZT Cloud makes the transition from NEC as smooth as possible.

Keep Existing Infrastructure

Support for landlines (ISDN/PSTN) and SIP trunks, plus multiple telephony interfaces (FXS, FXO, GSM, PRI). Your analog infrastructure stays.

NEC IP Phone Compatibility

Auto-provisioning for NEC DT800 and DT900 Series IP phones plus 300+ models from 10+ brands. Keep using current NEC phones.

One System for All

On-premises, cloud, or software — IZT Cloud covers all bases. All editions share the same UI and design, making cloud migration easy when ready.

Rapid Partner Onboarding

Certification-based training, quick sales playbooks, comprehensive demo kits (NFR and free trial), and 1:1 webinar training available.
