Upgrade with confidence through The Green Migration: Upgrade without disruption. Preserve your investment, reduce waste, and unlock new capabilities.
Why Now Is the Time to Upgrade from NEC
Legacy NEC systems have supported businesses for years, but with product lines discontinued and support ending, organizations are beginning to face:
- Aging hardware and declining reliability
- Limited availability of replacement parts
- Rising maintenance and service costs
- Security vulnerabilities with no new patches
- Increased risk of outages or downtime
- No clear upgrade, growth, or expansion path
The good news:
CBSi and E-MetroTel can help you migrate and modernize without disruption, preserving what still works while upgrading strategically to a secure, future-ready platform

XSTIM®: The E-MetroTel Advantage
E-MetroTel’s patented XSTIM® technology allows many NEC digital and IP phones to work natively on the UCX platform without firmware updates, device reprogramming, or workflow changes.
By shifting the “intelligence” of the system from the handset to the UCX platform, XSTIM® enables UCX to communicate with NEC and other vendor devices as if it were their original controller, ensuring full feature support while keeping devices stable, familiar, and fully functional.
Benefits of XSTIM®
- Preserve NEC button layouts and workflows
- Maintain user settings and configurations
- No firmware updates or device reprogramming
- Support for digital, IP, SIP, and H.323 devices across vendors
- Zero disruption to daily operations
- Lower environmental impact through The Green Migration
NEC Device Compatibility
Thanks to XSTIM® and UCX’s multi-protocol support, E-MetroTel provides extensive compatibility with legacy NEC digital and IP phones, allowing you to preserve your current devices while modernizing your system.
