NEC's SL systems have been well received for several years now. The
SL2100 has been a cost effective solution for many small businesses,
including the hospitality business.
NEC SL1100 PBX Guides
The NEC SL1100 is a hybrid IP PBX that NEC for small businesses, supporting up to roughly 40 extensions on a single server with expansion potential toward 100 users across multiple offices. It offers a mix of digital, analog, and IP extensions, plus PSTN, ISDN, and SIP trunking, along with built-in automated attendant, voicemail with email notification, ring groups, music on hold, door phone/door striker interfaces, and Mobile Extension so a cell phone can act as an office extension. Critically, it has reached end-of-life: NEC announced this on March 31, 2019, meaning no new user licenses, no software updates, and no manufacturer technical support for over seven years now. NEC's successor is the SL2100, which can reuse existing SL1100 digital desk phones and door-box units, making it the natural upgrade path for businesses still running the older system.

NEC SL2100 PBX Guides
The NEC SL2100 is the hybrid IP PBX NEC launched as the successor to the
SL1100, delivering a more scalable, feature-rich platform aimed at small
and mid-sized businesses. It ships with a built-in 4-port InMail voicemail,
auto-attendant, music on hold, door-phone connectivity, and 8 VoIP channels
included at no extra license cost, so a basic system works out of the box.
It supports a hybrid mix of digital, analog, and self-labeling IP phones
(including color-screen VoIP sets and DECT cordless) and is expandable. The
mobility feature, with Mobile Extension, lets a smartphone act as an office
extension; plus, it offers softphone apps, remote/home-office support,
audio and video conferencing, call recording, and browser-based management.
However, the platform is now in a winding-down phase: NEC stopped
taking new system orders on December 31, 2024, and ended all manufacturer
technical support and software maintenance on March 31, 2026, with the
SL2100 manufacturing plant permanently closed and remaining hardware
limited to reseller inventory and the secondary market. Businesses still
running the SL2100 will increasingly need third-party support as NEC exits
the on-premise market.
