AT&T Synapse has been discontinued — no longer manufactured or actively supported

The AT&T Synapse small business phone system (SB67030, SB67025, SB67080, SB67040 series) has been discontinued. New units and replacement parts are no longer being manufactured. If your Synapse system is aging or failing, Phonewire can help you migrate to a fully supported modern platform and preserve your existing phone numbers.

AT&T Synapse — Discontinued System

Time to Upgrade from AT&T Synapse? Here’s Your Clearest Path Forward.

The AT&T Synapse was one of the most popular small business phone systems of its era — simple to install, reliable on traditional landlines, and expandable without licensing fees. Its discontinuation leaves a large installed base of businesses now facing aging hardware and no manufacturer support path. Phonewire has helped many of these businesses migrate cleanly to modern VoIP systems — keeping their numbers, preserving their features, and gaining capabilities Synapse never had.

What Synapse Users Valued — And What Replaces It

No internet required. Synapse ran on traditional phone lines — a genuine advantage for businesses worried about internet reliability. Phonewire’s hybrid on-premises system can include built-in cellular failover: if your internet goes down, calls automatically continue on a 4G LTE backup connection in under one second.

No per-user licensing. Synapse’s model — buy phones, expand as needed, no recurring license fees — matched how small businesses think about infrastructure. Phonewire’s hybrid uses a flat $699/year license for up to 20 users. The same philosophy, with modern SIP trunking instead of analog lines.

Features you didn’t have. Synapse was limited to basic call handling. Your replacement system includes voicemail to email, a mobile app that turns your smartphone into an office extension, auto-attendant, call recording, CRM integration, and Microsoft 365 connectivity — all included.
