Toshiba's Telecom Systems Division exited the US market in March 2017, ended software updates around 2018, and reached official end-of-life in 2020. Mitel was the named transition partner — but Mitel itself pivoted to cloud-only in 2023, narrowing the path further. If you're still running a Strata CIX, CTX, or DK system, the support pool is shrinking and replacement boards come from gray-market sellers only.
Toshiba America Information Systems shut down its Telecom Systems Division in March 2017, ending US sales of the Strata CIX and Strata CTX product families. Software development wound down through 2018 and official end-of-life landed in 2020. Mitel was announced as the migration partner at the time of exit — but Mitel has since pivoted to cloud-only and sold off its on-prem business, so that "transition path" effectively dissolved.
The Toshiba dealer network thinned out quickly after the exit. The shops still working on Strata gear are mostly long-time techs who learned the platform in the 2000s and are either retiring or actively migrating their own books of business to cloud VoIP. eManager and Network eManager (the Strata config tools) still run on aging Windows boxes, and finding a fresh install image is a scavenger hunt.
Replacement parts — DKSU cabinets, BIPU/RIPU IP cards, station and trunk modules, expansion shelves — are essentially gray market at this point. Used prices on common Strata CIX boards have climbed steadily as the pool shrinks. If your CIX or CTX is still healthy, that's the time to plan the exit — not after a power supply blows on a Friday afternoon with no spare in the state.
If you're running one of these, we have a playbook for your migration.
Step-by-step. No surprises. Your existing Toshiba system stays operational the entire time.
Tell us the model (Strata CIX40/100/200/670, CTX, or DK), station count, trunk type (analog/T1/PRI), and what features you use. A screenshot of eManager or Network eManager and a photo of the cabinet is enough.
Auto-attendant menus, hunt groups, ring groups, intercom paths, time-of-day routing, and Stratagy ES voicemail trees — we rebuild it all in voip.army before the cutover.
Every DID and trunk number currently on your Strata system ports to voip.army for free. The cutover is sub-5-second — no calls lost.
Toshiba IP5022/IP5122/IP5132 SIP phones can sometimes be reflashed for voip.army — we'll attempt it where firmware cooperates. DKT/IPT digital sets won't survive the move and get swapped for Yealink or Grandstream IP phones at cost. Many teams skip desk phones entirely and use our mobile and desktop apps.
Decommission the CIX, CTX, or DK cabinet. Stop paying your local break-fix tech. Recycle the equipment.
"Our cabinet shop ran a Strata CIX100 for fifteen years and it was great until it wasn't. After Toshiba left the US we limped along with one local tech, and when he retired we had no plan. voip.army rebuilt our auto-attendant exactly, ported our two PRIs without a hiccup, and shipped Yealinks to every desk. We're saving about $640 a month versus the old maintenance contract plus carrier bill."
