End-of-sale campus switching
ERS and Legacy Avaya
ERS gear is still carrying traffic in a lot of buildings, and a failed unit should not force an unplanned refresh.
We source spares, hold them against your model list, and swap failures on site.
Hardware shipped worldwide and crews dispatched from our Las Vegas warehouse.

Questions we get
ERS and Legacy Avaya, answered straight
How long can we keep running ERS?
As long as spares are available and the platform does the job. We will tell you honestly when a model is genuinely getting hard to find.
Can you plan the eventual migration?
Yes. Design, elevations, and a priced bill of materials, then a phased cutover when the budget exists.
