Bespoke, automatic follow-up tests.
Proactively manage your telecoms infrastructure.
Follow-up alerts are activated by users who need a way to check a number that had a fail state result when tested to identify if the fail is part of a persistent problem, or a once-off occurrence. They are used when an organization needs to automatically trigger a follow-up test not just from “busy” fail states, but for all fail states.
