This object reports the number of calls successfully routed through the CUSP system during the most recent one-second interval. An admin uses this near-instantaneous figure to observe live call routing activity, useful for confirming the proxy is actively processing traffic during a suspected outage investigation. If a user reports call failures but cuspCallsRoutedOneSec shows healthy ongoing routing activity, the admin would suspect the issue is isolated to that user's specific call path rather than a system-wide routing failure.
