Overview

The SBC SWe performance metrics for simultaneous sessions under a full-fledged Denial of Service (DoS) attack for various call scenarios are summarized in the "Benchmarking Results" section

...

of the following pages. Note that these numbers apply to our recommended CPU and memory configurations, and the results may vary depending on the actual CPUs used. Exceeding these simultaneous sessions metrics in conjunction with a Denial of Service attack may result in poor call performance, including longer call setup times and/or poor voice quality. It is therefore recommended to maintain call rates within the performance limits that are benchmarked below.
