The SBC SLB performance metrics for simultaneous sessions for various call scenarios are summarized in the "Benchmarking Results" section of this page. 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 may result in poor call performance, including longer call setup times and/or poor voice quality. Ribbon recommends maintaining call rates within the performance limits benchmarked below.
