> Use OPERA to...
evaluate the perceived voice quality of new components,
understand the causes for noise, drop outs, distortions, echoes and artefacts of complex non-linear systems,
optimize parameter settings such as level, bit rate, compression type, filtering, jitter buffering, error concealment etc.
assess the perceived end-to-end quality of systems and networks in the planning stage and during development,
benchmark the quality of deployed networks carrying voice and music signals,
objectively characterize your network QoS compared to others and leased lines (SLA monitoring),
