Use PESQ testing to reliably validate and enforce SLAs, monitor the quality of voice services, provision new services, and troubleshoot quality issues over a wide variety of networks such as VoIP, PSTN, PacketCable, WiMax and cellular. In addition to listening MOS, the PESQ Test Agent also measures over 30 other speech quality metrics, including clipping events, noise, loss and speech power, as well as packetlevel measurements such as packet loss, jitter and latency to fully capture impairments caused by codecs, VADs, and analog lines. Call progress analysis provides signaling and call statistics, including cause location and value for abnormally terminated calls.
