While PESQ scores can definitely determine if there were problems or not in a call, many of you need to determine what was the cause of a poor quality call. The Single-Carrier Voice Quality Graph shows relationships of key technology parameters that are known to have a direct effect on speech quality, such as: Speech Codec, Error Rate, Signal level and interference.

Multi-Carrier Benchmarking

This new analysis tool lets you compare multi-technology multi-carrier performance. Compare up to 10 different carriers through PESQ, a reliable, objective and accurate audio quality benchmark.

The Multi-Carrier Benchmarking window allows you to monitor both PESQ and network errors (Setup Failures and Dropped Calls) that impact speech quality.
