What are the best ways to measure audio quality in a telecoms network?

Spearline Testing

However, in digital networks, carriers have the ability to transcode audio quality from excellent quality codecs like G711 to lower quality codecs such as G729 or GSM. Nowadays, this measure is still in use, but a score is generated by analysing network performance metrics such as packet loss, jitter and latency. GSM or above.
