Do you offer excellent Voice Quality?
Voice Quality is, and will remain the major key performance indicator for each operator’s network quality. This is recognized by subscribers and operators alike.
Bad voice quality generates short holding times and repeated attempts. This immediately results in a poor level of user satisfaction. Furthermore, international Voice Quality tests can reveal crucial quality information of different network carriers, the usage of IP routing or SIM boxes and simulate echos to check wether the echo cancellers are configured correctly. Therefore, verification of voice quality is essential. Subjective tests, where human beings would have to score the quality of sound samples in a listening laboratory environment are expensive.
Automated test methods with the intention to mimic subjective tests, allow for a cost effective and consistent alternative to subjective testing, either on a referenced or an unreferenced basis.
