Overview
Capture all influences on your voice quality
MultiDSLA solution is a state of the art measurement system for Voice Quality Testing and Performance Assessment used by many organisations as the reference measurement in applications ranging from core technology development to network operations.
In addition to objective and undisputable voice quality scores such as PESQ & POLQA MOS, MultiDSLA offers smart analytics and key performance indicators to help you identify the root cause of distortions in the degraded voice signal:
- Network impairments : one-way delay, packet loss, jitter buffer behaviour and echo,
- Speech & Noise level,
- Codec distortion,
- Voice activity detector (VAD) performance,
- Call setup analysis,
- DTMF sequences,
- And many more!
Most versatile voice quality test solution
The MultiDSLA Controller centrally automates call set up and measurements between any MultiDSLA Nodesin your voice network. Tests occur according to a pre-defined schedule or on demand with a simple to use graphical representation of the net work.
The MultiDSLA offers unrivalled ease of use and can perform the most complex test processes, controlling 100+Nodes .
