What if you get a bad score?
MultiDSLA provides smart analytics to identify all influences and root cause

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!

The MultiDSLA Controller centrally automates call set up and measurements between any MultiDSLA Nodes in your voice network. Tests occur according to a pre-defined schedule or on demand with a simple to use graphical representation of the network.

MultiDSLA offers unrivalled ease of use and can perform the most complex test processes, controlling 100+ Nodes.

The MultiDSLA Nodes are capable of generating voice signals at any level, and measure the key performance indicators configurable via the controller. Any selection of node types can be configured. The user interface is consistent and the test process remains identical, regardless of which node types are being used, making the system easy to learn, easy to use and supremely flexible.

Configure a system for your test application - VoIP service to analogue PBX, mobile to PRI, soft phone to POTS, BRI to Bluetooth, and so on.
