MultiDSLA
MultiDSLA is a voice-quality measurement system for work ranging from core technology development to network operations.
What MultiDSLA is
MultiDSLA is a voice-quality measurement system for work ranging from core technology development to network operations. It produces objective MOS scores using ITU-T PESQ and POLQA, and analyzes measures including delay, packet loss, jitter-buffer behaviour, echo, speech and noise levels, codec distortion, VAD performance, call setup and DTMF sequences. Its Controller can schedule or initiate call setup and measurements through a graphical network representation while controlling 100+ nodes. Nodes connect through legacy analog and handset interfaces, SIP/RTP networks, and mobile phones. Users can set KPI pass/fail criteria and monitor measures such as delay, jitter, MOS, echo and speech levels. Field tests support fixed-line-to-mobile or mobile-to-mobile calls with GPS localization and synchronization and Google Earth mapping. The system also offers speech-to-text access, plus REST API and Python module support for automation integrations. The Controller supports specified Windows Server and Windows desktop versions, and its datasheet lists smartphone call control through an Android app. Pricing is available on request.
