MultiDSLA vs Sipfront Probe

MultiDSLA is a measurement system for voice quality testing and performance assessment, spanning core technology development through network operations. It produces objective MOS scores based on ITU-T PESQ and POLQA standards, alongside measures for one-way delay, packet loss, jitter-buffer behavior, echo, speech and noise levels, codec distortion, VAD performance, call setup, and DTMF sequences. Its Controller automates call setup and measurements on demand or on a schedule through a graphical network representation, controlling more than 100 nodes. Nodes connect through analog and handset interfaces, SIP/RTP networks, and mobile phones. Users can define KPI pass/fail criteria and monitor measures such as delay, jitter, MOS, echo, and speech levels. Field testing supports fixed-line-to-mobile or mobile-to-mobile calls with GPS localization and synchronization and Google Earth mapping. The system offers online speech-to-text access and REST API and Python module support for automation integrations. The Controller supports specified Windows Server and desktop versions; its datasheet also lists smartphone call control through an Android app. Pricing is available on request.
