What is MultiDSLA?

MultiDSLA is Opale Systems’ flagship voice quality test system, widely recognized as the reference measurement platform for QoS and QoE validation in telecom networks.
It enables operators, equipment vendors, and test labs to assess voice service quality across fixed, mobile, and IP networks, from development to live operations.

By combining objective MOS scores (PESQ®, POLQA®) with advanced analytics, MultiDSLA not only measures end-user experience, but also helps identify the root causes of degradations.
