MultiDSLA vs Telchemy SQmediator

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.

Telchemy SQmediator monitors and troubleshoots real-time performance for VoIP, video, and data services. It combines passive quality monitoring with active tests, reporting MOS experience scores, QoS metrics, and diagnostics for voice, audio, and video sessions. Listed meeting services include Microsoft Teams, Zoom, Google Meet, GoToMeeting, and Webex; the system can analyze encrypted audio and video streams without decrypting them. Linux, Windows, and Android test agents can simulate calls and test web, email, DNS, DHCP, and SIP services. Dashboards, email alerts, and SNMP traps can flag configured threshold breaches. The multitenant system is designed to manage thousands of customers and sites and millions of end users. It runs on Linux server hardware or virtual machines, on premises, in the cloud, or in data centers. An Oracle or PostgreSQL database is required, and customers set it up themselves using Telchemy's scripts and instructions. Pricing is available on request. Licensing depends on modules, and combining passive monitoring with active testing costs extra.
