In their own words
CallMeter
CallMeter is a SIP stress-testing and VoIP analytics platform for evaluating, monitoring, and benchmarking voice infrastructure. It measures more than 90 real-time quality metrics for each call, second, endpoint, and direction. Configurable load tests can vary endpoint counts, SIP methods, authentication, and call duration, and capture SIP messages as ladder diagrams. Supported media includes audio codecs such as PCMU, PCMA, G.722, Opus, G.726-32, GSM, Speex, AMR, and iLBC, alongside H.264, H.265, VP8, and VP9 video.
Continuous probes can run as caller or callee on intervals or cron schedules, apply quality thresholds, track sliding-window status, and send webhook notifications. A REST API supports test runs, metric retrieval, probe management, and CI/CD quality gates for GitHub Actions, GitLab CI, and Jenkins. Users can choose managed cloud workers or Docker-based workers in private networks. With user-owned workers, SIP signaling and RTP media stay in the customer network; only aggregated quality metrics leave it. Pricing is on request. The seven-day free trial requires a valid payment method and becomes a paid subscription unless cancelled before it ends.
Telchemy SQmediator
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.
