Overview

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.
