Bicom Systems SIP Monitoring (sipMON) vs CallMeter

Bicom Systems SIP Monitoring (sipMON) is a Linux, self-hosted tool for ITSPs and PBXware environments. It captures SIP signaling and RTP traffic, tracks calls, and stores call-detail records in an ODBC-supporting database. Quality analysis covers jitter, delay variation, packet loss, and MOS-based call-quality prediction. Configurable alerts can flag problems for response. SIP and RTP packets can be saved as individual PCAP files for analysis or export. sipMON can record calls, decode speech, play it in its interface, or save audio as WAV. G.711 alaw and ulaw are listed, with commercial plugins for G.729a, G.723, iLBC, Speex, and GSM. CDR details may include duration, codec, caller information, SIP agent, last SIP response, RTP source addresses, MOS, delay and loss distributions, and download commands for WAV or PCAP files. The maker describes its C++ program as handling thousands of simultaneous calls. Ongoing-call monitoring is beta and requires the latest sipMON with TCP manager access enabled. Pricing is on request.

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.
