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.
HOMER
HOMER is a free framework for capturing VoIP and real-time communications traffic for analysis and monitoring. Its listed tools include search, end-to-end analysis, and packet drill-down, together with call-flow and PCAP capture, statistics, analytics, a REST API, and widgets. Capture agents support HEP3 encapsulation, payload encryption and compression, and TLS. The listed core covers SIP, RTCP, RTCP-XR, WebRTC signaling, and log collection. HEP/EEP integrations include Kamailio, OpenSIPS, Captagent, Asterisk, FreeSWITCH, RTPEngine, sipgrep, sngrep, and hepipe. HOMER 11 is described as an all-in-one HEP capture and API server for the 11.x data lake, with ingest, DuckLake storage, a Node using FlightSQL, and a Coordinator with a REST API. Docker is supported, and the project uses the AGPL-3.0 License. The maker presents HOMER for ITSPs, VoIP providers, and trunk suppliers. Commercial development support, 24/7 SLA production support, and advanced training are available by quote.
