CallMeter review
A focused platform for measuring, testing, and monitoring SIP and VoIP quality.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CallMeter is a web-based SIP testing and VoIP analytics platform for teams operating voice or video infrastructure. It generates real SIP calls and measures voice, video, RTP, timing, and network-quality data. The platform supports synthetic call testing, SIP trunk monitoring, MOS scoring, jitter tracking, and packet-loss tracking, making it suited to teams that need active quality validation rather than passive call reporting. It is available through the web, REST API, and self-hosted workers.
Its strongest differentiator is the depth of testing in one product. CallMeter provides 90+ real-time metrics per endpoint, direction, and second, with MOS scoring based on the ITU-T G.107 E-Model. Teams can schedule caller and callee probes, run configurable SIP load and stress tests, and inject packet loss, jitter, latency, or bandwidth impairments. SIP message capture and ladder diagrams support investigation, while threshold-based health states, webhook notifications, public status pages, and rolling uptime data extend the platform from diagnosis into ongoing service monitoring.
CallMeter also fits environments with varied deployment requirements. Cloud-managed or on-premise workers can support testing traffic that cannot leave a private network, while REST APIs and CI/CD quality gates connect voice-quality checks with delivery workflows. Pricing is custom and based on concurrent call capacity and testing frequency, so the product suits organizations planning a defined testing program rather than buyers seeking a public, self-serve plan. Choose CallMeter for detailed SIP quality engineering and continuous monitoring; consider an alternative if you need AI features or a broader observability focus.
