MultiDSLA vs sip-exporter

MultiDSLA is a measurement system for voice quality testing and performance assessment, spanning core technology development through network operations. It produces objective MOS scores based on ITU-T PESQ and POLQA standards, alongside measures for one-way delay, packet loss, jitter-buffer behavior, echo, speech and noise levels, codec distortion, VAD performance, call setup, and DTMF sequences. Its Controller automates call setup and measurements on demand or on a schedule through a graphical network representation, controlling more than 100 nodes. Nodes connect through analog and handset interfaces, SIP/RTP networks, and mobile phones. Users can define KPI pass/fail criteria and monitor measures such as delay, jitter, MOS, echo, and speech levels. Field testing supports fixed-line-to-mobile or mobile-to-mobile calls with GPS localization and synchronization and Google Earth mapping. The system offers online speech-to-text access and REST API and Python module support for automation integrations. The Controller supports specified Windows Server and desktop versions; its datasheet also lists smartphone call control through an Android app. Pricing is available on request.

sip-exporter is a free, open-source Linux and self-hosted eBPF sensor for SIP and correlated RTP monitoring. It exposes Prometheus metrics at /metrics, including SIP traffic, active sessions, RFC 6076 performance, voice quality, RTP, RTCP, fraud, and diagnostic measures. RTP analysis covers jitter, packet loss, packet-delay variation, and E-model MOS; RTCP sender and receiver statistics include loss, jitter, and round-trip time linked by SSRC. Documented fraud indicators include registration scans, INVITE bursts, account takeover after a registration country change, and False Answer Supervision. A Grafana dashboard has 11 sections, with Prometheus alert examples and Alertmanager examples for Slack, PagerDuty, and email. Metrics are documented for Prometheus, VictoriaMetrics, Grafana Cloud, and compatible scrapers. Deployment uses a single container that must run privileged with host networking. Capture is limited to IPv4/UDP SIP and related RTP/RTCP, and the sensor must see signaling and media on the same call path.
