| Deployment | The project provides a single-container deployment and says the container must run privileged with host networking to access eBPF and the network interface. | The sniffer is a static binary that runs on Linux, and the maker lists builds for x86, ARM 32-bit and ARM 64-bit. |
| Integrations | The Prometheus-format metrics are documented as compatible with Prometheus, VictoriaMetrics, Grafana Cloud, and other Prometheus-compatible scrapers. | The site lists compatibility with Kamailio, OpenSIPS, FreeSWITCH, Asterisk, Cisco, Avaya, Genesys, Mitel, AudioCodes, Ribbon and Oracle SBC. |
| Purpose | sip-exporter is an open-source eBPF sensor that turns SIP signaling and correlated RTP traffic observed on a Linux host into Prometheus metrics and Grafana dashboards. | VoIPmonitor is an open-source packet sniffer with a commercial web GUI for monitoring, troubleshooting and recording VoIP/RTC calls. |
| Support | The project directs users to GitHub Issues for support, bug reports, and feature requests, and to its security policy for private vulnerability reports. | Support is included with the WEB GUI license, and the maker lists free deployment assistance. |

In their own words
sip-exporter
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.
VoIPmonitor
VoIPmonitor is an open-source packet sniffer paired with a commercial web GUI for monitoring, troubleshooting, and recording VoIP and RTC calls. It reports MOS, jitter, packet loss, delay, and RTCP data. Recording includes calls and SIPREC sessions, with policy-based retention and deletion rules. Troubleshooting tools provide packet captures, SIP ladder diagrams, audio waveforms, spectral analysis, and TLS/SRTP decryption. The GUI adds dashboards, OLAP analytics, scheduled reports, KPI alerts, and fraud-detection rules. Listed compatibility includes Kamailio, OpenSIPS, FreeSWITCH, Asterisk, Cisco, Avaya, Genesys, Mitel, AudioCodes, Ribbon, and Oracle SBC. Supported protocols include SIP, RTP, RTCP, SIPREC, SKINNY, MGCP, SS7, SCTP, WebRTC, Diameter, TCP, SSL, and TLS. The sniffer runs as a static Linux binary with x86 and ARM builds. Cloud CDR retention is 21 days, PCAP remains on the customer server, and the listed maximum is 2,000 channels. Cloud 3 channels costs $22 a month; On-Premise 10 channels costs $45 a month.
