You can detect VoipMonitor applications using this tool.
VoIPmonitor is open source network packet sniffer with commercial frontend for SIP RTP RTCP SKINNY(SCCP) MGCP WebRTC VoIP protocols running on linux. VoIPmonitor is designed to analyze quality of VoIP call based on network parameters - delay variation and packet loss according to ITU-T G.107 E-model which predicts quality on MOS scale.
An attacker might use the disclosed information to harvest specific security vulnerabilities for the application identified. There is an example exploit checker: https://securityforeveryone.com/tools/voipmonitor-pre-auth-rce-cve-2021-30461
Only use components that do not have known vulnerabilities, only use components that when combined to not introduce a security vulnerability, and ensure that a misconfiguration does not cause any vulnerabilities.
