A command-line tool to sniff, capture, display, and troubleshoot SIP signaling over IP networks using regex matching.
Sipgrep is a command-line network analysis tool specifically designed for SIP (Session Initiation Protocol) traffic. It allows users to sniff, capture, and display SIP signaling over IP networks, using regex to filter and match against SIP headers. It solves the problem of debugging and monitoring VoIP communications by providing detailed, real-time insights into SIP dialogs and packet flows.
VoIP engineers, network administrators, and telecommunications professionals who need to troubleshoot SIP-based systems, analyze call quality issues, or monitor SIP traffic on their networks.
Developers choose Sipgrep for its deep SIP-specific features, lightweight console-based interface, and powerful regex filtering that goes beyond generic packet analyzers, making it an efficient tool for real-time VoIP diagnostics and network forensics.
SIPGREP: Display and Troubleshoot SIP signaling over IP networks in console
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automatically tracks SIP dialogs and generates detailed call detail records (CDR) with timestamps and metrics, as shown in the extensive dialog reports example in the README.
Supports extended regular expressions to match against SIP headers for precise filtering of calls, registrations, and responses, enabling targeted troubleshooting.
Can duplicate captured traffic to a HOMER SIPCapture server using HEPv3 via the '-H' flag, facilitating centralized logging and analysis without extra tools.
Lightweight and scriptable, built for fast, console-based SIP analysis without GUI overhead, ideal for real-time monitoring and automation in network operations.
Purely command-line based, which limits accessibility for users who prefer visual packet inspection tools like Wireshark and requires familiarity with terminal usage.
Specialized exclusively for SIP traffic analysis, making it unsuitable for multi-protocol network diagnostics without pairing with other tools like tcpdump.
Requires manual building from source on non-Debian systems and depends on libpcap and libpcre libraries, adding setup overhead compared to packaged solutions.
