Project Summary
Sipgrep is a powerful pcap-aware tool command line tool to sniff, capture, display and troubleshoot SIP signaling over IP networks, allowing the user to specify extended regular expressions matching against SIP headers.
The first version of this program (dated 2005) was a small wrapper for ngrep. Version 2.x provides a full standalone application with numerous additional features geared towards SIP, building upon the excellent ngrep code baseline.
