About sngrep
sngrep displays SIP call message flows in the terminal using an ncurses interface. It can capture SIP packets live and show calls as they happen, or open existing PCAP files for later analysis.
Calls are listed and can be opened into a flow view showing each SIP message between endpoints. It suits VoIP administrators and developers troubleshooting call setup on Asterisk, FreeSWITCH or other SIP systems. It is a different tool from ngrep and dnGrep.
