SIP Packet display and capture
sngrep - SIP Messages flow viewer
sngrep is a terminal tool that groups SIP Session Initiation Protocol Messages by Call-Id, and displays them in arrow flows similar to the used in SIP RFCs. The aim of this tool is to make easier the process of learnig or debugging SIP. It recognizes UDP, TCP and partially TLS SIP packets and understands bpf filter logic in the same way ngrep and tcpdump does.
