Hi!
I have create tool to visualise protocols conversations like SIP, Diameter, GTP, CAMEL, etc. in pcap using PlantUML sequence diagrams. And optionally integration with Wireshark. Tool can be found in GitHub:
https://github.com/dgudtsov/pcap2uml
May I ask to include link to this tool into running page? -
