[Freeswitch-users] [OpenSIPS-Users] TLS SIP packet tracing and visualization

Fri May 12 22:37:21 MSD 2017

Giovanni- I personally experience this issue on three different systems.
I've tried all hep versions, and confirmed not a homer issue via wireshark.
ie the HEP is not being sent for Inbound TLS messages. I did report it to
Jira in Oct 2016 but got little attention. I still find HEP useful for
outbound messages but it would be really nice to have two way SIP
conversation in cleartext...
