Does HEP send verto signaling info to Homer too? On 10 May 2017 at 21:38, Daniel Greenwald <dig1234@gmail.com> wrote:
Thanks for this script! Theoretically it is possible to see TLS SIP traffic with freeswitch sending HEP to Homer. But there seems to be a bug in FS that only sends one side of SIP conversation (ie the FS side, not inbound messages)..

Thank you Giovanni, that is a useful tool - we will document it in the OpenSIPS TLS tutorial, so other can benefit ;)
Glad about it! Be sure to get it from https://freeswitch.org/conflue nce/display/FREESWITCH/Packet+Capture#PacketCapture-TLSwithsharka , is the latest version with a couple fixes.

For a cut and paste ready version, that has the correct carriage returns (mangled by mail), check it in FreeSWITCH documentation:

Hello fellows,
after some experimentation with various tools, I come out with a little shell tool that maybe can be useful to you too.
It can only work with non-forward secrecy ciphers, obviously, and only if is started before the client do the initial TLS handshake (eg, just restart the client). Forward secrecy cannot be decrypted after fact, so don't waste effort.
An example of ciphers that can be decrypted are the "AES256-SHA" openssl cipher group. You can use ssldump to check what cipher is used by serverhello.
Enjoy, make it better, and share it :)
