[Freeswitch-users] SRTP breaks my TLS session

[Emrah]

Hello all,
Pinging the list in search of brilliant minds for more recommendations on how to solve this overwhelmingly frustrating issue.

I just love FS and all it lets me accomplish. But this bug and the unpredictability and inability to effectively troubleshoot just leaves a bad impression, accentuated by the fact that no one seems to care about it. I call it a bug because I do not experience this issue with other SIP servers.

Who is available to exchange SIP credentials in order to cross-test this? Especially if you believe you are immunized!

Best,
Emrah
