[Freeswitch-users] Random calls failing with WRONG_CALL_STATe when using TLS

Tue Mar 3 15:54:23 MSK 2015

Hey Brian, just saw this message.
There is no other UA in between FS and the endpoint. There is a regular NAT, that's all.
What seems to happen is:
endpoint -> FS: invite = ok
FS -> endpoint: 407 = OK
Endpoint -> FS: invite = Fails with SSL error.

What are the components I should capture to open up a Jira? FS Logs, FS Siptrace, anything else?

Thanks!
