Version is: FreeSWITCH Version
1.5.13b+git~20140529T194631Z~0d7b1ff42a~64bit (git 0d7b1ff 2014-05-29
19:46:31Z 64bit)
Since I cannot reproduce this at will, I would need to upgrade my
production to the latest master to try to reproduce it there.
The client is WebRTC with JsSip on Chrome 34.
I do not enable proxy_media and in fact there is no reference to
proxy_media anywhere in my config.
Similarly, I did not change anything related to timers but if you;d like me
to check a specific setting, I'll be happy to.
I still have that FS instance running, so if there is anything else I can
do to help track this down, please let me know.
