Hello!
I hawe noticed that Media Proxy is working only when debug log is enabled.
When debug log is disabled, then in "Active Sessions Summary " I can see 2 sessions and in tcpdump I see that packets are comming to server, but nothing comes out from server. When i enable debug log, then all is working fine.
I have tested 3.5.0 and 3.5.1.
Openfire is installed on gentoo box using openfire_src_3_5_x.tar.gz
