Hello. Here is the result of the ifconfig eth0 | grep 'inet':
inet addr:190.32.5.8 Bcast:190.32.5.255 Mask:255.255.255.0
inet6 addr: (my_ipv6):5990/64 Scope:Link
My server is basically a virtual dedicated server, i think you are right
about my network scenario.
I looked up the patch, and re-checked the rtpproxy source from git, it
loooks like it is ok with supporting -A option. I ran the proxy like so:
sudo rtpproxy -d DBUG:LOG_LOCAL5 -f -s udp:localhost:12221 -u
rtpproxy:rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -A 185.48.5.9 -m 16384
-M 32768
And the same problem still remains, here is the debug output:
DBUG:get_command:GLOBAL: received command "3165_12 Lc113,101

22646/17854 is cleaned up
I guess now that it's some sort of ACK packet issue on opensips side ( only
using tls , using the udp,tcp evrything works fine).
