hi all,
Which is the kernel version of the amazon instance? There was some minnor
net issues with incorrect checksum that affected 2.6.18. You can disable the
checksum with ethtool
ethtool -K [intercace] tx off
Try above command and check whether the debug message disappear.
Hope it helps,
Samuel.

Hi
I have installed Kamailio with MediaProxy and asterisk on Amazon Server..
While kamailio/MediaProxy and Asterisk both running on different amazon's
instance.
Kamailio : 1.5.0-notls
MediaProxy : 2.3.8
Asterisk : 1.6.2.6
Firewall port is opened for mediaproxy from 10000-20000 (UDP), 5060 (UDP)
etc on both amazon machine..
while I tried to play an audio... it plays sound file but unable to found
audio on device.
when I put tcpdump on asterisk machine it gives following error...
# tcpdump -i eth0 udp portrange 10000-20000 -w test1.pcap
