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.

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...
