Hi guys,
Trying to get to the bottom of some conference bridge issues I'm having with running the system in AWS.
We're hearing a bunch of snap-crackle-pops in conference bridges and when I tcpdum on the server itself I see them in the RTP and see RTP timestamp problems.
I've run the following:

are the xenU kernel settings screwing me here?
