Hiya, I'm not sure if this issue rather belongs to the dev-mailinglist instead of the users' one but since it's just a question and not some sort of contribution I'll try here first:
I've looked at the UDP code (in apps/udp.cc) and came to realize that everytime the sendmsg() function is called a RTP header is put on top of the packet, including (talk burst) flags, sequence number, and a time stamp. Just wondering: What's the rationale behind this? Cheers, --Timo
