Redirection with TCP

Hi,

I've made up a little conferencing service which issues a 302 Moved 
Temporarily to a certain conferencing URI after being invited. The 
client then sends an INVITE to this URI. This works if UDP is used, and 
also worked with TCP using the "old" 1.1, but with the new version from 
CVS it doesn't work with TCP. The new INVITE packet arrives at the 
conferencing host and is acked by TCP, but it doesn't seem to arrive at 
the stack.

Below is an excerpt from the debug log. The client stack has sent an ACK 
to the 302 Moved (which is correct behavior, I think). The server stack 
seems to fire a timer, but I cannot make more out of the debug log, sorry..

Maybe you can help me out of this. Should the new INVITE be sent to a 
different TCP connection to be successful? Or is there any other thing 
that must be kept in mind when using TCP?

I may also send more information about the single messages exchanged, if 
you're interested.

Best regards,
Verena
