Hi,
I'm trying to write a small scenario to simulate a basic SIP call, using
SIPp.
I have an error, the proxy between the two SIPp instances sends back a
481 message on the BYE.
I probably missed something.
I found a similar problem in the mailing list archive but can't
determine the error in this case.
Maybe it's an error with some tags parameters, or branch in the Via
header.
Here are the messages sent or received by the caller. Registrations have
been done for both caller and callee
FYI : the "_" at the end of lines come from the log file, they are
not present in the real messages.

Any idea where the error could come from?
