Mitko:
I am not sure I would classify these as bugs per say. Please note SIPp does
not "know" much about SIP semantics like transactions and such.You can
typically get around the issue #1 below by storing CSEQ values in variables
at relevant points and they replay them back in correct messages.
Issue #2 is really how the last* variables work in SIPp. You should
typically not be using last* if you do not want SIPp to use stuff it
received in the last incoming request.
Thanks,
Venkatesh
