It looks like those BYE sipp is sending are automatic BYE sent upon reception
of unexpected messages. Indeed, those messages are hardcoded (this is no longer
the case in the very latest trunk versions) and the Max-Forwards flag was
missing (this has been corrected in the 3.0 version, for which no Windows
package has been delivered yet).
You should first check on sipp side what's going on (trace_msg and trace_err
logs would help).

Objet : [Sipp-users] Missign Max-Forwards , and strange ACKs, not related to
the scenario
I didnt find anythng on google so posting here:
sipp 2.01 - windows
Im running simple scenario
INVITE -->
100 <--- OPTIONALL
180 <--- OPTIONAL
OK <-----
ACK --->
pause 10s
BYE --->
OK <----
Before that UAS and UAC users are registered at the proxy
Two things happen now:
1. Proxy receives BYE without Max-Forwards - this can be easly hacked on proxy,
but its a hack

(this is content of message read directly from socket)
2. Proxy receives strange requests, which can loop around proxy unless it drops
them.
