<tt>Hi,<br>
<br>
The first duplicate INVITE is a a retransmission as the B party
did not reply with anything back.<br>
<br>
Now, the multiple 200 OK + ACK may be either because of network
delays, either because the ACK is badly routed and never hits the
UAS, so the UAS is retransmitting the 200 OK reply.<br>
<br>
Is the BYE automatically generated by one of the devices or it is
your actual hung up ?<br>
<br>
Regards,<br>
</tt>
