I have a Kamailio setup infront of a SIP system that do not handle cancellation of a INVITE correctly.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
The system sends out a BYE request instead of a Cancel request on non connected dialogs.</div>

I am trying to find a way to let Kamailio "translate" the BYE request to a Cancel reqeust for the ongoing INVITE dialog.</div>

Alternative if SEMS b2bua can do it, but currently it replies: "not sip-relaying BYE in not connected dlg", and I have not found any obvious way to rewrite it there.</div>

Any thoughts. I can not change the behavior of the remote system.</div>
