Hello,<br><br>yes, CANCEL in stateful relaying are re-generated hop by hop. There is a way to propagate headers from invite to cancel via:<br><br><a href="http://kamailio.org/docs/modules/stable/modules/tm.html#ac_extra_hdrs">http://kamailio.org/docs/modules/stable/modules/tm.html#ac_extra_hdrs</a><br>
<br>Do you want to add own headers or is about the reason header -- this one is added with latest versions:<br><br><a href="http://kamailio.org/docs/modules/stable/modules/tm.html#local_cancel_reason">http://kamailio.org/docs/modules/stable/modules/tm.html#local_cancel_reason</a><br>
