Hello, can you try with master branch or with the patch from the next commit? * https://github.com/kamailio/kamailio/commit/aa6e9963b2725c1b6b7e5ff995a77c2… If all ok, then I can backport to stable branches.

I have a follow up question on this. Now that the From tag works as expected I'm not getting a "400 Bad Request" for the CANCEL being created by the t_uac_send inside a failure_route anymore. But now i'm getting "481 Call/Transaction Does Not Exist" Since the from header and tag, to header, Call-ID and CSeq all matches the original INVITE I suspect that is because the Via header branch parameter in the CANCEL doesn't match the one from the original INVITE. There is a way to make it matching?
