Hi, outgoing CANCEL is not in sip trace even if setflag(22) and sip_trace is used. I saw that there was some issue relating to http://lists.sip-router.org/pipermail/sr-dev/2011-September/012793.html , but I have the nightly build installed - compiled on 07:10:51 Nov 4 2011 with gcc 4.6.1 and there is still the problem.
