[sr-dev] cancel/ack problems

now that db issues have been solved, i tried make a call. twinkle user test called twinkle user jh, but before jh answered, test canceled the call. i got to syslog: Jun 11 13:03:31 localhost /usr/sbin/sip-router[1727]: INFO: INVITE <sip:jh@test.fi> by &lt;test(a)test.fi&gt; as <sip:test@test.fi> from <192.98.101.10> is authorized Jun 11 13:03:31 localhost /usr/sbin/sip-router[1727]: INFO: Routing first INVITE to <sip:jh_test_fi@192.98.101.10:5074;transport=udp> and <<null>> Jun 11 13:03:33 localhost /usr/sbin/sip-router[1726]: INFO: Relaying CANCEL to <sip:jh@test.fi> Jun 11 13:03:33 localhost /usr/sbin/sip-router[1727]: INFO: Routing in-dialog ACK from <sip:test@test.fi> to <sip:jh@test.fi> Jun 11 13:03:33 localhost /usr/sbin/sip-router[1727]: WARNING: tm [t_lookup.c:1499]: WARNING: script writer didn't release transaction Jun 11 13:03:33 localhost /usr/sbin/sip-router[1727]: NOTICE: Discarding unmatched ACK <sip:jh@test.fi> with same config file, kamailio doesn't give the warning about not releasing transaction nor notice about unmatched cancel. notice comes from this: # Relay CANCEL without further processing if (is_method("CANCEL")) { if (!t_check_trans()) { xlog("L_NOTICE", "Discarding unmatched CANCEL to <$ru>\n"); exit; }; why is cancel not matched? in case mailing list accepts attachments, wireshark dump (which looks good to me), is enclosed. -- juha
