Hello,
Still using Kamailio 1.5.4.
What behaviour should the tm module be doing? Is it doing the RFC behaviour where the CANCEL is only sent after a provisional reply is received or is it doing some other non standard action ?

Hello,
I had a look at RFC 3261, section 9.1. The trouble is that Kamailio is answering "100 Trying" to the caller, so the it is ok for the caller to send back a CANCEL request. Trouble is Kamailio forwards the request to the called user even though the called user never sent a provisional response.
Since the Kamailio server never received a provisional request, it is therefore incorrect for it to forward the CANCEL request to the called user. ( correct me if I am wrong ).
Try 3.0 (kamailio or sip-router). You can control how unreplied branches are canceled, see http://sip-router.org/docbook/sip-router/branch/master/modules/tm/tm.html#ca...
