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
