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...
A question about case 2:
----------- 2 will send and retransmit CANCEL even on unreplied branches, stopping the request retransmissions. This has the same advantages as 1 and also avoids the extra roundtrip in the case of the provisional reply, but it's not RFC 3261 conforming (the RFC allows sending CANCELs only on pending branches). ------------
What about if the UAS replies a 200 before the CANCEL arrives to it? Would TM route the 200 upstream to the UAC? or would TM absorb it?
