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? -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
