draft-ietf-sipping-cc-transfer section 5 tells us that we can use GRUUs to associate an out-of-dialog REFER to an INVITE dialog usage.
Using that same logic, could one do the same with a BYE? That is, if I've set up a call using a GRUU (*) and I receive an out-of-dialog BYE sent to that GRUU. Should I just drop the BYE saying "sorry, 481"? Should I accept the BYE as being "equivalent" to an in-dialog BYE (in the sense that an in-dialog REFER and an out-of-dialog REFER are equivalent: doing the same thing)? REFER uses Target-Dialog as a means of authorising the request, so what if one received an out-of-dialog BYE targetting one's call's GRUU, with Target-Dialog? I'm tempted to just say "it's not an in-dialog BYE; reject it"; after all, RFC 3261 says 15.1.1 UAC Behavior A BYE request is constructed as would any other request within a dialog, as described in Section 12. Any thoughts? frank (*) Confession: my stack only implements version -10, not -11 (at the moment, at least). Perhaps I use obsolete terminology above; I hope not! _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
