Hi,
I don't think the draft forbids you from using 4xx to re-INVITE, but it explains the disadvantage of doing so if you have committed changes.
Regards,
Christer

	I think I explained why I can use 4xx of Re-INVITE, without making anything ambiguously. 		The point is that do you agree that later UPDATE/200OK commit the target refresh. 					Gonzalo Camarillo <Gonzalo.Camarillo@xxxxxxxxxxxx>

	Hi,		> [Gao] I just wanted to say if UPDATE/200OK committed the target refresh, 	> it should be free for 4xx of Re-INVITE.		I insist. You should re-read the draft. It explains why you should not	use 4xx response to cancel changes. The advantage of the approach in the	draft is that it does not require normative changes to already	implemented specs. It is more a BCP kind of spec. That is why its	backwards compatibility properties are good.
