Apologies, if this has been asked before. I have searched through RFC 3261 to find out whether 2xx responses to re-INVITE and ACK to such 2xx should be retransmitted end-to-end as is the case for initial INVITE. I have not been able to clarify this question from the text.
Here my findings: section 14 of RFC 3261 does not address this issue explicitly. I have been able to find only one sentence possibly relating to this issue, namely the last sentence of section 14.1: "The rules for transmitting a re-INVITE and for generating an ACK for a 2xx response to re-INVITE are the same as for the initial INVITE (Section 13.2.1)." End-to-end retransmissions, however, are explained in sections 13.2.2 and 13.3.1 rather than in section 13.2.1.
