Right; ACK for a 2xx class response for an INVITE is a separate trans-
action and may follow a different path then did the INVITE. The issue
being discussed in previous emails is what are the ramifications if
a UAC misbehaves and sends an ACK directly to a UAS regardless of R-R
received in the 200 OK.

Right.
