Gonzalo,
comment inline.
If re-INVITE rejected, I think, it doesn't influence the remote
target.
see the reference to RFC 3261 in the draft regarding atomicity.
A B
INVITE/200/ACK <----------------->
Contact: A1
reINVITE/18x <----------------->
Contact: A2
UPDATE/200 <----------------->
Contact: A3
4xx/ACK <----------------->
You say that A's Contact(local target) is rolled back to A1.
Is this right?
yes.
Therefore, I think that "removing the precondition" is not allowed.
Is this wrong?
the precondition phase is over. The preconditions were already met. All
you are doing is indicating that the stream is in use in the most
backwards compatible way we have.
Cheers,
Gonzalo
