At this point, I would really like to know a *real* case of usage in
which the UAC receives two (or more) 200 OK and it's useful for it.
This is:

a) When the second 200 arrives to the proxy, the proxy sends ACK and BYE.
b) The proxy relays the second 200 to UAC.

I would like to know why b) could be useful for a UAC.
