Hi Michael,
that's exactly the trick I wanted to try to solve this issue (see my
previous email)...but I will have to dig to see how difficult is to
implement.

Hi Klaus,
I guess, you're right. I didn't know that.
Then openser should keep CANCEL in transaction context until transaction
expires (probably until wt_timer expires) and transmit it if provisional
response is received during that time.
Thanks for clarification.

Hi Michael!
RFC3261 page 54:
If no provisional response has been received, the CANCEL request MUST
NOT be sent; rather, the client MUST wait for the arrival of a
provisional response before sending the request.
Thus, the proxy should withhold the CANCEL until a provisional response
is received. If no provisional response is received for a certain time,
the proxy may discard the whole transaction.
Also take a look at section 16.10 and section 16.7 step 10.
regards
klaus
