Hi all,
 
I have a question regarding following scenario: my server is acting as a proxy that does record-route, ie it wants to be kept in the path for future requests. When the proxy receives a re-INVITE, it will pass the re-INVITE to the other end. The question is, if the proxy is allowed to send a provisional response to the transmitter of the re-INVITE in order to stop the retransmission of the re-INVITE and also to avoid that the transmitter of the re-INVITE drops the call if it takes too long for the other end to send the 200 response to the re-INVITE. 
 
Thanks,
Jesus
