Sergio, Outbound expects that rport is used in the via header for routing of responses (for UDP that is) see the note in section 4.3. Responses are routed as defined in 3261 for TCP.

In "5.3. Forwarding Requests (outbound08)" I read that a Request is forwarded to a flow using the information retrieved from the flow token (and that it is found in the Route-header). Now I am considering how is the case for Responses. Should we consider the same behavior? i.e. forward a Response over a flow using the flowtoken found in the Path-header? In 'non-outbound SIP', as far as I understand, Route Header forces the routing in Requests, and Via-header forces routing in Responses. So... should we avoid any consideration to the information stored in the topmost Via-header when proxying a Response? (And instead use the information in the flowtoken ?) I think that the answers is yes, since the Via could contain a private address in the case of a NAT in the middle. Then, shouldn't be mentioned the response case in the draft?
