Hi,
I have a question related to handling Responses that are going to be
sent over a flow in an Edge proxy.
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?
Regards,
Sergio
