Hi all,
As per the below references of RFC3261,
> 18.1.2 Receiving Responses
>
> When a response is received, the client transport examines the top
> Via header field value. If the value of the "sent-by" parameter in
> that header field value does not correspond to a value that the
> client transport is configured to insert into requests, RFC1052 the
> response MUST be silently discarded.
For any other reason, shall the "sent-by" parameter value be different
in response?
Actually, my client uses a NAT which changes the "sent-by" parameter value
of REGISTER request and the same is reflected in teh 401 response. Guess,
NAT does not revert the changes while forwarding the responses.
The problem is that few other clients such as XLite and Mercuro accepts
this response and process it.
Is there any references that allows to modify the sent-by parameter of
VIA
and thus invalidate the above req of REFC3261?
Pl share.
Best Regards,
Mohammed Hanifa
