You are assuming that:
- There is a proxy between the UAC and the UAS (GW).
- The proxy does not route the request to another proxy.
- The UAS just inspects the top most Via.
- The proxy does not inspect the top Via added by the UAC (if not it
could reject the request).
First of all, a proxy could inspect ALL the Via headers, for example
in order to detect spirals or loops as RFC 5393 states.
Anyhow, we are not discussing about that. Tomorrow I will paste the
malformed SIP request that Kamailio forwards to the GW.
Cheers.

If the Via header is invalid, then the Proxy/UAS
*cannot* reply to the
request, or not in every cases. Theorically the Proxy/UAS replies to a
request based on the information in Via header.
since via header was added by your sip proxy, it is valid and the uas
should be able to respond to the request. if it is does not, show me
where is rfc3261 it is written and uas does not need to respond to such
a request.
