Both RFC3261 and RFC2543 say Max-Forwards can only be present in
request,
So I guess no one can blame you if you drop the response.
RFC3261 page 161

Subject: [Sip-implementors] unexpected header in SIP response
Query on such an scenario:
As we know that the Header - Max-Forwards are only for SIP Request
message, however, if the UAC receives a 183 message with Max-Forwards
header present, how the UAC should react to such a response? Should the
call be taken down or go ahead? Is there an explicit description on such
an error handling?
Thanks,
Alex Zhang
