Hi All The only statement which is close to this is below, but this is for ACK for 2xx Reponses. But Route/Record-Route field in ACK for 4xx responses is not specified.
*o Usage of Route in CANCEL and ACK was not well defined in **RFC 2543*<http://www.faqs.org/rfcs/rfc2543.html> *. It is now well specified; if a request had a Route header field, its CANCEL or ACK for a non-2xx response to the request need to carry the same Route header field values. **ACKs for 2xx responses use the Route values learned from the Record-Route of the 2xx responses. * So if anybody knows any information regarding this, kindly respond to me.
