Hi All, I just wanted to know if,
a Route/Record-Route header should be sent in the ACK to a 4xx response code as it is a local acknowledgement & not to the other UAC. Section 13, 17, 16.12.1 , 20.30 & 20.34 doesnt not say anything about this. Could you please let me know help if the Route field below in ACK for a 4xx reponse is correct?
