Hi, Its legit operation, in fact the route-set on the UAC would be updated from the values of the Record-Route headers in the responses from UAS. Unless there's a Record-Route in the responses, your device would never know what route to use for future in-dialog requests.

Hi All, Record route is normally added in Request. I have encountered a weird case that INVITE from my sip device did not have Record-Route, but the response of 180 and 200 have Record-Route. I could not find if it is legit to add Record-Route in response from RFC 3261. INVITE without Record-Route ------------------> <----------------- 183 with Record-Route <----------------- 200 with Record-Route Please let me know if it is legit to add Record-Route in response?
