Record-Route header is used to send subsequent requests after dialog is established. If Invite is rejected with an error response, there is no dialog and no need for RR header in error response. You can refer to Table 3 in RFC 3261

I am bit lost trying to find the right explanation. I am specifically looking for a case where a proxy inserts a Record-Route header in the outgoing invite and the UAS rejects the INVITE with some 5xx or a 4xx response. Now would the 4xx or 5xx response carry the R-R headers from UAS to the proxy and then back to UAC? I have generally seen the implementations where 100 doesnt carry and 18x carries it. thanks Manpreet _______________________________________________ Sip-implementors mailing list Sip-implementors@cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list Sip-implementors@cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
