Subject: [rtcweb] Same answer in a provisional and a final response
Precedence: list

Hi,

with respect to today's discussion during the face-to-face session about
whether a SIP UAS needs to place the same answer in a final response as
it placed in a previous provisional response, this is the relevant text
in RFC 3261:

http://tools.ietf.org/html/rfc3261#page-80

        "If the initial offer is in an INVITE, the answer MUST be in a
         reliable non-failure message from UAS back to UAC which is
         correlated to that INVITE.  For this specification, that is
         only the final 2xx response to that INVITE.  That same exact
         answer MAY also be placed in any provisional responses sent
         prior to the answer."

Cheers,

Gonzalo
