        - that string is a B64 encoded value, so it is case sensitive.
        According to RFC3261, UAs must copy the RR params without any
        change (even if they do not understand). So your UAC is broken

                  The restore/change of the FROM hdr is done
                  automatically for the sequential requests. What I
                  suspect in your case is an altering of the RR/Route
                  "vsf" param - check if you have the same value in the
                  outgoing INVITE (original), in the invite 200 OK (in
                  RR hdr) and the incoming ACK (in Route hdr)<br>

                      Yes, on the initial request we have the
                      uac_replace_from , but in this case the ack is not
                      supposed to reach the function , as i say before,
