      the original caller (which generate the received INVITE) and let

          <br>
          This is the scenario.<br>
          <br>
          OpenSIPs receive a INVITE and send it to a server that reply
          with a 302 <br>
          message (always)<br>
          <br>
          Then OpenSIPs, in the failure route, take the user part
          present in the <br>
          302 contact header, change the destination IP and send with
          t_relay<br>
          <br>
          The destination reply with a 183 with Require: 100rel header
          so OpenSIPs <br>
          have to reply with a PRACK. This is my problem.<br>
          <br>
          I don't know which is the best way to handle this (the PRACK)<br>
          <br>
          Thank you<br>
