    <p>I know the best way is the original caller handle and reply the
      183, but I HAVE to do this at OpenSIPs level.</p>
    <p>Can I use B2B_Entities and B2B_logic to do this? Is there a
      scenario to use tu parse and reply the 183?</p>
    <p>Thank you <br>

            <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>
