                          Yes, TH is the only thing you can do about
                          this. But as a lighter approach to B2B, I
                          suggest the TH support based on dialog module:<br>

        <div>I'm having a problem with a specific client. It ignores
          Record-route and Via fields order and send a BYE to last
          destination, not the first one. This clearly breaks RFC and
          there's no way to solve this with his bug software.</div>
        <div>

        </div>
        <div>To solve this, I was planning to implement a B2B scenario
          to it, so I'll hide the topology and the "last destination"
          will be only me.</div>
        <div>

        </div>
        <div>What do you guys think about this? Is this a viable
          solution? Is there any other better solution? I don't wanna
          put an Asterisk to isolate it.</div>
        <div>

        <div>Thanks</div>
