    <div><tt>Hi, Seth!<br>
        <br>
        So basically you want to change the outgoing interface for the
        second leg of the call, right? Instead of record_route_preset()
        function, have you considered using the force_send_socket()
        function? This forces OpenSIPS to switch the interfaces and
        should change the VIA headers properly without any issues. Let
        me know your answer.<br>
        <br>
        Best regards,<br>

          <div>
            I am running OpenSIPS 1.9.2 and I am using the load_balancer
            module to balance outbound calls.  Some of my gateways are
            on LAN and some of them are external to my network.  There
            is NATing involved and I am using set_advertised_address to
            ensure Via headers are properly constructed for the INVITE
            and I am also using record_route_preset to ensure the
            Record-Route headers are correct.  I am also using mhomed=1.
             Now to the problem.</div>
          <div><br>
          </div>
          <div>Let&#39;s say during call setup the first gateway chosen is
            on the LAN.  If this call setup fails it hits the failure
            route and another destination is chosen.  It also sends an
            ACK to the first destination to let it know we received the
            negative response and the ACK contains the correct IP
            address in the Via header.  Now, when the second gateway
            that&#39;s chosen is external and that call setup also fails,
            the ACK that is returned to the second gateway for the
            negative response still contains the local LAN address in
            the Via headers even though the INVITE to the second gateway
            had the correct IP Address in the Via.  In fact, every other
            gateway chosen after that will ACK with the local LAN
            address.  I&#39;ve tried everything I can think of to try and
            change this IP address, but I can&#39;t seem to do it.  I would
            really appreciate someone&#39;s insight into this.</div>
