    <tt>Hi Br<tt>ian,<br>
        <br>
        <tt>In this case, I guess <tt>that the OPen<tt>SIPS B2B
              (handling the <tt>REFER<tt>) should sit b<tt>etween the
                    OpenSI<tt>PS LB and Asteri<tt>sk - again , this is
                        the case only if the <tt>result of the tra<tt>nsfer
                            is a call to an <tt>Aster<tt>isk bo<tt>x
                                  too. If the call may be re<tt>directed
                                    back to a carrier, the OpenSIPS B2B
                                    should sit in f<tt>ron<tt>t of the
                                        LB.</tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt></tt><br>
