<p class="MsoNormal">Yes, our configuration calls do_routing multiple times for different failover cases. You may want to verify this but I believe that the additional calls will append to the relevant AVPs used by the module, so if you haven’t routed to all
destinations, you may need to clear out the AVPs prior to calling it again. I’m not positive on that part though; it may overwrite existing values.<o:p></o:p></p>
