        Thanks a lot Bogdan.<br>
        <br>
        Is it possible to use another ds_select_dst in the failure_route
        to redistribute failed node's calls to remaining Active nodes?
        Even if I can do that, it has to be in the probing_mode=0, am I
        right? I assume I can't "catch" the failure and manually adjust
        the destination in probing_mode=1.<br>
      </div>

    no, you cannot do that as ds_select_xxx() is all the time done over
    the original set (like all destinations are active). So you cannot
    do a dispatching only over the active ones - dispatcher will compute
    the hash, it will identify the corresponding destination and, if
    failed, it will shift to the next one.<br>

          Hi Matt,<br>
          <br>
          If Asterisk 4 is down, the hash will not be recalculated, but
          the calls that should go to Asterisk 4 will simply be pushed
          to the next available entry in the dispatcher list.<br>
          <br>

            <div dir="ltr"> I'm new to dispatcher - wanted to clarify
              couple of things...<br>
              <br>
              <br>
              <br>
              I'm using algorithm 7 (hash over the content of PVs
              string) to pick a destination.<br>
              <br>
              <br>
              modparam("dispatcher", "hash_pvar", "$pvar")<br>
              ds_select_dst("1", "7");<br>
              <br>
              <br>
              Let's say the probing_mode is 1, and based on the value of
              $pvar&nbsp; (A, B, C, etc.), incoming requests are dispatched
              in the following fashion:<br>
              <br>
              <br>
              A -&gt; Asterisk1<br>
              B -&gt; Asterisk1<br>
              C -&gt; Asterisk2<br>
              D -&gt; Asterisk3<br>
              E -&gt; Asterisk4<br>
              F -&gt; Asterisk4<br>
              <br>
              <br>
              What happens to E, F if Asterisk4 fails? Are they
              distributed among the remaining servers or do they all go
              to the same server? <br>
              <br>
              Do A, B, C, D still go to the same servers? In other
              words, is the hash recalculated?<br>
              <br>
              <br>
              Can hash_pvar be changed; e.g. use $si for route[1], use
              $ci for failure_route[1]?<br>
              <br>
              <br>
              Thanks,<br>
