      <blockquote><font face="Monaco, Courier New"><span
            style="font-size:11pt"> &nbsp;&nbsp;Hello,<br>
            &nbsp;<br>
            &nbsp;I have a scenario where FS routes hundreds of calls and
            loop detection is needed. Adding to that, I can't rely on
            hop counter being decremented by other network elements. I
            can use limit in the following fashion:<br>
            &nbsp;<br>
            &nbsp;&lt;action application="limit" data="hash loop_test
            ${caller_id_number}${destination_number} 10
            !NORMAL_CIRCUIT_CONGESTION"/&gt;<br>
            &nbsp;<br>
            &nbsp;So, whenever I have 10 calls with the same calling and
            called party number combination, limit will kick-in and
            break the loop.<br>
            &nbsp;<br>
            &nbsp;<b>Question</b>: Is this efficient from the perspective of
            how "limit" and hash back-end work? Once I have a few
            thousand calls, all having unique "resource" will this
            become resource hungry?<br>
            &nbsp;My main concern is that it will create hundreds of hash
            entries all having the same realm but unique resource.<br>
            &nbsp;<br>
            &nbsp;Anyone knows a better solution?<br>
            &nbsp;<br>
            &nbsp;Thank you,<br>
            &nbsp;Victor<br>
