<BR>
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>
<BR>
<action application="limit" data="hash loop_test ${caller_id_number}${destination_number} 10 !NORMAL_CIRCUIT_CONGESTION"/><BR>
<BR>
So, whenever I have 10 calls with the same calling and called party number combination, limit will kick-in and break the loop.<BR>
<BR>
<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>
My main concern is that it will create hundreds of hash entries all having the same realm but unique resource.<BR>
<BR>
Anyone knows a better solution?<BR>
<BR>
Thank you,<BR>
Victor<BR>
