A better way to do this is limit this during a period of time, say 5 per second, when calls loop they tend to loop up very quickly

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