Ok, so a line like:
<action application="limit" data="hash inbound ${destination_number} 1/5 !NORMAL_CIRCUIT_CONGESTION" />
avoid loops because Freeswitch doesn't accept more than 1 call each 5 seconds (the loops are very fast) but allow to have concurrent calls to the same destination number.
Thank you Ken!

Well you could do that, but lets say you have a client that sends you several calls to a conf number... Also when you loop calls they usually loop fairly fast, by using a rate limit based on the ani and dnis you can still let additional calls pass while reducing the chances of getting loop due to call_id rewrites that are happening at the b2buas that are causing the loop
KThank you for your suggestion! Good idea! I was searching for more complicated solutions but mod_limit is perfect!
You say to use rate limiting but why not simply limit the calls number instead of rate?
For example a row in dialplan as:
<action application="limit" data="hash inbound ${destination_number} 1" />
can avoid loops?

I hate this problem... Mod_limit matching ani+dnis doing rate limiting (say 5 calls with matchig ani+dnis in 2 seconds) can kill the loop and either allow you to re-route or allow then to re-route... This happens a lot more than you thing between 2nd and 3rd tier aggregators
In some situation there are calls that loops among some providers and I want avoid that situation.
For example, I receive the call from my client A, I send this call to my provider B but for some reason the call return to me (for example because B sends the call to A and A resends the call to me).
In case of loop for me the solution can be simply to drop the call so my client can reroute to a different provider.
There is anyone that can suggest me a way to drop looped calls?
