Thank you for your suggestion! Good idea! I was searching for more complicated solutions but mod_limit is perfect!<div><br></div><div>You say to use rate limiting but why not simply limit the calls number instead of rate?</div>

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<div>

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).<br>
In case of loop for me the solution can be simply to drop the call so my client can reroute to a different provider.<br>
There is anyone that can suggest me a way to drop looped calls?<br>
