Yeah, that's a great idea actually, I could just concatenate some PVs to form a key like $si-$rU.<div><br><br><div class="gmail_quote">On Mon, Jun 29, 2009 at 8:53 AM, Bogdan-Andrei Iancu <span dir="ltr"><<a href="mailto:bogdan@voice-system.ro">bogdan@voice-system.ro</a>></span> wrote:<br>

<br>
This will be kind of pike but instead of using as input the source IP string, it should use a custom string you build form script, right ? this string will be a kind of key (logical one) to identify the loop.<br>

Hey All,<br>
I was wanting to submit a feature request for loop detection. Specifically NOT SIP loop detection, but when another technology / B2BUA is involved where max-forwards can't be used. This is for big loops. <br>
The idea is similar to the pike module. However, you bascically look at the to_did and the source IP and if you see more than X calls in Y period, begin to reject them for Z seconds.<br>
<br>
Simple enough. This has come up a dozen times for me and for now I have to handle it with kludge of memcache, and perl scripts to detect these issues in my cdr.<br>
<br>
The loops are a bit nuts and are always the results of someone doing something stupid (but hey, it does happen). The loops are like, my customer sends me a call to one of thier own DIDs (they've misrouted it to me) and I send it to my carrier, who sends it to the pstn, back to my customer, back to me, etc.. There may be a ss7 portion in there so it keeps looking like a new call on the SIP side. <br>
So without anything, this can clog up my call paths pretty quickly, the proposed feature would blacklist the source_ip to_did combination for a period of time to kill the loop.<br>
<br>
Thoughts?<br>
