[VoiceOps] Switches being flooded by unwanted calls

[cololiberty at comcast.net]

Unfortunately, I've never had luck with doing that. Mostly because the preceding carriers do not want to disclose their network connections due to proprietary information. 

Even with carriers you have good relations with, eventually you get stonewalled. I've only been able to go back 1 hop

Perhaps this is a really dumb question – why not work with whoever operates the other side of the trunk and have them trace it back, and repeat until you’re back at the source?

we're interested in trying to track down the source of the calls and where they are entering the PSTN network. 

We have no problems seeing the trunks where it is handed off to us. especially due to the large amounts of traffic we are seeing from it.

Just curious. How are you having issues tracking the trunks(virtual or real) that it is coming from?

I have a question to pose. If it's not appropriate, please let me know. 

My switches are currently taking in a large amount of traffic from one particular number destine for multiple terminating numbers across my CLEC users. 

We're having trouble tracking it down. It's coming into us via SIP and SS7 and I was wondering if anyone else was seeing anything with it as well. We have already confirmed a few other carriers seeing it as well. 


Originating number is 3074591039. 



The originating introductory messages appear sculpted and carry no originating info. 

Internet searches on this number brings up allot of people being bothered by this, chances may be good others out here my have users affected as well.
