<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-family: "Arial","sans-serif"; color: black;">we're interested in trying to track down the source of the calls
and where they are entering the PSTN network. <br>
<br>
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.<br>

<p class="MsoNormal"><span style="font-family: "Arial","sans-serif"; color: black;">Just
curious. How are you having issues tracking the trunks(virtual or real) that it
is coming from?<br>

<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-family: "Arial","sans-serif"; color: gray;">I have a question to pose. If it's not appropriate, please
let me know.<br>
<br>
My switches are currently taking in a large amount of traffic from one
particular number destine for multiple terminating numbers across my CLEC
users.<br>
<br>
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.<br>
<br>
<br>
Originating number is 3074591039. <br>
<br>
<br>
<br>
The originating introductory messages appear sculpted and carry no originating
info.<br>
<br>
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.<br>
