I would try calling AT&T's NOC and asking them if they can tell what
trunk group they're receiving the call from. That might allow you to
keep tracing the call back to the previous carrier until you find the
culprit. I can send you their number privately.

You say CenturyLink was removed from route by Inteliquent and it
cleared T-Mobile so this wouldn’t seem to be a facilities issue but
have you examined the TCIC’s the calls come in on from ATT, are they
confined to a range?
There are a number of ways to get in touch with ATT but they will say
they are passing what they receive. The best be is to start with the
originating company.
At this point who would you file a FCC complaint against?

It sounds like you have done more than half the troubleshooting
already.
I would continue to work the AT&T escalation angle as it sounds they
should be the ones in a position to identify the trouble route and
resolve it.
Maybe through out the idea of a potential FCC complaint by someone in
your organization it could help move things along.
Good luck

Greetings..
Looking for the proper way to identify a third party carrier..
We have had a monthlong ongoing issue with external calls into our
switch with terrible quality. It’s random, but it’s calls to
ported numbers into one of our CLEC areas. When an affected call
comes in, it is reported as static or delay. We have obtained an
audio capture of a couple of these calls from the ingress point of
our TDM network, and the audio is severely delayed and choppy as if
it was delayed within an IP network. We’re assuming the call has
been routed through an IP low-cost carrier somewhere. (Working with
T-Mobile below, we found that their switches would route calls that
originates and terminates locally in South Carolina through
Washington state carriers.)
All of the calls with an issue come into us from a legacy ATT
tandem, but not all of the calls from the ATT tandem are affected.
We’ve been trying to get in touch with ATT for a month, and have
recently spoken to some people with no resolution. We continue to
call them daily. We worked with T-Mobile on issues with their
wireless customers calling our CLEC customers experiencing this
problem. The guys at T-Mobile were excellent to work with. (They
reached out to their 3rd party carrier Inteloquent who had rerouted
calls away from CenturyLink, which resolved calls from T-Mobile
devices.) We’re getting dozens of trouble calls a day from several
of our CLEC customers on calls originating from many other sources
(Verizon, local ILEC landlines, etc.). We’ve explained to our
customer that the trouble is not ours, that we’re doing our best
to track down the problem carrier, but we’re been notified by our
customers that we’re going to lose them, regardless.
Our last idea is to file a complaint with the FCC, but that’s
leaving issues unresolved. My questions to the community are:
* What’s the most effective way to zero in on the problem
carrier to troubleshoot the issue?
* What legal means do we have to empower somebody to support us in
finding the issue?
* What would you do if your hands were tied like ours seem to be?
* (What other questions should I be asking the community that come
to mind?)
My background is switching and some at work experience of the SS7
network. I’m of the opinion that I’m not the most qualified in
our organization to engage the FCC or twist ATT’s arm to work with
us.. but no one else beside the on-point technician is making any
effort. Internal responsibilities aside: How do we make the extra
effort to keep our customers?
I appreciate the time you took from your day reading this.
