If anyone else is having problems with AT&T Wireless calls failing when
they terminate on the SS7 network, I know what the problem is. I've
already helped two companies get their problems fixed and would be happy
to share my contacts with anyone else who needs it. The more people that
complain, the quicker it will get fixed.
I made sure the FCC knows about this problem and that it involves
multiple RBOCs and ILECs, as well as LATAs. That way they can see how
widespread this issue is. So if you think your call failure issues with
AT&T Wireless are related to the SS7 work in any way, please contact me
at the number below and I will gladly pass along my contacts for AT&T
Wireless to you. I will also add your company's name to the FCC list of
carriers that have been experiencing call failure issues on AT&T
Mobliity'snetwork. .

Collin,
It appears to me that AT&T wireless attempted to fix your problem
today. Apparently it didn't go well. Congrats on bringing down their
network!

Well the email is for an STP group of some sort, they can’t create
a ticket, but were able to tell me when calls started failing, and
that Frontier needs to open a ticket with ATT Mobility since they
are directly connected.
Haven’t been able to convince Frontier to do anything, as they
claim AT&T is routing the calls incorrectly to them on the wrong
group (AT&T STP folks say the TCICs changed at the time the calls
started failing).
Have engaged PSC for assistance, still have been unable to get
anyone at ATT to actually accept a ticket from me. We have hundreds
of customers complaining, and we have been steering them to ATT.
Many of them are being told it’s not their problem. Others are
being told the “local site is degraded” and they are working on
it.
Appreciate any help anyone can provide!

Well that was phone number was a maze. I managed to get an email
address out of somebody dl-ss7trctier2_at_att.com, but nobody could
open a ticket.
Going to give the email address a try.

We appear to have an issue with AT&T Wireless failing to complete
calls to us and anything behind the local Frontier tandem (which
they
apparently were routing our calls to). We are seeing call failures
on
testing from an AT&T wireless cellular phone to both our numbers,
and
the Frontier exchanges served off the tandem. Any one got any
contacts
to open a ticket? Our end-user ticket, and our FirstNet ticket
through
the local 911 center have both been unsuccessful, and we are going
on
72 hours of inability to receive calls from AT&T Wireless
customers.
Thanks,
