[VoiceOps] AT&T Wireless / FirstNet routing issue contact

[Mary Lou Carey]

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. .
