txt.att.net outage?

This may be the issue

Here are some details on this Government protocol implemented by all Telecom Carriers.

Why it is being done? To support FCC mandate for STIR/SHAKEN, an industry set of rules designed to authenticate and validate CallerID information associated with phone calls using digital signatures.

SHAKEN/STIR is a framework of interconnected standards. SHAKEN/STIR are acronyms for Signature-based Handling of Asserted Information Using tokens (SHAKEN) and the Secure Telephone Identity Revisited (STIR) standards.

What is the benefit to the clients being impacted (what do they get as a result)? Provide a means to mitigate/eliminate illegally spoofed calls from RoboCallers.

FWIW, AT&T does not suggest using the txt.att.net<http://txt.att.net> email for anything critical. In a previous role I handled public safety CAD, and AT&T (and Verizon, if I remember correctly) made it very clear that if you want to be able to send anything other than a miniscule volume of texts through the email-to-SMS gateway, you would need to pay for their enterprise messaging service.

If the public safety agency/agencies in question subscribe to the FirstNet service, they should be able to reach out to their principal consultant (account team) and get a good resolution.

Know this is a longshot, any chance anyone from the txt.att.net<http://txt.att.net> domain might be able to help us with what we believe is a blacklist block or possibly an outage?

We deal with 911 cad dispatching and is affecting first responders so looking to see if there is a faster way to resolution.

Thanks, in advance.
