STIR/SHAKEN only affects voice calls.  It has nothing to do with SMS.

As several other people have said, if you're sending safety critical SMS 
messages, use
a real SMS service, not a carrier's courtesy low volume e-mail gateway.

SMS services are not free, but they are not expensive, typically about 1/2 cent 
per message.

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.

be able to send anything other than a miniscule volume of texts through the

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.

I think ChatGPT agrees with you:

txt.att.net is a domain owned by AT, a large American telecommunications
company. It is typically used to send and receive text messages, and it is
generally considered a reliable resource for this purpose. However, as with
any online service, it is possible for issues to arise, such as delays in
delivery or errors in sending messages. It is also worth noting that
txt.att.net is a free service, so it might not have the same level of
security or reliability as a paid service. If you have any specific
concerns or experience issues with txt.att.net, it's best to contact AT
customer service for assistance.

[Aaron de Bruyn via NANOG]

txt.att.net  is returning MX records and those machines 
don't have port 444 open...

Wouldn't you want to be sending something like a SNPP message instead? It's a 
much less convoluted delivery process and is almost real-time (no queuing).

I guess it's been a decade or so since I've dealt with emergency services and 
paging...is SNPP even a thing anymore?

I looked at some old code I wrote 
(https://github.com/darkpixel/snppsend/blob/master/more-providers 
), and it 
doesn't look like snpp.attws.net  exists.

Hi Dan,

As I understand it, txt.att.net is a low-volume courtesy service not
intended for important communications. A paid service like Twilio can
handle production-grade SMS delivery.
