One of the upgrade paths mentioned when classic ADSL shuts down is Fusion service. How do I tell it Fusion actually -is- available to me (wire center ALMDCA11 switch ALMDCA11DS0, maybe 10k feet with a great S/N)? At one time, it was offered for my location but the tools seem to push towards what I think is AT&T FTTN.
Assuming that Fusion and it's static IPs really aren't available, what can Sonic provide that will get a static address or two? A GRE tunnel into the data center? A wireguard tunnel? Other options? Most of the people that still have statics are going to be the more sophisticated users and able to set up the gateways/etc. (And most of the people who didn't already migrate to Fusion probably didn't see a need to. I've been happy with my service since it was installed 10+ years ago.)
Also, if AT&T does install Sonic service, do they take out the existing POTS line? (I kind of like having something with it's own power.)
