Not to hijack the thread, but we are talking about weird things you can do with ATAs here: anyone know of an ATA with a cell modem? I’m responsible for a municipal septic pump with an autodialer in the control station for alarms. It would be nice to get a phone call from it if it fails.

Yes, cellular modems with RJ11 phone ports do exist. From memory, the ZTE MF275 and the MF288 were such units (both are discontinued, though). You could receive phone calls through it. Technically speaking, it is an "ATA", but you can't control the FXS port, as it's directly linked to the number associated with the SIM card. Another solution would be using a cellular router in conjunction with a "normal" manageable ATA, which lets you configure the FXS port with a remote SIP account. I think you can even find some stuff on ebay/aliexpress that combines both functionalities, but I never tried them (and would be worried of lack of support or firmware updates).

I commonly do work in this space, and my solution is a standard ATA hooked up to a Peplink device for cellular connectivity. My experience has been that 'serving' over a cellular connection is dicey, and I've abandoned my quest to get static IPs on all of my cellular gateways. Peplink has a management portal that lets me control everything, including a built-in system to connect to web management portals behind the gateway. PRI/T1 technology based on copper wires is being discontinued in much of the US right now, and consequently, demand for this kind of solution is going up

I think Polycom, since bought by HP, might have something like that. For wireless backup of a small LAN setup you can examine Cradlepoint.
