If the user does not own it, someone does and the accounting should play out accordingly.
I remember reading that, back in the 50s or 60s, the phone company owned "your" phone. It was permanently attached to the wall, and you weren't allowed to do anything to alter it. Did AT&T pay taxes on those phones as inventory?
That's a bit hyperbolic. It was just hung on the wall. If it was permanent, they wouldn't be able to take it back. Thanks for the reminder that we're to the point in time that "kids today" honestly have no memory of land line phones.
But yes, the phones were only available from Ma Bell, and you did have a monthly fee for them. They did have table top versions as well, so it wasn't just wall mounts. They were heavy solid well built devices. Once it was opened for anyone to make, they became cheap light weight plastic pieces of crap.
I had a landline when I was a kid, but my parents got rid of it shortly after I left for college.
