It seems strange that landline phone Phone calls to the traditional copper line would be going through a cell phone tower. I could see it with VOIP.

I know a couple guys who work for telcos and service lines and towers and such(not around TV). The landlines don't go through towers, but since they have backup capacity(Batteries and gensets) at certain "main" towers, they've trunked the POTS lines over there instead of maintaining separate battery banks. It all depends on where really.
The only reason I know this is because I got into a conversation with a buddy who works in the field about the reliability of POTS and he informed me that the POTS lines often terminate at a neighborhood level CO and are translated onto Fiber to get digitally switched. This does not mean they don't have an old copper connection from everywhere to everywhere else(which is somewhat mandated by the government) it's just that those lines are DARK most places and in a disaster, no one is going to bother energizing them either.
Your POTS line will work until the batteries and gensets run down. Then nothing is going to work.
If you live very rural, the POTS lines are the old lines and probably haven't been updated, but we're talking about TV here.
