The other issue is how totally useless California has discovered cell phones can be in emergencies like wildfires. In Santa Rosa, the entire cellular system was down because towers had all burned up in the first few hours of the fire and it took days to get temporary portable cell sites set up. It appears that all Roadside Emergency Phones installed since 2015 are solar powered satellite phones to avoid that problem. Of course, in Santa Rosa's case, landlines were not impacted. They were all underground and the phone company system was able to generate power to keep them operating. We got a plea from the hospitals in Santa Rosa to put out the word to their employees checking in to not call their supervisors cell phone numbers, as they were down....but to call the landlines numbers in the hospital.Looks like they are going the way of the pay phone as well.

Decline in usage
In California, freeway callboxes were used about 98,000 times in 2001. That number dropped by 80 percent to 19,600 times in 2010, or about 1 call per box per month. The cost of callboxes for the Service Authority for Freeways and Expressways (SAFE) program in the San Francisco Bay area is $1.7 million annually. As a result, since 2009 approximately half of the callboxes have been removed from certain California highways, preferentially leaving them only in places where cell phone coverage is poor.
Florida previously had callboxes installed at one-mile intervals along all its Interstate Highways as well as Florida's Turnpike. These boxes were all removed by 2014 after a 65-percent decrease in usage over an eight-year period, in line with increased mobile phone usage. The boxes were costing the state roughly $1 million per year to keep operational.
That reminds me of roads that used to have periodic call boxes.
I can't remember the last time I saw a highway with call boxes. I wonder if those still exist anywhere? I-185 here in Georgia had them, but I have not been on that interstate in years.

Landline phones get their power from the phone company (through the phone line).landlines don't require electricity from any source to operate though most folks that still have them tend to have cordless phones which do NOT work absent electricity. I've still got an old corded phone I used to plug in when the power went out before we got our whole house generator. my brother had to hunt one down when he was pre generator purchase and his area in northern california lost not only their regular power but also their cell phone access when pg&e included the cell towers in that region's rolling blackouts.

-48 volts DC when all the phones are on hook and 100 Volts RMS @ 20 Hz to make the phone ring.thank you for the clarification.
As I recall, you didn't get a dial tone until you put money in.
Technically, most landline central offices run off battery all the time. It's just a question of how the batteries are recharged. Shore power or generator. The central office I toured had a huge room of batteries. They could run the phone system for 24 hours if the shore power was down and the generator failed.-48 volts DC when all the phones are on hook and 100 Volts RMS @ 20 Hz to make the phone ring.
It’s also why in a hurricane Verizon and AT&T wireless will often have service and T-Mobile will not.
The practice of having generator backup is more part of Verizon and AT&T’s history as a traditional phone company than the company’s that sprang into existence as a wireless carrier.
