Steve likes these phones on Amazon:
AT&T 210M Trimline Corded Phone, 1 Handset, White (also available in Black)
No caller ID, no batteries or AC needed
$7.95 each, and available for shipping on Amazon Prime

Big Picture
It’s the fastest, easiest way to set up a phone system
Note that it only supports one-to-one; no party line, no call waiting
Does NOT need Wi-Fi infrastructure
It’s a mesh - if you’re not in direct range, put a relay node in the middle.
CAN transport broadband connections along with phone
First world usage
Remote ski village dialing between huts
Neighbor-to-neighbor during emergencies (needs emergency power)

Tech
Only dependency is power - 9-15V - think 12V battery that’s fading, fed by a simple solar panel (designed for this use case)

If you do have Internet access via Ethernet or Wi-Fi, you can use a commercial SIP system for operation on the PSTN

To Do:

  • x Figure out how to do firmware updates
  • Find a coaxial cable extension to extend antenna
  • Find a high-gain 2.4 GHz antenna
  • Measure the coaxial power jack used
  • Find a commercial off-the-shelf power cable with PowerPole connectors
  • Put together a package of off-the-shelf charger plus battery
  • Alternatively, hack a cheap UPS
  • Hack out the DC-to-AC inverter
  • Bring out the 12V
