The Field Phone project is your own personal telephone company! This project allows you to use normal wired telephones for communication within and between buildings and shelters, either for everyday convenience or for security in a crisis when the normal telephone system might not be available.

    - Communication between off-the-shelf wired telephones.
    - Operation from external 6v to 30v power.
    - Charging and operation from a lithium iron phosphate (LiFePO4) battery.
    - Provision of discreet ring signaling to remote phones (optional ring interface modules required at remotes)
    - Ability to operate two distinct call networks, or to bridge these together into a single network.
