Self contained IP phone ready to go.

Everything in one box

 

Connected and powered.

 

Ready for action.

 

Bit rough but it works. Hiding under the cover is a 20AH battery and two regulators, One set at 5V for the phone the other set at 8V for the router. The anderson plug top left marked battery charge port is directly connected to the battery for charging and can also run other 12V accessories. The second anderson plug can be used to power the phone/router from an external supply (9V to 30V). Of cause the switch selects power from the internal battery or the external supply.
