[VoIP] Ernest Telecomm 7D-3 Payphone

[Donald Froula]

I picked up an Ernest Telecomm 7D-3 single-slot COCOT
payphone today. There is a programming switch on the
board in the phone that seems to put the keypad in
programming mode, but I get no voice prompts or any
other indication, other than DTMF when I press the
keys.

The board is labeled "Ernest D3". 

Does anyone have programming instructions for this
beast?

Thanks,

Don
