[VoIP] Ernest Telecomm 7D-3 Payphone

[Jayson Smith]

Hi,

     After doing a bit of searching, I found this URL that lists lots of
parts and ordering information
 http://www.ernesttelecom.com/parts.htm
The manual costs $10. They don't seem to have much of a main website. I have
not yet found the manual available in any electronic form.
Just curious, what's it programmed like? Where'd you get it, and how much
did it cost you? Maybe you have to enter a pin code in order to program it.
In this case, there may be a default specified in the manual, or the
previous owner may have set one.
Hope this helps.
Jayson
