[cisco-voip] School Building VoIP 911

[Justin Steinberg]

you can buy an ATT 808A emergency transfer panel on ebay for less than 50
bucks and it will provide emergency phone service for up to 5 lines.   when
the 808a has power it connects the CO to the FXO port and the FXS port to
the analog phone.  When the 808 loses power, it connects the CO directly to
the analog phone providing CO dialtone.
