	This may be due to the way which Touch Tone (TT) is enabled or
disable by your local RBOC.
If you have a non TT line your TIP & RING lines may be '+' and '-'
respectably. When you request TT they reverse the polarity and then
your TT AT&T phones will dial. Some new phones, and most modems ignore
the line polarity. One company put out a device that replaces the mouth
piece on a standard phone, with a TT keypad.
I heard Pacfic Telesis (PT&T) used to just add TT charges to your bill,
but I doubt they will try that again, after all the flack they got for 
signing people up for call waiting and other junk without asking them
first.
	I wonder if using a TT phone, on a non TT line is toll fraud?
	Brad.
