Tone/Pulse Dialing
With some older Central Offices, you may have to make calls on CO lines that are
programmed for rotary dial pulses. This feature enables you, while on these lines, to
switch to tone dial in order to access remote equipment (such as an answering
machine) requiring DTMF tones.
With ISDN calls, when 7RQH'LDO6HOHFW is pressed, all of the digits entered after
that point will be sent with DTMF tones.
