DTMF Tone Dialling

The tones produced by your phone when you press the keys
are known as Dual Tone Multi Frequency tones, or DTMF tones
for short.
Some possible uses of the DTMF tones are to:
• Get messages from answering machines.
• Signal pagers.
• Control tone operated voice/mail systems.
Your phone will produce DTMF tones when you press the
following keys:
0, 1,... ..., 8, 9, * or #
When you press these keys during a phone call, the DTMF
tones will be produced and the display will show the keys
pressed.
In addition to showing the keys pressed, the display will also
show Call?. This message will be removed, three seconds
after the last key press.
If you press O at this point, your phone will place the
current call on hold and attempt to call the number entered.
