• USE TOUCH TONES
Warning: If you send touch tones while in analog mode, be careful
not to send confidential information. Check your phone display for
the
icon, indicating the presence of a digital network.
Touch tones (sometimes known as DTMF tones) are those tones produced
when you press the keys on your phone keypad. You can use touch tones
for many automated dial-up services such as banking and airlines, or for
entering your voice mailbox number and password.
Touch tones are sent during an active call. You can send them manually
from your phone keypad, or send them automatically by saving them in
your phone.

You may customize the way your phone sends the touch tones for
