Muting or Sending Key Tones

These options allow you to turn the key tones off or on. If the
Mute Keys option is selected, your phone does not transmit
the DTMF (Dual Tone Multi-Frequency) tones of the keys,
which allows you to press keys without hearing annoying key
tones during a call.
Note:
To communicate with answering machines or computerized
telephone systems, the Send Keys option must be selected.

service.
