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.
