Hearing DTMF tones during call initiation (dialing) is enabled only for some tone schemes (due to each country's ISDN standardization). However, some customers asked to be able to disable these tones when in speaker mode, for privacy reasons. You can disable them by turning this setting to off. Please note that this setting has no effect on handset/headset mode.
Here is the list of the tone schemes this feature will affect:
| Note: During a call the DTMF echo is always audible, if you want to remove the tones you shout set the dtmf_volume to 0. Note: The 8xx series plays no DTMF tones in handsfree mode when a number is dialed. |
