A dial-tone is played when the device is in dial preparation phase:

  • Pick-up handset
  • Press Hands-free key
  • Put call on-hold

If users are using a headset, an option to not play a dial-tone is often preferred. When a call is put on-hold so the user can search something or a number, the headset will play the dial-tone and this is not user friendly.

From software 3.17, we offer the option to disable the dial-tone.

In the web-interface go to: SETTINGS - Telephony - Call Settings - Tone Selection - Dial-tone


ParameterDescription
Telephony.DialTone.Enabled

1 (Default) = Dial-tone is enabled (Yes)
