# DoDialTones

Set `DoDialTones` to `True` to include dial tones in addition to DTMF tones, if tone detection is enabled.

There are two types of dial tone:

- Dual-Tone Multi-Frequency dial tones, used in voice-activated menus.
- Standard dial tones used in regular telephone calls.

Set `DoDialTones` to `False` to identify only Dual-Tone Multi-Frequency dial tones. Set `DoDialTones` to `True` if you want to identify both types of dial tone.

This parameter has an effect only if you have already enabled DTMF tone recognition, either by setting DoToneClass or by using the audiopreproc module mode T (see [audiopreproc] Module Configuration).
