Description:
This specific command allows a DTMF tone to be played on the current speaker. DTMF, volume and

network, use the +VTS command.
Values:

<dtmf>
This parameter sets the DTMF to play in {0-9,*,#,A,B,C,D} (mandatory if
<mode>=1)
<volume> (0-3)
This parameter sets tone gain. The values are identical to those of the +WTONE
(speaker) command (mandatory if <mode>=1).
<duration> (0-50)
This parameter sets the tone duration (unit of 100 ms). When this parameter is 0
(default value), the duration is infinite, and the DTMF tone can be stopped by
AT+WDTMF=0.
