In GSM, the tone duration value can be modified depending on the specific network.

If the active call is dropped in the middle of playing a DTMF tone, the following
unsolicited message transfers to TE: +VTS: "Call termination stopped DTMF tones
transmission".

The following table shows the +VTS parameters.

The duration defined by +VTS is specific to the DTMF string in this command only. It 
does not erase the duration defined by the +VTD command, and is erased when the G24-L 
is powered down.

If <duration> is not defined, the +VTD value is used.

The Set command sets the tone and
