18.7AT+VTS DTMF and tone generation

AT+VTS is intended to send ASCII characters or strings which cause the Mobile Switching Center (MSC) to trans- mit DTMF tones to a remote subscriber. The command can only be used during active voice calls and offers the following variants:

AT+VTS=<dtmfString> allows to send a sequence of DTMF tones with a duration defined with AT+VTD.

AT+VTS=<dtmf>[,<duration>] allows to send a single DTMF tone. In this case, the duration can be ind- vidually determined during the call.
