Voice Control
DTMF Tones Transmission +VTS
Execute command allows the transmission of DTMF tones.
Test command provides the list of supported <dtmf>s and the list of supported <duration>s in the format:
(list of supported <dtmf>s)[,(list of supported <duration>s)]
Syntax
Command Command type
AT+VTS=<dtmfstring>[,duration] Execute
AT+VTS=? Test
Parameters and Values
<dtmfstring> String of <dtmf>s; that is ASCII characters in the set (0 9), #,*,(A D),P; it allows the
user to send a sequence of DTMF tones, each of them with a duration that was
defined through +VTD command
<duration> Duration of a tone in 1/100 sec. This parameter can be specified if only one ASCII
character is used in the dtmfstring.
0 A single DTMF tone is transmitted for a duration depending on the network, no
matter what the current +VTD setting is.
1‐255 A single DTMF tone is transmitted for a time <duration> (in 10 ms multiples), no
matter what the current +VTD setting is.
Notes
„
This command operates in voice mode only. See +FCLASS.
„
The character P does not correspond to any DTMF tone, but it is interpreted as a pause of 3 seconds between
the preceding and succeeding DTMF string elements.
