Voice Initialize All Parameters
This command causes the modem to initialize all voice parameters to their default values.
Syntax: +VIP
None
OK
ERROR If not in Voice Mode.
Start Modem Receive (Record)
This command causes the modem to start the voice reception process.
Syntax: +VRX
None
OK
ERROR If not in Voice Mode.
Send Voice Tone(s)
This command causes the modem to send DTMF digit or hookflash tones with the
duration specified by +VTD, to send DTMF digit or hookflash tones with duration specified
by +VTS, or to send single or dual tone frequencies with duration specified by +VTS.
Syntax: +VTS=<string>
See the highlighted text for a discussion of defaults.
<string>
The tone generation consists of elements in a list where each element is
separated by a comma. Each element can be:
•
•
•
Missing subparameters assume the default value. Unspecified values
always default to zero for frequencies, DTMF * for DTMF tones, and
+VTD for duration. The omission of commas (and associated
subparameters) is valid.
The quantity in the square brackets consists of a 3-element list
(freq1,freq2,dur), which can be used to send single or dual tones.
•
•
•
A list may contain null elements. For example, [3000] means that the DCE
generates a single tone at 3000 Hz for the default duration, [3000,3300]
means that the DCE generates a dual tone at 3000 and 3300 Hz for
the default duration, and [,3300] means that the DCE generates a
single tone at 3300 Hz for the default duration.
The quantity in the curly braces consists of a 2-element list (X,dur), which
can be used to send DTMF tones or hookflash. The first element is the
DTMF tone or hookflash (!) character (X), and the second element is the
duration (dur) in 0.01 seconds. The characters are of the same set given
above. A list may contain null elements. For example, {2} means DTMF
tone 2 for the default duration and { } means silence for the default
duration.
The modem will stop the tone generation at the point in the string where
the modem detects a parsing error or encounters an invalid frequency
range, a <CR>, or a semicolon.
+VTS=?
A single character which the modem interprets as a DTMF digit (0 - 9,
#, *, or A-D) or hookflash (!), with a duration given by +VTD.
A 3-element string enclosed in square brackets, “[freq1,freq2,dur]”,
which the modem interprets as a general dual tone and duration
selection, or
A 2-element string enclosed in curly braces, “{X,dur}”, which the
modem interprets as a DTMF digit (0 - 9, #, *, or A-D), or hookflash (!)
with a duration (dur) different than that given by the +VTD command.
The first element is the first frequency (freq1) with range 0 or 200-3000
Hz.
The second element is the second frequency (freq2) with range 0 or
200-3000 Hz.
The third element is the duration (dur) in 0.01 second intervals with
range 0-255 (ASCII units of 10 ms).
Reports supported range of parameter values.
