The response is: 0-255 OK with between each line. AT+VRX This command causes the DCE to start the voice reception process. The DCE begins the voice receive mode by returning the CONNECT result code to the DTE. After this report, the DCE sends shielded voice data to the DTE.

AT+VSD=, This command causes the DCE to set the silence detection sensitivity and the required period of silence before the DCE can report silence detected either with the QUIET or SILENCE shielded code. See the description of the shielded code for the difference between the SILENCE and QUIET report. The range of the sensitivity is from 0 to 31. The higher the value, the higher the sensitivity threshold level. The magnitude difference in sensitivity level has a unit of dB. = 0 means silence detection is disabled or not supported.

OK:
The DCE issues this result code if DCE accepts this command.
ERROR:
The DCE issues this result code if <value> is out of range.
AT+VRN?
DCE will return current Ringback Never Appeared Timer, followed by the OK result code.
AT+VRN=?
DCE will return permitted interval of Ringback Never Appeared Timer.
The response is:
0-255
OK
with <CR><LF> between each line.
AT+VRX
This command causes the DCE to start the voice reception process.
The DCE begins the voice receive mode by returning the CONNECT result code to the
DTE. After this report, the DCE sends <DLE> shielded voice data to the DTE.
The DTE can abort the voice receive state by sending a character other than <XON> and
<XOFF>. On termination of the voice receive state, the DCE will append a <DLE><ETX>
character pair, followed by the VCON result code.
AT+VSD=<sds>,<sdi>
This command causes the DCE to set the silence detection sensitivity and the required
period of silence before the DCE can report silence detected either with the QUIET or SILENCE
<DLE> shielded code.
See the description of the <DLE> shielded code for the difference between the SILENCE
and QUIET report.
The range of the sensitivity <sds> is from 0 to 31. The higher the value, the higher the
sensitivity threshold level. The magnitude difference in sensitivity level has a unit of dB. <sds> =
0 means silence detection is disabled or not supported. The range of the interval <sdi> is from 0
to 255 in units of 0.1 second.
Result codes:
OK:
The DCE issues this result code if DCE accepts this command.
ERROR:
The DCE issues this result code if the <sds> or <sdi> is out of range.
AT+VSD?
This command causes the DCE to report current <sds> and <sdi> settings. The form of the
response is:
<sds>,<sdi>
