			Chapter 3 – Voice Commands
Command: +VRN	Ringback Never Appeared Timer
Description:	This command sets the length of time the modem will wait between ringbacks during call
	origination before the modem can assume that the remote station has gone off-hook.
	Syntax: +VRN=<interval>
Values:	<interval>	Decimal number specifying the time period, in units of 1.0 second, that the
		modem will wait for Ringback during call origination.
		A value of 0 forces the modem to report the OK result code immediately
		after dialing.
		The range is 1 to 25 seconds for <interval> = 1 to 25.
Default:	Interval of 10 (10 seconds)
Result Codes:	OK <interval> = 0-25
	ERROR Otherwise, or if not in Voice Mode.
Report Commands:	+VRN?	Reports current of selected values.
	+VRN=?	Reports supported range of parameter values.
Command: +VSD	Silence Detection (Quiet and Silence)
Description:	This command causes the modem to set the silence detection sensitivity and the required
	period of silence before the modem reports silence detected at the end of a voice receive
	either with the “Presumed End of Message” (QUIT) or “Presumed Hangup (SILENCE)
	event reports.
	Syntax: +VSD=<sds>,<sdi>
Values:	<sds>	Decimal number corresponding to the selected parameter.
		0	Use +VSM silence compression setting and algorithm for long-term
			silence detection (if +VSM is in use) or proprietary silence
			compression setting and algorithm for long-term silence detection (if
			+VSM is not in use).
		127 Sets less aggressive long-term silence detection independent of
			presence or use of silence compression.
		128 Sets nominal long-term silence detection independent of presence or
			use of silence compression.
		129 Sets more aggressive long-term silence detection independent of
			presence or use of silence compression.
	<sdi>	Decimal number specifying the required period of silence, in units of 0.1
		second, before the modem can report silence detected at the end of a voice
		receive either with the “Presumed End of Message” (QUIT) or “Presumed
		Hang up (SILENCE) event reports.
		A value of 0 disables the modem silence detection.
Defaults:	0,50	The range is 0.1 to 25.5 seconds for <sdi> = 1 to 255.

Report Commands:	+VSD?	Reports current of selected values.
	+VSD=?	Reports supported range of parameter values.
Command: +VSM	Compression Method Selection
Description:	This command causes the modem to set the voice compression method, the silence
	compression sensitivity, and the voice sampling rate.
	Syntax: +VSM=<cml><vsr><sds><sel>
Values:	<cml>	Decimal number identifying the compression method.
	<vsr>	<range of values> containing the supported range of voice samples per
		second of the analog signal.
	<sds>	<range of values> containing the supported range of sensitivity settings for
		voice receives.
	<sel>	<range of values> containing the supported range of expansion values for
Defaults:	1,8000,0,0	voice transmits.

Report Commands:	+VSM?	Reports current of selected values.
	+VSM=?	Reports supported range of parameter values.
