Chapter 6 – Voice Commands

AT+VLS=2	The DCE answers the phone.
OK	The DCE indicates that it is in Voice Command mode.
AT+VTX	The DTE selects Voice Transmit mode.
CONNECT	The DCE agrees.
<Data>	The DTE plays the welcome message.
<DLE> <ETX>	The DTE indicates the end of the data stream.
OK	The DCE indicates that it is in Voice Command mode.

AT+VTS= {933, 0, 12} The DTE annotates the greeting message with a 1.2 sec. beep.

OK	The DCE is ready for another Voice command.

AT+VSM=132, 7200, 0, 0 The DTE selects a low bit compression scheme to save disk space.

OK	The DCE agrees.
AT+VRX	The DTE selects the Voice Receive mode.
CONNECT	The DCE agrees.
<Data>	The DCE delivers <DLE> shielded and silence-compressed voice data across the
	DTE/DCE interface.
<DLE> <NUL>	The DTE strokes the Inactivity Timer.
<DLE> </>	The DCE reports the start of a possible DTMF tone.

<DLE> <5> <DLE> <5> The DCE reports a DTMF 5 detection for 140 milliseconds (within a 70 millisecond resolution).

<DLE> <->	The DCE reports the end of the DTMF 5 detection. For this example, DTMF 5 means
	"finish with the voice message, and switch to fax mode".
<DLE> <!>	The DTE wishes to end the record by sending an abort command.
<DLE> <ETX>	The DCE indicates the end of the Voice data stream, and returns to Voice Command
	mode.
AT+VNH=1	The DTE selects to disable automatic hang-ups while in Service Class 2 +VIT=0 (+FSK
	command result codes in Telco on-hook). The DTE switches the +FCLASS=2 DCE to
	Service Class 2 fax mode.
OK	The DCE agrees.
ATA	The DCE starts the fax receive process.
