Command

Description

RING

DCE reports ringing from remote station.

AT+FCLASS=8

The modem enters voice mode.

OK

DCE responds.

AT+VGT=128

Set speaker volume to normal.

<DLE>-R

DCE detects another ring, and notifies DTE.

AT+VLS=1

The modem answers call.

OK

DCE is off-hook

The TAD next plays its greeting message, issues a beep, and records the caller's message.

The Application may transmit voice samples using the wave driver. The application may issue WAVE_OUT_OPEN and WAVE_OUT_WRITE messages to the wave driver.

At the end of the greeting message the application may issue the WAVE_OUT_STOP message to the wave driver.

AT+VTS=[933,0,120]

DTE annotates greeting message with a 1.2 second beep.

OK

DCE responds.

The Application may receive voice samples using the wave driver. The application may issue WAVE_IN_OPEN and WAVE_IN_START messages to the wave driver.

AT+VSD=128,50

DTE selects normal silence detection sensitivity and a silence detection interval

of

5 seconds. Enable silence detection.

 

OK

DCE responds.

AT+VLS=5

Speaker is attached to system, and modem is off-hook.

OK

DCE is off-hook

The caller leaves a message, and hangs up. The modem detects silence for a specified period of time, and then notifies the DTE.

<DLE>-s

DCE issues presumed end of message after silence detection interval has

 

elapsed.

At the end of the message the application may issue the WAVE_IN_STOP message to the wave driver.

ATH
