5.2.2.3 +VTR - Start Voice Transmission and Reception (Voice Duplex)
This command causes the modem to start the voice transmission and reception process (Voice Duplex) without either
acoustic echo cancellation or line echo cancellation. The modem begins the Voice Duplex State by returning the CONNECT
result code to the DTE. The modem then sends <DLE> shielded voice data to the DTE, and the DTE can send <DLE>
shielded voice data to the modem. The modem will accept data from the DTE and send data to the DTE in the format
previously selected by the +VSM command, and use the flow control method selected by the +IFC command.
The modem signals termination of the voice data stream by appending a <DLE><ETX> command and padding out to an octet
boundary if needed. The modem will issue the <DLE><ETX> character pair (thereby ending the modem to DTE voice data
flow) followed by the OK result code, and return to the command mode after the modem has completely transmitted the
contents of its buffer.
There are two methods to leave the Voice Duplex State: the DTE sending a <DLE><^> shielded code or the inactivity timer
elapsing in the modem. The Voice Command State is entered upon Voice Duplex State termination.
This command will function when the input and output are from/to the same I/O device, such as local handset, line, or
mic/speaker.
Syntax
+VTR
Result Codes
OK
Upon command acceptance.
ERROR
The modem is not connected to the line and a non-line device.
