<b><strong>procedure GoDisc;</strong><br>
</b>It sends <a href="#VocDisc">VocDisc</a> to the modem and, after that, it sends ATH0,

<p><strong><b><b><a name="Play">Play</a><br>
</b></b></strong>It plays the file, whose name is filename, NumRep times.<br>
<b><strong>procedure Play(filename : string; <a name="NumRep">NumRep</a> : Integer) ;<br>
</strong></b>if TMsgVoc is in TX status, it will play filename, NumRep times. Be sure to
set filename to a proper file because no control or automatic setting will take place
inside TMsgVoc. For example, if you set it using the name of a text file, it will be sent
to the modem all the same and an odd noise will come out from the modem. Besides, take
care the file is in the correct format, like GSM, ADPCM and so on. To see the formats that
your modem can play and record give the command AT#VSM=? Play can be called asynchronously
or driven by the event OnConn When playing is finished, the event OnPlayed will be raised.<br>

</strong></a></b>It is raised when the modem goes into 'VoiceCommand Mode', i.e. a
listener answered, so that TMsgVoc can play, record or simply receive DTMF keys.<br>
When a "voice modem" originates a call, it sends a VCON when it detects no more
"ring back", supposing the remote listener has answered going off hook. See also
the commands AT#VRA and AT#VRN which should be placed in the ConnString string. If the
determination of the end of ring back is doubtful, it is better to place an A at the end
of the string ConnString, so that the event OnConn is originated immediately. This event
can be used to start playing of a file with the method Play. <br>
