Q3100110 - Can I play a sound file on my modem using ActiveXperts Serial Port Component?

Yes, as long as your modem supports a voice command set. It is easy to find out if your modem supports voice or not: issue the 'AT+FCLASS=?'. A modem supporting voice will respond with a list of numbers that includes the number 8.

To enter voice mode, issue the following command: 'AT+FCLASS=8' (or 'AT#CLS=8'). In voice mode, you can answer voice calls, playback sound files and record audio.

For a complete list of voice modems commands, check your modem manual.
