voiceSetChannel (Function)

This function is used to select where the voice output should be routed to.

By default the voice will be routed to the GSM connection for voice/DTMF use, but it can also be routed to the xVoice output available on some devices. Please consult the technical manual for more information.

Using xVoice it is possible to play digitized voice to an external speaker.

  voiceSetChannel(ch := 1);
  // Play the "Welcome" message
  voiceTalk(message := "Welcome.wav");
  ...
END;
