EHS6 voice call in Linux | Telit Cinterion IoT Developer Community

We are using EHS6 development kit (”Gemalto M2M Concept Board”) and we are connected board to our Linux device via USB. Linux creates seven ports for board (/dev/ttyACM0-/dev/ttyACM6)
Is ther any AT command sample to create GSM voice call so digital voice data is using those /dev/ttyACM -virtual ports. So far I can create voice call and can answer to incoming call, but how can I get voice working?
commands which I have used so far is
echo -en "AT\n" > /det/ttyACM4
echo -en "ATDxxxxxxxx;\n" > /det/ttyACM4
Phone call is established OK, but there is no voice data in other /dev/ttyACM* -ports.
