EHS6 voice call in Linux | Thales IoT Developer Community

November 9, 2016 - 1:55pm, 3555 views

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.
