Device - Sierra Wireless MC7304
I have installed GobiSerial and GobitNet drivers but during voice calls, the modem’s speaker isn’t showing any activity of incoming audio.
OS - Ubuntu-14.04
Modem Source : alsa_input.usb-Sierra_Wireless__Incorporated_MC7304_0123456789ABCDEF-10-MC7304.analog-mono
Modem Sink: alsa_output.usb-Sierra_Wireless__Incorporated_MC7304_0123456789ABCDEF-10-MC7304.analog-mono
Methods tried - AT commands & slqssdk API
Any ideas how to send/receive audio data of voice calls ?
