title: Voice commands for Huawei GSM/UMTS usb dongles?
body: <p>I am trying to find out how to use voice functions with a HUAWEI E173 dongle in linux.</p>
  
  <p>My dongle is voice enabled (voice works with the windows application).
  I can check the voice activation in linux using the AT^CVOICE? command.
  This tells me how the raw audio stream should be organized.</p>
  
  <p>From question <a href="https://stackoverflow.com/questions/8367864/">How make use of the Voice API to make calls using Huawei 3g Modems?</a> I understand that the idea is to
  send commands on ttyUSB2 while passing raw audio data on ttyUSB1.</p>
  
  <p>I also understand that stack overflow user <a href="https://stackoverflow.com/users/1043421/sai-chaitanya">https://stackoverflow.com/users/1043421/sai-chaitanya</a> has voice working in Ubuntu in this way, so that this should indeed be the right approach.</p>
  
  <p>What is completely unclear to me is how to dial out voice calls, to check if someone is calling and to answer voice calls.</p>
  
  <p>Can anyone provide some clue or some pointer on this?</p>
  
  <p>Thanks!</p>
