Hi, 

I can't get audio working with e1550 

I have this config :
    <interface id="1" name="gsm01">
      <param name="controldevice_name" value="/dev/ttyUSB0"/>
      <param name="controldevice_audio_name" value="/dev/ttyUSB3"/>

I tried swaping 0 and 3 but having same results

I am originating a call from softphone and answering it on cell phone but softphone doesn't get notified of being answered and keeps ringing 

Please help 

Thanks
