Are you using "option" linux driver?

I checked Huawei E1550, E153 and E173 modems on some systems and they have only 3 virtual serial ports.(using "option" driver)

Also you can check manually with minicom.

Usually ttyUSB0 is accepting  AT-commands, but will not reply with OK or ERROR, ttyUSB1 is used for audio, and ttyUSB2 is accepting AT-commands and replying  as normal serial modem.

Hello.

Try:

 <param name="controldevice_name" value="/dev/ttyUSB2"/>

 <param name="controldevice_audio_name" value="/dev/ttyUSB1"/>

It's worked for me.

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
