Hi,

I have reproduced  such situation. It seems that controldevice_audio_name is pointing to wrong /dev/ttyUSBx.

I suggest try:

 <param name="controldevice_name" value="/dev/ttyUSB0"/>

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

if doesn't help try:

 <param name="controldevice_name" value="/dev/ttyUSB0"/>

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

P.S. Are you sure modem voice feature enabled?

option                  8690  0

Thanks for replying

As root: lsmod | grep option
Should be something like that:

option                 15351  6 

usb_wwan                8362  1 option

I guess so, I have CentOS 6 minimal installed 

how can I identify if this is option driver ?

Yes I saw this message on ttyUSB0 

I can not load gsmopen with ttyUSB2 or ttyUSB1

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.

2012/8/21 Sameer Khan <sameer2k3t@gmail.com>

It didn't for me, according to wvdial my modem is ttyUSB0 and ttyUSB3

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
