[Freeswitch-users] Gsmopen : no audio in huawei e1550

[Dmitry Lysenko]

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.
