Busy Tone on ZTE MF190 Dongle


I have 2 dongles Huawei and ZTE attached on my Freepbx server. I have trouble having voice work on ZTE. lsusb and /dev/ttyUSB* automatically show ZTE and when I go to asterisk CLI the dongle is listed as dongle1 but when i call the number in the ZTE dongle it says number is busy.

When i run mode_switch command i also get error no switching mode given, plz advise

lsusb command:

usb_modeswitch Error:

I have a feeling its a problem with dongle, i wonder how i can enable voice calls on this kind of dongle
