Hi

I've managed to send SMSs and perform USSD etc. with ofono and the E272.

However, I'm unable to make a voice call with ofono.  I can make voice
call with python&pyserial.

Any pointers in right direction will be appreciated

#output from list-modem testscrip
./list-modems 
[ /huawei0 ]
    Features = sms gprs cbs net rat sim 
    Powered = 1
    Lockdown = 0
    Interfaces = org.ofono.SmartMessaging org.ofono.PushNotification
org.ofono.MessageManager org.ofono.ConnectionManager
org.ofono.CellBroadcast org.ofono.NetworkRegistration
org.ofono.SupplementaryServices org.ofono.Phonebook
org.ofono.RadioSettings org.ofono.SimManager 
    Online = 1
    Model = E272
    Manufacturer = huawei
    Serial = 357865013196535
##
Ciao

So all USB dongles support voice calls, however 99% of them do not
support audio.  There are two huawei devices that I know of that do.  Is
your device one of these?  Otherwise oFono does not enable the voicecall
functionality on such devices.

If your device does indeed support audio, then check the huawei modem
driver in plugins/huawei.c.  oFono performs some queries to determine if
your Huawei modem supports voice or not.  This magic might not be
working appropriately for your hardware.

There was no voicecall manager interface at all, it mean your modem did not support voice call.
