Failed to make voice calls (in/out)

[karlcchu]

Hi gurus

Here is the output of DC Unlocker:-

manufacturer - Huawei datacards
model - Auto detect

Found modem : K3715
Model : Huawei K3715
IMEI : 353**********
Firmware : 11.113.03.00.00
Dashboard version : UTPS11.300.05.15.143_MAC11.301.09.01.143
Serial NR. : DH5TAB2913004947
SIM Lock status : unlocked
Voice feature : enabled
Wrong codes entered : 0 (unlock attempts left : 10)

Mobile Partner has been installed successfully (version 11.302.09.01.539)

Everything is OK except making voice calls

It is strange that calls (inbound/outbound) were made but hung up automatically ...

Please help

Thank you

Hi Vincentas

I found the version (i.e. 11.302.09.01.539) in the said link was same as what I had installed

BTW, this version of Mobile Partner was downloaded and installed ...

However, the problem still re-occur when inbound/outbound calls were made, i.e. voice calls could be made but hung up at once automatically

Your help is appreciated ...

Try updating to other firmware. Maybe this will help.

Still, the result was same after upgrading the firmware (i.e. the version 11.113.03.00.00) ...
