Does Huawei E3276 support voice call?

[Mangal]

I just want to know whether Huawei E3276 modem supports voice call? Does the current firmware support voice call? Or is a firmware upgrade required to enable it? Or is there no way to enable voice call? Text messaging and USSD work fine. I got the following details using DC - Unlocker 2 Client 1.00.1154:

Explained via live support chat. Modem/firmware does not support voice.
