How to Make voice phone call with MTS usb data modem ?

Hi, Since I have purchased MTS data modem device, I am looking for possibility to make call using this device. They have given me a phone number ie. my data card has a number just normal phone, they are using the mobile network, so it could be possible if I can also make call using it ?

Is it possible, if yes then what is the way ?

You can't make voice call if that modem has not support for it, if your modem has audio jack then it should have voice call facility, and above that , is MTS providing any such feature ?
