How to make a voice call through a 3g modem using the terminal program in windows 7?

Question

Windows

Is it possible to make a voice call through the terminal by entering AT commands with the speaker and microphone turned on?
There is a modem that supports Huawei e3131 voice functions and calls through it work in the mobile parther program under windows 7.
I type the ATD84951112233 command in the terminal; The call goes on, but the speakers and microphone do not turn on. I tried before and after the dialing command, send the pickup command, the speakers and microphone still do not turn on.

There is a misunderstanding of how the voice modem works. You should familiarize yourself with the advanced AT voice modem kit, in particular your version.
