Is there any application for my Metro PCS Huawei Ascend android phone to be able to make wifi calls?

I have bought myself a Metro PCS Huawei Ascend android phone, as it was quite affordable than many other android phones! However, I was wondering if I could use it for making calls over wifi as well, as the place where I reside is a low service area, but it has a wifi connection. Do you think I would be required to download any application as such, to be able to use my phone for making wifi calls? I am quite new to Smartphone; hence, I would be really grateful if somebody could assist me appropriately! Thanks.
