This is Talmond Coy, i want visitors to be able to make and receive telephone calls on my website (using their Phone numbers). 

Hello. I'm not sure I understand your problem exactly. But perhaps one of these services will be useful to you. https://www.acethinker.com/desktop-recorder/video-chat-websites.html

@Talmond, you should please use descriptive titles for posts and not always the "This is.... "
as in this case for example
"make and receive telephone calls on my website".

And then attach explanatory pictures, not your logo.

I want visitors to be able to make and receive telephone calls on my website: www.Hify.online, (using their Phone numbers). 

What use should it have for visitors? Visitors can also make phone calls directly without the website.

Should a phone number be linked on the website so that visitors can click on it and be connected to the phone number?

Should the visitor call expensive telephone numbers for which the website operator gets money?

The helpers in the community should know what the purpose of these telephone numbers is and what advantages the visitors should have.
