VOIP Library for Mobile(Android/IOS) and Web Application

Question

I don't know it is suitable place for this question or not, if this is not the right place please redirect me to the right one. i am asking this question after spending 3-4 days. Please be with me.

I have a web app/Mobile app(Android and iOS) something like small ERP application. We want audio calling feature for the application, we have been looking for days but didn't get a suitable solution.

Our Requirement is Browser - Browser Calling, App to browser, App to App, browser to app

we don't need internet to phone feature. Ultimately we are looking for a solution that will allow user to call directly without knowing the phone number.

In my research i came across WebRTC, but didn't understand the logic.

so if there is any way (library or something) (free/paid), any kind of information will be helpful (article/library/webpage/explanation). To give me a path to move forward with the research.

thanks.
