How to create an application for international calls so that you can directly call a phone number like TELZ, VOIPSCAN does? Can you point me to an article or examples? I can't understand how they work. Do you know any service? Maybe through the API you need to work. Please tell me who faced. Technologies, articles, ready-made open source applications, a book, anything so that I understand where they are going. Thanks in advance)

The topic of pairing IP and terrestrial telephony can be found on the example of https://www.asterisk.org/
