The history of the traditional telephone and telephony goes back to the beginning of the last century. In many places, there are more telephones than people. With the advent of fax machines, personal phone numbers, cell phones, satellite phones and dozens of other small examples of telephony, it is easy to see how calling others has become one of the primary means of communication in modern times.
However, with the advent of digital and wireless technologies, the telephone has evolved considerably.

The use of these technologies by telephone companies and operators has been reflected in the telephone network infrastructure for many years. For voice telephony, point-to-point microwave radio links and switched and routed digital calls (including Internet Protocol: IP) have been available for many years.
The growth of more than 3 billion subscribers worldwide and the progressive development of digital communications continue to put pressure on the overloaded and obsolete infrastructure of traditional telephone service providers. This growing demand has led to the development of digital and wireless technologies. This has led to the innovation of modern telephony, with broadband as the medium.

Calls made via broadband VoIP (Voice over Internet Protocol) services are all digital.
So what is VoIP: VoIP is the convergence of telephony and broadband. Instead of making, sending and receiving calls over the public switched telephone network (PSTN). VoIP is, as the name implies, a voice call made over a broadband connection, connected, routed and transmitted. Over the Internet rather than the traditional PSTN network.
If you have used the phone or live chat features of many instant messaging services. Offered on the Internet, you are using VoIP without realizing it. Transferring calls this way is much cheaper and more efficient than using traditional telephone services.
There are also independent carrier services that offer users VoIP communications over the Internet. A number of companies offer individuals and businesses the ability to make computer-to-computer and computer-to-phone calls. Some companies also offer services via network adapters that allow users to connect. And use traditional phones and make VoIP calls from their homes or offices.
